The Chesapeake Bay holds more aquatic life than most anglers ever stop to count. Stretching nearly 200 miles from the Susquehanna River in northern Maryland down to the Atlantic Ocean at Virginia Beach, it’s the largest estuary in the United States — and one of the most biologically diverse bodies of water on the East Coast.
Whether you’re casting from a pier in Annapolis, trolling the shipping channels near Baltimore, or wading the tidal flats of Virginia, you’re sharing the water with dozens of species that range from iconic sportfish to bizarre bottom-dwellers most people have never heard of. Some of these fish are year-round residents. Others migrate through seasonally, following temperature, salinity, and food. A few are invasive newcomers that have permanently changed the Bay’s ecosystem.
This guide covers 53 types of fish in the Chesapeake Bay — identified, described, and organized so you actually know what you’re looking at when something takes your line or surfaces near your boat. From striped bass to lined seahorses, here’s what lives in these waters.
1. Striped Bass (Rockfish)
If there’s one fish that defines the Chesapeake Bay, it’s the striped bass (Morone saxatilis). Known locally as rockfish, this is Maryland’s state fish and the Bay’s most celebrated sportfish. Striped bass are anadromous, meaning they spawn in freshwater rivers — particularly the Susquehanna, Potomac, and Rappahannock — before migrating to saltwater to feed and grow.
You’ll recognize them immediately by the seven or eight dark horizontal stripes running the length of their silver bodies. Adults commonly reach 18 to 36 inches in the Bay, though trophy fish exceeding 40 inches aren’t unheard of. They feed aggressively on menhaden, herring, and eels, which makes them highly responsive to live bait, bucktail jigs, and topwater lures during fall feeding frenzies.
Pro Tip: Fall is prime rockfish season in the Bay. Look for working birds — diving gulls and terns — over baitfish schools to locate feeding stripers near the surface.
The Chesapeake Bay produces the majority of the Atlantic striped bass population, making its health directly tied to the Bay’s overall ecological condition. Regulations around size limits and seasonal closures are strictly enforced to protect spawning stocks. If you’re targeting rockfish, make sure you’re up to date on current Bay fishing regulations before you head out.
2. Blue Catfish
The blue catfish (Ictalurus furcatus) is one of the Bay’s most controversial residents. Introduced into Virginia rivers in the 1970s and 1980s as a sportfish, it has since spread aggressively throughout the Chesapeake watershed and is now classified as an invasive species. Blue cats are now found in the James, Rappahannock, York, and Potomac rivers, and their populations continue to expand.
These are big fish. Blue catfish regularly exceed 20 pounds in the Bay system, and fish over 50 pounds have been documented. They have a slate-blue to gray coloration, a forked tail, and a flat, wide head with prominent barbels. Unlike native catfish species, blue cats are highly opportunistic predators that eat blue crabs, menhaden, shad, herring, and virtually anything else they can fit in their mouths — putting real pressure on native species.
For anglers, that aggression makes them a blast to target. Cut menhaden, chicken liver, and prepared catfish baits all work well. If you want to go deeper on catfish diversity across North America, the different types of catfish guide covers the full range of species worth knowing.
Key Insight: Virginia and Maryland actively encourage catching and keeping blue catfish with no size or creel limits in many areas — eating them is considered an ecological service to the Bay.
3. Channel Catfish
The channel catfish (Ictalurus punctatus) is the Bay’s native catfish counterpart, and it’s far more widespread across North American freshwater systems than its invasive blue cousin. In the Chesapeake watershed, channel cats thrive in the tidal freshwater portions of rivers like the Potomac, Susquehanna, and Patuxent.
Channel catfish are slimmer and more streamlined than blue catfish, with a deeply forked tail, scattered dark spots on younger fish, and a distinctly curved anal fin with 24 to 29 rays. They typically run smaller than blue cats in the Bay system — most fish fall between 1 and 5 pounds — but they’re scrappy fighters on light tackle and excellent table fare.
They feed primarily at night, using their sensitive barbels to detect food in low-visibility conditions. Cut bait, nightcrawlers, and stink baits all produce well. Channel catfish are a great target for bank anglers fishing tidal rivers after dark during the warmer months.
4. White Catfish
The white catfish (Ameiurus catus) is the smallest of the three catfish species commonly found in the Chesapeake system, and it’s the only one that’s truly native to Atlantic slope drainages. You’ll find white cats throughout the tidal freshwater and slightly brackish portions of Bay tributaries, tolerating salinity levels that would stress channel catfish.
White catfish have a moderately forked tail, a chunky body, and a rounded anal fin with 19 to 23 rays — a useful distinguishing feature when comparing them to channel cats. They’re typically white to pale gray on the belly with a darker back, and they rarely exceed 3 or 4 pounds in Bay waters.
Despite their modest size, white catfish are popular with recreational anglers targeting tidal rivers. They respond well to worms, cut bait, and small prepared baits fished near the bottom in slow-moving water or tidal pools.
5. Largemouth Bass
The largemouth bass (Micropterus salmoides) is one of the most sought-after freshwater sportfish in North America, and the Chesapeake Bay’s tidal river systems hold impressive populations. The Potomac River in particular has gained a national reputation as a world-class largemouth bass fishery, drawing tournament anglers from across the country.
Largemouth bass are identified by the dark lateral stripe running along their midline, their large mouth extending past the rear edge of the eye, and their divided dorsal fin. In the tidal Potomac and other Bay tributaries, fish in the 3- to 6-pound range are common, with occasional fish pushing 8 or 9 pounds.
Tidal largemouth bass relate strongly to aquatic vegetation — wild celery, hydrilla, and spatterdock are all prime habitat. Soft plastic baits, spinnerbaits, and topwater frogs all produce well depending on the season. If you’re gearing up for bass fishing, pairing the right fishing rod type with the right presentation makes a real difference in tidal current situations.
6. Smallmouth Bass
The smallmouth bass (Micropterus dolomieu) occupies the cooler, faster-moving headwaters of Chesapeake Bay tributaries rather than the warm, slow tidal sections preferred by largemouth. The upper Susquehanna River and its tributaries in Pennsylvania and northern Maryland are the heart of the Bay’s smallmouth bass range, though they’re also found in the upper Potomac and Shenandoah systems.
Smallmouth are bronze to olive-brown with vertical dark bars along their sides and a mouth that doesn’t extend past the rear of the eye — the key visual difference from largemouth. They’re pound-for-pound one of the hardest-fighting freshwater fish in North America, known for aerial jumps and powerful runs in current.
Crayfish imitations, tube baits, and small crankbaits are all effective in the rocky, clear-water habitats smallmouth prefer. Water temperature and clarity are critical — smallmouth are sensitive to both, and their populations in some upper Bay tributaries have faced stress from agricultural runoff and sedimentation.
Important Note: Smallmouth bass in the upper Chesapeake watershed have shown signs of reproductive disruption linked to endocrine-disrupting compounds in agricultural runoff. Catch-and-release is strongly encouraged in affected river sections.
7. White Perch
The white perch (Morone americana) is arguably the most abundant fish in the Chesapeake Bay and one of the most overlooked by anglers chasing bigger targets. These compact, silver-sided fish are found throughout the Bay and its tributaries year-round, thriving in both brackish and freshwater environments with remarkable adaptability.
White perch have a deep, compressed body, a silver to olive-gray coloration, and no distinct lateral stripe — which helps distinguish them from young striped bass. They typically run 6 to 10 inches in length, though fish over 12 inches are considered trophies. They school in large numbers, which means once you find them, the action can be fast and constant.
Light spinning tackle with small jigs, worms, or grass shrimp is the classic approach. White perch are outstanding table fare — mild, flaky, and sweet — and many Bay locals consider them among the best-eating fish in the estuary.
8. Yellow Perch
The yellow perch (Perca flavescens) brings a flash of color to the Chesapeake Bay’s winter fishing calendar. These strikingly beautiful fish — golden-yellow with six to eight dark vertical bars and orange-tinted lower fins — run up Bay tributaries to spawn in late winter and early spring, creating one of the most popular cold-weather fishing events in the region.
Yellow perch are found primarily in the freshwater and tidal freshwater sections of rivers like the Choptank, Nanticoke, and Patuxent. Most fish run 8 to 12 inches, but larger specimens in the 14- to 15-inch range are caught each season. They’re schooling fish, and when you hit a school during the winter run, you can catch dozens in a single outing.
Small jigs tipped with minnows or worms fished slowly near the bottom are the standard approach. Yellow perch are considered superb table fish, and their winter run is a cherished tradition for generations of Chesapeake anglers.
9. Black Crappie
The black crappie (Pomoxis nigromaculatus) is a panfish species found in the freshwater tributaries of the Chesapeake Bay, particularly in reservoirs, ponds, and slow-moving river sections with abundant structure. While not a saltwater Bay species, black crappie are an important part of the watershed’s recreational fishery.
Black crappie have a deep, laterally compressed body covered in irregular dark spots scattered across a silver-green background — unlike white crappie, which have more distinct vertical barring. They’re typically 8 to 12 inches long and are almost always found near submerged structure: fallen timber, dock pilings, brush piles, and aquatic vegetation edges.
Small tube jigs, tiny spinners, and live minnows suspended under a float are the go-to presentations. Crappie are light biters and reward patience and finesse over power fishing. They’re excellent eating, with a mild white flesh that holds up well to a variety of cooking methods.
11. Bluegill
The bluegill (Lepomis macrochirus) is the quintessential panfish of the Chesapeake Bay watershed — the fish that introduces more kids to angling than any other species in the region. Found in virtually every freshwater tributary, pond, and reservoir connected to the Bay system, bluegill are accessible, aggressive, and remarkably fun on ultralight tackle.
Bluegill are identified by their deep, rounded body, the distinctive dark blue-black “ear flap” at the rear of the gill cover, and the dark spot at the base of the dorsal fin. Their sides are olive to orange-yellow, and breeding males develop vivid orange-red bellies. Most fish run 6 to 9 inches, but large bluegill in productive water can push 11 or 12 inches.
Small hooks baited with worms or crickets are all you need. Bluegill are aggressive feeders near beds during the spawning season and remain active through much of the warm-weather months in shallow, weedy areas.
12. Pumpkinseed Sunfish
The pumpkinseed sunfish (Lepomis gibbosus) is one of the most colorful fish you’ll encounter in the Chesapeake Bay’s freshwater tributaries. Often mistaken for bluegill, pumpkinseeds are distinguished by their vivid orange-red spot on the tip of the dark ear flap, their heavily spotted sides with wavy blue-green lines on the cheeks, and their more rounded body shape.
Pumpkinseeds prefer clear, weedy water with soft bottoms — the kind of habitat found in quiet coves, slow river backwaters, and tributary ponds throughout the watershed. They’re smaller on average than bluegill, with most fish running 5 to 8 inches, but what they lack in size they make up for in visual impact.
Their hard, shell-crushing teeth allow them to eat snails and small mollusks in addition to insects and worms — a dietary flexibility that sets them apart from other sunfish species. Small hooks with worms or tiny artificial lures work well, and they’re often caught alongside bluegill in mixed-species schools.
13. Redear Sunfish
The redear sunfish (Lepomis microlophus), sometimes called the shellcracker for its ability to crush snails and small clams with its pharyngeal teeth, is found in the warmer, slower sections of Chesapeake Bay tributaries. It’s less common than bluegill or pumpkinseed in the Bay watershed but present in suitable habitat, particularly in Virginia’s coastal plain rivers.
Redear sunfish look similar to pumpkinseed but are identified by the red or orange margin on the rear of their ear flap, their less colorful body, and their larger average size — fish over 10 inches are not unusual in productive water. They tend to hold in deeper water than other sunfish and feed heavily on bottom-dwelling invertebrates.
Fishing for redear requires a slower, more deliberate approach than typical panfishing. Small worms or snail imitations fished on the bottom near submerged timber or rocky substrate produce the best results.
14. Atlantic Menhaden
The Atlantic menhaden (Brevoortia tyrannus) may not be a fish you ever try to catch intentionally, but it is arguably the most ecologically important fish in the entire Chesapeake Bay. Menhaden are filter feeders that consume enormous quantities of phytoplankton and zooplankton, helping to maintain water clarity and quality throughout the estuary.
They are also the primary food source for nearly every predator in the Bay — striped bass, bluefish, weakfish, osprey, dolphins, and even humpback whales feed heavily on menhaden schools. Locally called “bunker” or “pogy,” menhaden travel in enormous schools that can turn the surface of the water dark and oily from their body secretions.
Key Insight: Menhaden are commercially harvested for fish oil, fishmeal, and omega-3 supplements. The Bay’s menhaden fishery is one of the largest single-species fisheries on the East Coast by volume, and its management is a persistent point of ecological debate.
As an angler, you’ll use menhaden as bait more often than you’ll target them directly. Snagging bunker with a cast net or treble hook rig is a standard technique for live-lining them to striped bass, bluefish, and cobia.
15. American Shad
The American shad (Alosa sapidissima) is one of the Bay’s great comeback stories. Once devastated by overfishing and dam construction that blocked spawning runs, shad populations have recovered significantly following decades of restoration efforts, including fish passage improvements on the Susquehanna River. They are the largest member of the herring family found in North American waters.
American shad are bright silver with a row of dark spots behind the gill cover and a deeply forked tail. They run up Bay tributaries in spring to spawn, typically from March through May, creating one of the most exciting seasonal fisheries in the region. Anglers target them with small darts, spoons, and shad rigs drifted in river current.
Shad don’t eat during their spawning run — they strike out of aggression or reflex — which makes them a uniquely challenging and rewarding target. Roe shad (females) are prized for their eggs, a regional delicacy with a long culinary tradition in the Bay area.
16. Hickory Shad
The hickory shad (Alosa mediocris) is the American shad’s smaller, more aggressive cousin, and it runs the same spring spawning migration through Chesapeake Bay tributaries. Hickory shad are typically a few weeks ahead of American shad in their timing, making them the first sign of the spring shad run for tributary anglers.
Hickory shad have a more pronounced lower jaw that juts out past the upper jaw — a reliable field identification mark — along with a row of spots that extends further along the body than on American shad. They average 1 to 2 pounds and are noticeably more aggressive strikers than their larger relatives.
Small spoons, in-line spinners, and shad darts in chartreuse or white are the standard presentation. Hickory shad are acrobatic fighters that jump repeatedly when hooked, making them a favorite of light-tackle anglers who fish the spring river runs each year.
17. Alewife
The alewife (Alosa pseudoharengus) is one of four river herring species that migrate through the Chesapeake Bay system, and it plays a critical role as a forage fish for larger predators throughout the estuary. Alewives are small — typically 9 to 12 inches — with a deep, compressed body, a single dark spot behind the gill cover, and a large eye relative to their head size.
They migrate into Bay tributaries in early spring to spawn in freshwater, often in large, dense schools that attract striped bass, bluefish, and osprey. After spawning, adults return to saltwater while juveniles spend the summer in tidal rivers before migrating out in fall.
Alewife populations have declined significantly over the past century due to dam construction, habitat loss, and overfishing. Restoration efforts, including fish ladders and targeted harvest reductions, are ongoing across the Bay watershed. You’re most likely to encounter them as bait or as part of a predator feeding frenzy near river mouths in spring.
18. Blueback Herring
The blueback herring (Alosa aestivalis) is nearly identical to the alewife in size and appearance, and the two species are collectively referred to as “river herring” throughout the Bay region. The key visual difference is the eye size — blueback herring have a smaller eye relative to head size — and their slightly darker, more blue-tinted back.
Blueback herring spawn slightly later in spring than alewives, preferring faster-moving water in river channels. Like alewives, they’re critically important forage fish that support the Bay’s food web from striped bass to osprey to river otters.
Both river herring species have faced dramatic population declines and are subject to strict harvest restrictions in Maryland and Virginia. Understanding the broader diversity of fish species across different ecosystems helps put the Bay’s forage fish crisis in broader ecological context.
19. Atlantic Sturgeon
The Atlantic sturgeon (Acipenser oxyrinchus) is a living fossil — a species that has existed largely unchanged for more than 120 million years. In the Chesapeake Bay, Atlantic sturgeon are federally endangered, the result of centuries of overfishing for their prized roe (caviar) and meat, combined with habitat degradation that blocked spawning migrations.
These are massive fish. Atlantic sturgeon can reach 14 feet in length and exceed 800 pounds, though Bay fish are typically smaller. They’re immediately recognizable by their shark-like body, five rows of bony plates called scutes along their sides, and the distinctive rostrum (snout) with four barbels hanging beneath it. They feed by vacuuming invertebrates from the bottom with their protrusible, toothless mouths.
Important Note: Atlantic sturgeon are federally protected under the Endangered Species Act. If you accidentally hook one, handle it carefully in the water and release it immediately without removing it from the water. Report the catch to the appropriate state agency.
Recovery efforts are showing some progress, with juvenile sturgeon increasingly documented in the James and other Bay rivers. Their return is considered one of the most important conservation milestones in Bay history.
20. Shortnose Sturgeon
The shortnose sturgeon (Acipenser brevirostrum) is the smaller of the two sturgeon species found in the Chesapeake Bay system, and like its larger relative, it is federally endangered. Shortnose sturgeon rarely exceed 4 feet in length and are distinguished from Atlantic sturgeon by their shorter, broader snout and the wider spacing of their mouth relative to their head width.
In the Chesapeake watershed, shortnose sturgeon are primarily found in the Potomac River and a few other major tributaries. Unlike Atlantic sturgeon, which migrate to the ocean between spawning seasons, shortnose sturgeon tend to remain in freshwater or tidal freshwater environments year-round.
Their populations are small and their recovery slow, largely because shortnose sturgeon mature late and reproduce infrequently. They are rarely encountered by recreational anglers, but accidental catches do occur. All handling rules that apply to Atlantic sturgeon apply equally to shortnose sturgeon.
21. American Eel
The American eel (Anguilla rostrata) is one of the most ecologically fascinating fish in the Chesapeake Bay — and one of the strangest in terms of its life history. Unlike most fish, eels are catadromous: they live their adult lives in freshwater but migrate to the ocean to spawn. All American eels spawn in the Sargasso Sea in the Atlantic Ocean, and their larvae drift on ocean currents back to the coast before entering estuaries and rivers.
Eels are long, snake-like fish with smooth, scaleless skin covered in mucus, a continuous dorsal-anal fin running most of their body length, and a small, pointed head. They range in color from olive-brown to yellow-green on the sides with a pale belly. In the Bay, eels are found from tidal freshwater all the way into saltwater, hiding under rocks, in crevices, and in soft bottom sediment during the day.
American eels are excellent bait for striped bass and catfish, and they support a significant commercial fishery. Their populations have declined sharply over recent decades, prompting management concerns in both the U.S. and Canada.
22. Atlantic Croaker
The Atlantic croaker (Micropogonias undulatus) is one of the most abundant and widely caught fish in the lower and middle Chesapeake Bay during summer and fall. Named for the distinctive croaking sound males produce by vibrating their swim bladder, croakers are a staple of Bay pier fishing and small-boat angling throughout the region.
Croakers have a slightly downturned mouth with small barbels on the chin — adaptations for bottom feeding — and a body that’s silver to bronze with irregular dark wavy lines and spots. Most fish run 8 to 14 inches in Bay waters, though larger specimens are caught each season. They feed on worms, small crustaceans, and mollusks in shallow to moderate-depth water over soft bottoms.
Simple bottom rigs with bloodworms, squid, or cut crab are all effective. Atlantic croaker are excellent eating fish with a mild, sweet flavor, and they’re one of the most democratic Bay species — accessible to anglers of all experience levels from shore or boat.
23. Spot
The spot (Leiostomus xanthurus) is another beloved bottom fish of the Chesapeake Bay, closely related to the croaker and often caught alongside it. Spot are identified by the small, distinct black spot just behind the upper edge of the gill cover — the feature that gives them their name — along with faint diagonal stripes on their sides and a slightly forked tail.
Spot arrive in the Bay in late spring and summer, feeding in shallow, soft-bottom areas on worms and small invertebrates. They’re typically smaller than croakers, with most fish running 6 to 10 inches, but they make up for their modest size with sheer abundance. During good years, spot are everywhere in the Bay’s tidal creeks and shallow flats.
Light tackle with small hooks and bloodworms or peeler crab is the standard approach. Spot are considered excellent table fare, and “spot and croaker” fishing is a beloved late-summer tradition along the entire length of the Bay.
24. Weakfish
The weakfish (Cynoscion regalis) was once one of the most popular sportfish in the Chesapeake Bay, but populations have declined dramatically since the 1980s and the species now receives far less attention than it once did. Named for the soft, easily torn tissue around their mouth — which causes them to “throw the hook” frequently — weakfish are beautiful fish with iridescent spots and a golden-green sheen along their backs.
Weakfish have a large mouth with two prominent canine teeth at the front of the upper jaw, a feature shared with their relative the red drum. They’re found in the Bay from spring through fall, feeding on menhaden, shrimp, and small fish in channels and over grass beds. Most fish caught today run 12 to 20 inches, though larger fish were historically common.
Soft plastic shrimp imitations, small bucktails, and live spot or shrimp are all effective presentations. Weakfish bite best at night around lighted docks and channel edges, and their delicate, sweet flesh makes them a prized catch for those lucky enough to find them.
25. Red Drum (Redfish)
The red drum (Sciaenops ocellatus), also known as redfish or channel bass, is primarily a lower Bay species, most commonly encountered in the Virginia portion of the Chesapeake near the mouth and in the coastal bays behind the barrier islands. These powerful, copper-bronze fish are distinguished by one or more black spots at the base of the tail — a feature so consistent it’s the most reliable field ID mark for the species.
Red drum can grow to impressive sizes — fish over 40 inches (“bull reds”) are caught in the lower Bay each fall. Smaller “puppy drum” in the 16- to 27-inch range are more common inshore and provide excellent sport on medium tackle. They feed on blue crabs, shrimp, and small fish, often in very shallow water where their tails break the surface as they root along the bottom.
Pro Tip: “Tailing” red drum in shallow grass flats are one of the most exciting sight-fishing targets in the Bay. A crab imitation or live finger mullet cast ahead of a tailing fish is the classic presentation.
26. Black Drum
The black drum (Pogonias cromis) is the largest member of the drum family found in the Chesapeake Bay, and it’s a fish that many Bay anglers overlook in favor of its more glamorous red cousin. Black drum are dark gray to black with a deep, heavy body, a blunt head, and a cluster of prominent barbels hanging from the lower jaw — tools for locating oysters, clams, and crabs on the bottom.
In the Bay, black drum are most commonly encountered near oyster reefs, bridge pilings, and channel edges in the lower and middle Bay from spring through early summer. Fish in the 20- to 40-pound range are regularly caught, and larger specimens exceeding 60 pounds are possible. They’re powerful, bulldogging fighters that test heavy tackle and strong knots.
Natural baits — peeler crab, clam, and cut menhaden — fished directly on the bottom near structure produce the best results. Smaller black drum under about 15 pounds are considered better eating than large adults, which can become coarse and wormy.
27. Northern Snakehead
The northern snakehead (Channa argus) is the Bay watershed’s most infamous invasive fish, first discovered in a Crofton, Maryland pond in 2002 and now established throughout the Potomac River and many of its tributaries. Native to China, Russia, and Korea, snakeheads are obligate air breathers with a specialized suprabranchial organ that allows them to survive in low-oxygen water and even move short distances overland.
Snakeheads are long, cylindrical fish with a flattened head, a large mouth full of sharp teeth, and a pattern of dark brown blotches on a tan or bronze body. They can reach 3 feet or more in length and are apex predators in the tidal freshwater environments they’ve colonized, feeding aggressively on fish, frogs, crayfish, and small birds or mammals.
Despite their invasive status, snakeheads have developed a dedicated following among sport anglers. They strike topwater lures explosively, fight hard, and are actually good eating. In Maryland and Virginia, there are no size or creel limits — you’re encouraged to catch and keep every one you find.
28. Bluefish
The bluefish (Pomatomus saltatrix) is the Bay’s most ferocious seasonal visitor, arriving in spring and fall to tear through schools of menhaden and herring with a feeding aggression unmatched by nearly any other East Coast species. Bluefish have a reputation for chomping through leaders, cutting off fingers, and continuing to bite even after being landed — all of which is deserved.
They’re identified by their blue-green back, silver sides, a deeply forked tail, and a mouth full of razor-sharp, triangular teeth. Bay bluefish range from small “snapper blues” of 6 to 8 inches in late summer to “chopper blues” exceeding 15 pounds during fall runs. They travel in large schools that push baitfish to the surface, creating spectacular surface feeding events visible from miles away.
Wire or heavy fluorocarbon leaders are essential when targeting bluefish — monofilament won’t survive their teeth. Spoons, poppers, and cut menhaden chunks all produce. Bluefish are oily and best eaten fresh; they don’t keep well and should be bled immediately after landing for the best table quality.
29. Spanish Mackerel
The Spanish mackerel (Scomberomorus maculatus) is a warm-weather visitor to the lower and middle Chesapeake Bay, typically arriving in June and departing by October as water temperatures drop. Fast, sleek, and brilliantly colored, Spanish mackerel are among the most exciting light-tackle targets in the Bay.
Spanish mackerel are identified by their iridescent blue-green back, silver sides covered in round golden-yellow spots, and their deeply forked, dark-tipped tail. They’re built for speed, chasing down bay anchovies, silversides, and small menhaden near the surface. Most Bay fish run 14 to 22 inches and 1 to 3 pounds, though larger fish are caught each season.
High-speed trolling with small spoons or Clark spoons is the classic approach, but casting small metal jigs or live-lining bay anchovies under working birds also produces. Spanish mackerel have a stronger flavor than many Bay fish but are excellent when grilled or smoked fresh.
30. Cobia
The cobia (Rachycentron canadum) is one of the most prized inshore sportfish in the lower Chesapeake Bay, and the Bay’s late spring cobia run draws anglers from across the mid-Atlantic region. Cobia are large — fish over 50 pounds are caught regularly in Bay waters — and they combine hard-fighting ability with a willingness to take live bait, jigs, and even flies.
Cobia are dark brown to black on the back with a distinctive white or cream lateral stripe running from the eye to the tail. Their flat head and slightly depressed snout give them a distinctive silhouette. They frequently associate with large rays, sharks, buoys, and channel markers, making sight-fishing a viable and thrilling approach during the spring run.
Live eels, large bucktail jigs, and swim shads are the top baits. The sight-fishing approach — spotting a cobia following a ray and casting ahead of it — is one of the most exciting experiences in Bay angling. Cobia are outstanding on the table, with firm, white flesh that holds up to grilling, baking, or blackening.
31. Sheepshead
The sheepshead (Archosargus probatocephalus) is an underrated Bay species that rewards anglers willing to learn its habits. Named for its uncanny human-like teeth — broad, flat incisors used to crush barnacles, oysters, and crustaceans — sheepshead are found around hard structure throughout the Bay, particularly in the lower Bay near bridge pilings, jetties, and oyster reefs.
Sheepshead have a deep, compressed body with bold black vertical bars on a silver-gray background, similar in pattern to a convict or black drum. They’re cautious, deliberate biters — notorious for stealing bait without getting hooked — which makes them a technical challenge for anglers accustomed to more aggressive species.
Fiddler crabs, sand fleas, and barnacles scraped from pilings are the most effective baits. A light touch on the rod and a quick hookset are essential. Sheepshead are superb table fish with sweet, firm white flesh, and their growing presence in the Bay reflects warming water temperatures over recent decades.
32. Flounder (Summer Flounder)
The summer flounder (Paralichthys dentatus), known locally as “fluke,” is the Bay’s most popular flatfish and a favorite target of bottom anglers throughout the warmer months. Summer flounder are left-eyed flatfish — both eyes are on the left side of the body — and they lie camouflaged on sandy or muddy bottoms, ambushing prey with explosive speed.
Summer flounder are found throughout the Bay from May through October, moving into shallower water to feed on grass shrimp, small fish, and crustaceans. They’re identified by their brown to olive upper side covered in pale spots and ocellated markings, and their brilliant white underside. Fish in the 14- to 20-inch range are common in Bay waters, though larger fish exceeding 24 inches are caught each season.
Drifting bucktail jigs tipped with squid strips or Gulp! baits over sandy bottom near channel edges is the standard technique. Matching your reel type to a sensitive rod helps detect the subtle “thump” of a flounder take before it drops the bait.
33. Winter Flounder
The winter flounder (Pseudopleuronectes americanus) is the cold-weather counterpart to summer flounder, entering the Bay in late fall and winter when water temperatures drop and summer flounder have departed. Unlike summer flounder, winter flounder are right-eyed — both eyes are on the right side of the body — and they’re significantly smaller, with most fish running 10 to 14 inches.
Winter flounder have a rounder body shape than summer flounder, a small mouth with thick lips, and a dark brown to reddish-brown upper surface with small, scattered spots. They feed on worms, small crustaceans, and algae in shallow, soft-bottom areas during the winter months.
Populations of winter flounder have declined significantly in the Chesapeake Bay over recent decades, and the species is now far less abundant than it once was. Bloodworms or sandworms on small hooks fished on the bottom in tidal creeks and shallow flats during winter are the traditional approach.
34. Hogchoker
The hogchoker (Trinectes maculatus) is a small, native flatfish that’s far more common in the Chesapeake Bay than most anglers realize — mostly because it’s rarely targeted intentionally and is often dismissed as a “trash fish” when caught incidentally. Hogchokers are right-eyed flatfish with a rounded, oval body, no pectoral fins, and a distinctive pattern of dark brown bands across their upper surface.
They’re found throughout the Bay and its tributaries from freshwater to fully saline conditions, tolerating a wider salinity range than virtually any other flatfish in the estuary. Most hogchokers are 4 to 6 inches long and spend their time partially buried in soft sediment, feeding on detritus and small invertebrates.
The name “hogchoker” reportedly comes from the colonial era, when these fish were considered so bony and unpalatable that even hogs wouldn’t eat them. While that reputation is somewhat exaggerated, they’re not a table fish and are typically released when caught.
35. Striped Killifish
The striped killifish (Fundulus majalis) is one of the hardiest and most adaptable small fish in the Chesapeake Bay, capable of surviving in conditions that would kill most other species. Found in saltmarsh creeks, tidal flats, and shallow estuarine areas throughout the Bay, striped killifish are ecologically important as forage for larger predators and as consumers of mosquito larvae and small invertebrates.
Males are identified by bold black vertical bars on their sides, while females have one to three horizontal stripes — a striking sexual dimorphism that can make the two sexes look like different species. Most fish run 3 to 5 inches. They’re extremely tolerant of temperature extremes, low oxygen, and wide salinity swings.
Striped killifish are commonly used as live bait for flounder, striped bass, and weakfish. They’re easily caught with small mesh traps or dip nets in shallow marsh creeks and are among the most effective live baits available to Bay anglers.
36. Mummichog
The mummichog (Fundulus heteroclitus) is the Bay’s most abundant small fish by sheer numbers and one of the most scientifically studied vertebrates on Earth. These small, robust killifish are found in every saltmarsh, tidal creek, and mudflat in the Chesapeake Bay system, thriving in conditions — extreme temperature, low oxygen, pollution — that would kill virtually any other fish.
Mummichogs are chunky, with a blunt head, large scales, and a rounded tail. Males display olive-green sides with silvery vertical bars and vivid yellow-orange fins during breeding season; females are duller with horizontal striping. Most fish are 2 to 4 inches long.
Because of their extreme hardiness, mummichogs have been used extensively in toxicology research and were even sent to space aboard Skylab in 1973 — the first fish to spawn in microgravity. In the Bay, they serve as critical forage for herons, egrets, and juvenile striped bass in saltmarsh habitats.
37. Atlantic Needlefish
The Atlantic needlefish (Strongylura marina) is one of the most distinctive-looking fish in the Chesapeake Bay — a long, slender, almost comically elongated fish with a beak-like jaw lined with sharp teeth. Needlefish are surface dwellers that skitter across the water when startled, sometimes leaping completely clear of the surface in a series of rapid skips.
They’re found throughout the Bay in warm months, particularly in shallow grass beds and near the surface over open water. Their long, narrow bodies are bright silver-green on the sides with a pale belly, and they typically run 12 to 24 inches in length. Needlefish feed on small fish and shrimp near the surface, often visible as thin silver flashes in calm, shallow water.
Needlefish are rarely targeted by anglers but frequently caught incidentally on small lures or live bait. Their green-tinted bones make them unappealing to many people as table fare, though the flesh itself is perfectly edible.
38. Bay Anchovy
The bay anchovy (Anchoa mitchilli) is the most abundant fish in the Chesapeake Bay by sheer numbers — estimates suggest the Bay’s bay anchovy population numbers in the trillions during peak summer months. These tiny, translucent fish rarely exceed 3 inches in length but are the foundation of the Bay’s food web, serving as the primary forage for striped bass, bluefish, weakfish, Spanish mackerel, and virtually every other predatory species in the estuary.
Bay anchovies are identified by a large mouth that extends well past the eye, a single silver stripe along the midline, and a nearly transparent body that makes their internal organs visible. They school in enormous, dense aggregations that can cloud the water and attract surface-feeding predators in spectacular fashion.
When you see birds diving and predators crashing baitfish at the surface, there’s a good chance bay anchovies are the bait being targeted. Small sabiki rigs can be used to catch them for live bait, and they’re one of the most effective live baits available for Spanish mackerel and bluefish.
39. Spottail Shiner
The spottail shiner (Notropis hudsonius) is a small, native minnow found in the freshwater tributaries of the Chesapeake Bay watershed, particularly in rivers with sandy or gravel bottoms and moderate current. It’s identified by the distinctive black spot at the base of the tail — the feature that gives the species its name — along with a silvery body and a slightly arched back.
Spottail shiners typically run 2 to 4 inches and travel in loose schools in shallow, clear water. They feed on insects, small crustaceans, and plant material and serve as important forage for bass, perch, and larger predatory fish in tributary systems.
Anglers use spottail shiners as live bait for bass and walleye in freshwater tributary fishing, and they can be caught with small mesh traps or seines in shallow, sandy-bottomed streams. They’re a good indicator of water quality — spottail shiners prefer clean, well-oxygenated water and are less tolerant of pollution than some other minnow species.
40. Gizzard Shad
The gizzard shad (Dorosoma cepedianum) is a large, deep-bodied member of the herring family that’s found throughout the freshwater and tidal freshwater portions of the Chesapeake Bay system. Gizzard shad are named for their muscular, gizzard-like stomach that grinds up the algae and detritus they filter from the water column.
They’re identified by a deeply forked tail, a single elongated dorsal fin ray that extends well past the rest of the fin, and a dark spot behind the gill cover. Adults commonly reach 12 to 17 inches — much larger than most other shad-family fish — and have a robust, slab-sided body.
Gizzard shad are not typically targeted by anglers for sport or food, but they’re extremely important as forage for striped bass, catfish, and other large predators in freshwater and tidal environments. Large gizzard shad are commonly used as cut bait for big blue catfish and flathead catfish in Bay tributaries.
41. Sandbar Shark
The sandbar shark (Carcharhinus plumbeus) is the most common large shark in the Chesapeake Bay and one of the most abundant coastal shark species on the entire East Coast. The Bay serves as a critical nursery habitat for sandbar sharks, with juveniles spending their first several years in the relative safety of the estuary’s shallow, food-rich waters before moving offshore as adults.
Sandbar sharks are identified by their high, erect first dorsal fin — proportionally the largest of any requiem shark — along with their gray to bronze coloration and a stocky, robust body. Juveniles commonly encountered in the Bay run 2 to 4 feet, while adults can reach 8 feet and 200 pounds.
They feed on bottom fish, rays, and crustaceans and are generally not considered a significant threat to humans, though all large sharks deserve respect. Sandbar sharks are a federally managed species with strict harvest restrictions due to their slow reproductive rate.
42. Smooth Dogfish
The smooth dogfish (Mustelus canis) is a small, slender shark that’s extremely common in the Chesapeake Bay from spring through fall, often caught incidentally by bottom anglers targeting croaker, spot, and flounder. Smooth dogfish are identified by their flat, pavement-like teeth — adapted for crushing crabs and lobsters rather than cutting prey — along with their gray to brown coloration and slender, elongated body.
Most smooth dogfish in the Bay run 2 to 3.5 feet in length. They’re viviparous, giving birth to live pups rather than laying eggs, and the Bay’s warm, shallow waters serve as important pupping habitat. Smooth dogfish are highly migratory, arriving in the Bay in spring and departing for offshore waters in fall.
While not a primary target species, smooth dogfish are caught regularly on bottom rigs with cut bait. They’re edible but not widely eaten in the U.S., though they’re marketed as “cape shark” in some areas. Understanding the different fishing approaches for bottom species helps anglers manage incidental shark catches effectively.
43. Bull Shark
The bull shark (Carcharhinus leucas) is the Bay’s most formidable shark and one of the few species capable of tolerating the full range of salinity found in the estuary — from the brackish upper Bay all the way to freshwater river systems. Bull sharks are considered one of the three shark species most frequently implicated in unprovoked attacks on humans worldwide, alongside great whites and tiger sharks.
Bull sharks are heavily built, with a broad, rounded snout, small eyes, and a gray back with a white belly. Adults in the Bay typically run 6 to 9 feet and can exceed 300 pounds. They feed on a wide variety of prey including fish, rays, sea turtles, and other sharks, and their presence in the Bay has increased with warming water temperatures over recent decades.
Important Note: Bull shark sightings and catches in the Chesapeake Bay have become more frequent in recent summers. Swimmers and waders in lower Bay waters should be aware of their presence, particularly in warm, murky conditions near river mouths.
44. Cownose Ray
The cownose ray (Rhinoptera bonasus) is one of the most visible and recognizable animals in the Chesapeake Bay during summer months, often seen in large aggregations of hundreds or thousands of individuals gliding just below the surface in formation. These diamond-shaped rays have a distinctive bi-lobed head — the “cownose” — along with a long, whip-like tail and a wingspan that can reach 3.5 feet.
Cownose rays are powerful excavators of the Bay’s bottom, using their pectoral fins to fan sediment and expose buried clams, oysters, and soft-shell crabs. Their impact on shellfish beds has made them controversial among Bay watermen, though their ecological role is complex and their population dynamics are not fully understood.
Rays are not typically targeted by recreational anglers, but they’re spectacular to observe from a boat. They frequently leap completely clear of the water — a behavior that’s visually stunning but whose purpose remains a subject of scientific debate. Cownose rays are also one of the coastal species whose range has shifted northward with changing ocean temperatures.
45. Clearnose Skate
The clearnose skate (Raja eglanteria) is the most common skate in the Chesapeake Bay, a flat, diamond-shaped relative of sharks that rests on sandy and muddy bottoms throughout the estuary. Unlike rays, skates have a thicker, more muscular tail and reproduce by laying leathery egg cases — the “mermaid’s purses” often found washed up on Bay beaches.
Clearnose skates are identified by the translucent, clear patches on either side of their snout — the feature that gives them their name — along with a brown to tan upper surface with dark spots and a white belly. Most Bay skates run 18 to 30 inches across the disc and feed on crustaceans, worms, and small fish on the bottom.
They’re frequently caught by bottom anglers using cut bait or bloodworms. Skates are sometimes eaten — the “wings” can be prepared similarly to scallops — but they’re most often released. Their egg cases are commonly found on Bay beaches from spring through summer.
46. Butterfly Ray
The butterfly ray (Gymnura micrura) is the most distinctive of the Bay’s ray species, immediately recognizable by its extremely wide, short disc — almost twice as wide as it is long — which gives it a butterfly-like silhouette unlike any other ray in the estuary. The tail is very short and lacks the venomous spine found in stingrays, making butterfly rays less hazardous to handle than other ray species.
Butterfly rays are found in the lower and middle Bay during warm months, resting on sandy bottoms in shallow to moderate-depth water. Their upper surface is gray to brown with a mottled pattern that provides excellent camouflage against sandy substrate. Most Bay butterfly rays have a disc width of 18 to 30 inches.
They feed on small fish, shrimp, and crustaceans and are caught incidentally by bottom anglers. Butterfly rays are rarely targeted deliberately but are interesting incidental catches that often surprise anglers unfamiliar with the Bay’s ray diversity.
47. Oyster Toadfish
The oyster toadfish (Opsanus tau) is one of the Bay’s most characterful residents — ugly, vocal, and surprisingly fascinating. These bottom-dwelling ambush predators are found throughout the Bay and its tributaries, hiding under rocks, inside empty shells, in crab pots, and in any other available crevice. They’re year-round Bay residents, one of the few species that doesn’t migrate seasonally.
Toadfish are identified by their large, flattened head, enormous frog-like mouth, fleshy skin flaps and warts covering their body, and mottled brown coloration. They produce a distinctive boat-whistle call during spawning season — a foghorn-like “booooop” that males use to attract females to their nest sites. This sound is audible from boats and even from shore near shallow water.
Toadfish are notorious for stealing bait from crab pots and bottom rigs. They have sharp spines on their dorsal fin and gill covers that can inflict painful wounds, so handle them carefully. Despite their appearance, toadfish are excellent table fish — their firm, white flesh is compared to monkfish by those willing to look past the exterior.
48. Northern Puffer
The northern puffer (Sphoeroides maculatus), also called a “blowfish” or “sugar toad” in the Bay region, is one of the most entertaining fish you’ll encounter in Chesapeake waters. When threatened, puffers inflate themselves into a spiny ball by rapidly ingesting water — a defense mechanism that makes them nearly impossible for predators to swallow.
Northern puffers are found in the Bay from late spring through fall, particularly in the lower and middle Bay over sandy bottoms near grass beds and oyster reefs. They have a chunky, rounded body, a small mouth with fused beak-like teeth, and a back covered in small prickles. Most Bay puffers run 6 to 12 inches.
Puffers are caught regularly on light bottom rigs with bloodworms or squid. Their internal organs contain tetrodotoxin — a potent neurotoxin — but the flesh of properly cleaned northern puffers is completely safe and considered a delicacy in the Bay region, where cleaned puffer tails are sold as “sea squab.” If you want to learn more about puffer fish toxicity across species, the full breakdown of puffer fish toxicity is worth reading before handling any species.
49. Skilletfish
The skilletfish (Gobiesox strumosus) is a tiny, overlooked Bay resident that most anglers never notice — and that’s largely by design. These small, flattened fish use a specialized adhesive disc formed from modified pelvic fins to cling tenaciously to oyster shells, rocks, and hard substrate, remaining motionless even in strong tidal currents.
Skilletfish are dark brown to olive with a mottled pattern that blends seamlessly with oyster reef habitat. They rarely exceed 3 inches in length and have a broad, flattened head and a tapering body — the “skillet” shape that gives them their name. They feed on small crustaceans and invertebrates found on and around oyster reefs.
You’re most likely to encounter a skilletfish when sorting through an oyster cage or examining material pulled from a crab pot. They’re harmless, ecologically interesting, and completely dependent on healthy oyster reef habitat — making their presence a good indicator of reef health in Bay tributaries.
50. Naked Goby
The naked goby (Gobiosoma bosc) is another small but ecologically significant Bay resident found primarily in association with oyster reefs throughout the estuary. True to their name, naked gobies lack scales — their skin is smooth and bare — and they use the same type of fused pelvic fin disc as skilletfish to cling to hard substrate in current.
Naked gobies are typically 1.5 to 2.5 inches long with a brownish body marked by 8 to 10 pale bars. They’re among the most abundant small fish on Chesapeake Bay oyster reefs, where they spawn inside empty oyster shells and play an important role in the reef food web as prey for larger fish and wading birds.
Research has shown that naked gobies are sensitive indicators of oyster reef health — their abundance correlates directly with reef complexity and live oyster density. As the Bay’s oyster restoration efforts have expanded, naked goby populations in restored reef areas have responded positively, making them a useful ecological monitoring species.
51. Striped Blenny
The striped blenny (Chasmodes bosquianus) is a small, elongated fish found in the shallow, structured habitats of the Chesapeake Bay — particularly around oyster reefs, rocky jetties, and submerged debris. Blennies are perch-like in shape but lack scales, and they use their pelvic fins to prop themselves upright on hard surfaces, often sitting motionless while observing their surroundings.
Striped blennies have a distinctive pattern of horizontal blue-green stripes on a brown background, with breeding males displaying vivid blue facial markings and an orange-tipped dorsal fin. Most fish run 3 to 4 inches. They feed on small invertebrates, algae, and detritus found on and around hard substrate.
Like naked gobies, striped blennies are strongly associated with oyster reef habitat and are rarely encountered away from hard structure. They’re not a target species for anglers but are frequently observed by divers, snorkelers, and anyone examining oyster cages or reef material in the Bay.
52. Feather Blenny
The feather blenny (Hypsoblennius hentz) is the striped blenny’s close relative in the Chesapeake Bay, and the two species often share the same habitat on oyster reefs and rocky jetties. Feather blennies are distinguished by the prominent cirri — feather-like fleshy appendages — above their eyes, which give them an almost comically expressive appearance and provide the common name for the species.
Feather blennies are mottled brown to olive with irregular dark markings and typically run 3 to 4 inches in length. They’re slightly more tolerant of lower-salinity conditions than striped blennies and can be found further up Bay tributaries in brackish water. Like all blennies, they’re bottom-dwelling, structure-oriented fish that rarely venture far from their home territory.
Both blenny species are fascinating to observe in their natural habitat and serve as important indicators of nearshore habitat quality in the Bay. Their presence on oyster reefs, along with naked gobies and skilletfish, reflects a healthy, complex reef community.
53. Seahorse (Lined Seahorse)
The lined seahorse (Hippocampus erectus) is perhaps the most surprising fish on this list — yes, seahorses are fish, and yes, they live in the Chesapeake Bay. Found in the seagrass beds, dock pilings, and structured shallow-water habitats of the lower and middle Bay, lined seahorses are year-round residents that are more common than most people realize, though their cryptic coloration makes them exceptionally difficult to spot.
Lined seahorses range from 2 to 6 inches in height and display a remarkable range of colors — brown, yellow, orange, black, and gray — that they can adjust to match their surroundings. They anchor themselves to seagrass blades and dock structures with their prehensile tails, feeding on tiny crustaceans and zooplankton drawn in through their tube-like snout.
Key Insight: Male lined seahorses carry and give birth to live young in a specialized brood pouch — one of the animal kingdom’s most remarkable examples of male pregnancy. A single male can give birth to hundreds of tiny, fully formed seahorses in a single event.
Lined seahorses are not targeted by anglers and are protected from commercial harvest in many states. Their populations are sensitive to seagrass loss — a major ongoing issue in the Chesapeake Bay due to nutrient pollution and reduced water clarity. Protecting Bay grasses is directly tied to protecting seahorse habitat throughout the estuary.
The Chesapeake Bay’s fish diversity is one of its greatest assets — and one of its greatest responsibilities. From the striped bass that define the Bay’s angling culture to the lined seahorse hiding in a grass bed you might paddle right past, every species in this guide plays a role in the estuary’s complex, interconnected food web. Whether you’re fishing for sport, exploring by kayak, or simply curious about what lives beneath the surface, knowing these 53 species gives you a richer, more grounded understanding of one of America’s most important natural resources.
The Bay faces real pressures — nutrient pollution, habitat loss, invasive species, and changing water temperatures — but it also has a dedicated community of anglers, scientists, and conservationists working to protect it. The more you know about what lives here, the better equipped you are to be part of that effort. For a broader look at fishing techniques and gear that work across many of these species, exploring the full range of fishing rig setups is a practical next step before your next Bay outing.
