Bass Fishing Regulations in Hawaii: What Every Angler Needs to Know
July 20, 2026
Bass fishing in Hawaii operates under a framework that surprises many visiting anglers from the mainland. Unlike most U.S. states, Hawaii treats bass as a strictly managed freshwater species — and the rules vary significantly depending on which reservoir you fish. Getting these details wrong can result in citations, confiscated fish, and fines.
This guide covers every layer of bass fishing regulations in Hawaii, from the species the state regulates and the waters where you can fish them, to size limits, bag limits, gear rules, and the licenses you need before you wet a line. Whether you’re a local angler or planning a trip to the islands, the information below will help you stay legal and fish with confidence.
Important Note: Hawaii fishing regulations are updated periodically by the DLNR Division of Aquatic Resources (DAR). The information in this article is based on the May 2025 Hawaii Fishing Regulations booklet published by DAR. Always verify current rules directly with the DAR before your trip, as regulations are subject to change.
Bass Species Covered by Fishing Regulations in Hawaii
Hawaii’s freshwater game fish rules cover two bass species that anglers commonly target across the state’s reservoirs. The first is largemouth bass (Micropterus salmoides), introduced to Hawaiian waters decades ago and now established in several reservoirs on O’ahu and Kaua’i. The second is the butterfly peacock bass, or tucunare (Cichla ocellaris), a tropical species also found in regulated public fishing areas.
Both species are classified as introduced freshwater game species, meaning a Freshwater Game Fishing License is required to target them, and it is unlawful to sell them. Hawaii does not have any native bass species — all bass present in the islands were introduced, which is a key reason the state manages them so carefully.
It is worth noting that largemouth bass, tucunare (peacock bass), and channel catfish all have specific limits under Hawaii’s freshwater regulations. You will encounter different rules depending on the specific water body you fish, so reading the reservoir-level details below is essential before you go.

Bass Fishing Season Dates and Closures in Hawaii
Hawaii does not operate a traditional open-and-closed bass season the way many mainland states do. Bass fishing in the state’s designated Public Fishing Areas (PFAs) is generally available year-round, but access is governed by area-specific rules and operating hours rather than a statewide seasonal calendar.
According to the DLNR fishing regulations, certain species of fish have different seasons, minimum sizes, and a limit on how many you can take. Certain regulated fishing areas also have different fishing periods and hours. This means you need to check the rules for each specific reservoir, not just the statewide summary.
One important closure to know: Nu’uanu Reservoir No. 4 is now closed to fishing. The remaining Nu’uanu reservoirs on O’ahu — Nos. 2 and 3 — fall within the Nu’uanu Freshwater Fish Refuge and require a permit from the Board of Land and Natural Resources to enter. Night fishing is prohibited at Wailua Reservoir on Kaua’i, where fishing is only permitted during the day.
Pro Tip: Many freshwater areas in Hawaii are on private land. Many marine shoreline and freshwater areas of the state are private property, and permission of the landowner is required for access. Always confirm land access before fishing a new spot.
Size Limits for Bass in Hawaii
Size limits for bass in Hawaii apply only at specific Public Fishing Areas. The rules differ by water body and by species, so the table below summarizes the key restrictions in effect as of the May 2025 DLNR regulations booklet.
| Water Body | Species | Minimum Size | Maximum Size |
|---|---|---|---|
| Wahiawā Public Fishing Area (O’ahu) | Largemouth Bass | Catch-and-Release Only | Catch-and-Release Only |
| Wahiawā Public Fishing Area (O’ahu) | Tucunare | Catch-and-Release Only | Catch-and-Release Only |
| Wailua Reservoir PFA (Kaua’i) | Largemouth Bass | 9 inches TL | 14 inches TL |
| Wailua Reservoir PFA (Kaua’i) | Tucunare | 12 inches TL | 15 inches TL |
At Wailua Reservoir, largemouth bass have a bag limit of 2 with a minimum size of 9 inches total length and a maximum size of 14 inches total length. Tucunare at Wailua carry a bag limit of 2, a minimum size of 12 inches total length, and a maximum size of 15 inches total length. These slot-style limits — where fish must fall within a defined size range to be kept — are designed to protect both juvenile fish and large, reproductively valuable adults.
At Wahiawā Reservoir (Lake Wilson) on O’ahu, there are no size limits to memorize for bass because bass and tucunare are catch-and-release only at the Wahiawā Public Fishing Area. It is unlawful to keep, retain, hold, or kill any bass or tucunare there, and any bass or tucunare brought to shore or on board a vessel must be returned to the water immediately.
Daily Bag Limits for Bass in Hawaii
Bag limits for bass in Hawaii depend entirely on which water body you are fishing. The statewide default rule — which applies to most reservoirs outside of designated Public Fishing Areas — is a strict catch-and-release requirement with no retention allowed at all.
For bass and tucunare across most Hawaiian waters, catch-and-release fishing is the only legal option. It is unlawful to keep, retain, hold, or kill any bass or tucunare, and any bass or tucunare brought to shore or on board a vessel must be returned to the water immediately.
The Wailua Reservoir Public Fishing Area on Kaua’i is the primary exception where limited retention is allowed. Bag limits at Wailua are listed per individual species, but an aggregate total bag limit of three fish applies. In practice, this means you could keep two largemouth bass and one tucunare in a single day, but you could not keep two of each species because that would exceed the three-fish aggregate cap.
Key Insight: The aggregate three-fish daily limit at Wailua Reservoir covers all regulated freshwater game species combined — not just bass. If you keep two largemouth bass, you have only one fish remaining in your daily aggregate, regardless of species.
For comparison with states that allow more liberal bass retention, see our articles on bass fishing regulations in Texas and bass fishing regulations in Louisiana.
Catch-and-Release Rules and Special Regulation Waters in Hawaii
Catch-and-release is not just a best practice in Hawaii — it is the law for bass in the vast majority of the state’s freshwater waters. Understanding which waters carry special rules protects you from violations and helps you plan your fishing trips accordingly.
The two primary designated Public Fishing Areas for bass are Wahiawā Reservoir (Lake Wilson) on O’ahu and Wailua Reservoir on Kaua’i. These are the only waters where bass fishing is formally permitted under a structured regulatory framework with published rules. Outside of these designated areas, most other freshwater bodies either prohibit bass fishing entirely or require landowner permission.
- Wahiawā Public Fishing Area (O’ahu): Bass and tucunare are catch-and-release only. No retention is permitted under any circumstances.
- Wailua Reservoir PFA (Kaua’i): Limited retention is allowed within the slot size limits and aggregate bag limit described above. No night fishing.
- Nu’uanu Reservoirs Nos. 2 and 3 (O’ahu): Bass and tucunare are catch-and-release only. It is unlawful to keep, retain, hold, or kill any bass or tucunare, and any fish brought to shore or on board a vessel must be returned to the water immediately. Entry requires a permit from the Board of Land and Natural Resources.
- Nu’uanu Reservoir No. 4 (O’ahu): Closed to fishing entirely.
Most reservoirs, stream banks, and even stream beds in Hawaii are privately owned. Unless these waters are officially designated as Public Fishing Areas, fishing is allowed only by special permission from the landowner. The state’s designated Public Fishing Areas include Koke’e and Wailua on Kaua’i, Wahiawā on O’ahu, and Waiākea on the Big Island.

Legal Gear and Bait Restrictions for Bass in Hawaii
Hawaii’s freshwater bass waters come with specific gear rules that differ by location. Violating gear restrictions is one of the most common compliance mistakes anglers make, so reviewing the rules for each water body before you fish is essential.
At the Wahiawā Public Fishing Area, the permitted gear includes hook-and-line fishing. You may fish with hook-and-line with not more than one lure or baited hook or two artificial flies attached to a single line, with only one line permitted on weekends and holidays, and two lines allowed on weekdays other than holidays. Attended traps and dip nets up to two feet in their longest dimension (excluding the handle) are allowed to land hooked fish or to take certain baitfishes, but tucunare, bass, channel catfish, and oscar may not be used as bait.
At the Wailua Reservoir Public Fishing Area on Kaua’i, the rules are slightly more restrictive. With a valid Freshwater Game Fishing License, you may fish using one pole and line, or one line with one lure or baited hook. A dip net up to two feet in its longest axis (excluding the handle) is allowed to land hooked fish.
Across all regulated freshwater areas, the following are prohibited:
- Snagging fish by any method
- Possession of firearms, air rifles or pistols, bows and arrows, spears, trotlines, nets other than dip nets, chemicals, or other illegal fishing gear
- Use of draw, drag, or seine nets
- Electrofishing devices and explosives in state waters
- Possession or use of electrofishing devices and poisonous substances in state waters
Treble hooks are banned in some reservoirs. Check the specific rules for your target water in the official DLNR regulations booklet before rigging up. Boats are permitted at Wahiawā Reservoir, but vessels exceeding 18 feet in length are prohibited, as are boats used for purposes other than fishing, boats traveling at speeds in excess of five miles per hour, and boats constructed of material other than wood unless provided with flotation to render the boat unsinkable.
Common Mistake: Using bass or tucunare as live bait is explicitly prohibited in Hawaii’s freshwater regulations. Always use legal baitfish species and confirm the bait rules for the specific water you are fishing.
Bass Fishing License Requirements in Hawaii
A Freshwater Game Fishing License is required to target bass in Hawaii’s public freshwater waters. It is unlawful for any person, except children below nine years of age, to fish, take, or catch any introduced freshwater game fish without first obtaining a license. Children exempt from the license requirement may still fish, provided they are accompanied by a licensed person.
As of May 2025, the Hawaii DLNR sets freshwater fishing license fees as follows:
| License Type | Fee (as of May 2025) |
|---|---|
| Resident Annual | $6 |
| Non-Resident Annual | $26 |
| 30-Day Tourist License | $11 |
| 7-Day Tourist License | $6 |
Freshwater Game Fishing License fees set by DLNR for 2026 are: Resident annual $6, Non-resident annual $26, 30-day tourist license $11, and a 7-day tourist license $6. There is a one-dollar convenience fee added to the price of any online license purchase.
In addition to the freshwater license, saltwater fishing for non-residents carries its own requirement. Since May 2, 2024, the State of Hawaii has required non-resident anglers 15 and older to obtain a valid fishing license for recreational marine fishing. The non-resident recreational marine fishing license fees are: 1-day $20, 7-day $40, and annual $70. Hawaii residents are exempt from the saltwater license requirement, and nonresident youth under age 15 can fish without licenses, as can active-duty military personnel and their families.
If you fish the Wahiawā Public Fishing Area, note that an additional entry permit is required beyond your fishing license. In addition to a valid Freshwater Fishing License, a separate entry permit is required for the Wahiawā Public Fishing Area (Lake Wilson). This permit will be emailed to you along with your license, and you must carry a completed copy of the permit when entering and fishing the area.
