Spearfishing Laws in Hawaii: What You Need to Know Before You Dive
July 15, 2026
Hawaii’s underwater world is one of the most biodiverse marine environments on the planet, making it a top destination for spearfishers across the United States. The Hawaii Division of Aquatic Resources (DAR) publishes fishing regulations that are current as of May 2025 and subject to change. That last part matters — spearfishing laws in Hawaii are more layered than most states, covering everything from the gear you can carry to the specific hours you’re allowed in the water.
Whether you’re a local heading out to a familiar reef or a visitor planning your first dive, knowing the rules protects both you and the marine ecosystem you’re exploring. The regulations are designed to acquaint sport and commercial fishermen with state laws and rules, but they are not a legal document, and failure to include complete statutes does not relieve anyone from abiding by those statutes and rules.
This guide walks through every major area of Hawaii spearfishing law — from licenses and legal species to no-go zones and the penalties officers can impose on violators. You can also compare how Hawaii’s approach differs from other states by reading about spearfishing laws in Florida and spearfishing laws in Texas.
Is Spearfishing Legal in Hawaii?
Yes, spearfishing is legal in Hawaii and very popular. The state has a deep cultural connection to ocean fishing, and spearfishing has been practiced in Hawaiian waters for generations. However, legal does not mean unrestricted — the rules governing where, when, how, and what you can spear are detailed and actively enforced.
The jurisdiction of Hawaii spearfishing regulations falls under the Department of Land and Natural Resources (DLNR). These rules apply to all spearfishing activities conducted within the state’s coastal waters, including both residents and visitors. The DAR handles the science and rulemaking side, while the Division of Conservation and Resources Enforcement (DOCARE) handles on-water enforcement.
The provisions apply to all areas of the state, unless exempted or modified for certain specific management areas. That exemption clause is important — some of the most popular dive spots in Hawaii are inside management areas with their own additional restrictions that go beyond the statewide baseline.
Pro Tip: Before any dive trip, download the current Hawaii Fishing Regulations booklet directly from the DLNR Division of Aquatic Resources website. Rules are updated periodically and vary by island and management area.
Freshwater vs. Saltwater Spearfishing Rules in Hawaii
The divide between freshwater and saltwater spearfishing in Hawaii is significant, and the two environments operate under entirely different frameworks. Most of what people picture when they think of Hawaiian spearfishing — reef fish, open ocean pelagics, and coral environments — falls under the saltwater rules. Freshwater spearfishing is a much more restricted activity.
A Freshwater Game Fishing License is required for the taking of certain introduced freshwater fishes. Beyond the licensing requirement, spearing in freshwater is tightly constrained. It is unlawful to spear any crustacean (except introduced freshwater prawn), turtle, or aquatic mammal at any time. This prohibition applies in both fresh and saltwater environments statewide.
In freshwater, spearing is generally not a recognized legal method for most species. Bass and tucunare are subject to catch-and-release fishing only, and it is unlawful to keep, retain, hold, or kill any bass or tucunare. The introduced freshwater prawn is one of the few exceptions where spearing is permitted in freshwater. For saltwater, the rules are more permissive but still carry significant area-by-area restrictions.
Important Note: Hawaii’s freshwater fishing areas are often located on private land. Fishermen are advised that many marine shoreline and freshwater areas of the state are private property, and that permission of the landowner is required for access. The fishing regulations publication does not imply or endorse the public’s right to enter into or fish in such areas.
License and Permit Requirements for Spearfishing in Hawaii
One of the most common questions from visitors is whether Hawaii requires a spearfishing license. The answer depends on your residency status and whether you plan to fish commercially or recreationally.
Recreational spearfishers do not need a license to fish in ocean waters. However, this does not exempt them from knowing and following all other regulations that apply to spearfishing in Hawaii. So while Hawaii residents can spearfish in saltwater without a recreational license, every other rule — species restrictions, gear rules, area closures, bag limits — still applies in full.
If you are a nonresident, you will need to obtain a Nonresident Recreational Marine Fishing License (NRMFL). If you’re visiting from out of state, you’ll need to purchase a saltwater fishing license. There are daily, weekly, and annual options, and they’re pretty affordable. Licenses can be purchased through the DLNR website or at authorized vendors such as local tackle shops.
| Fisher Type | License Required? | License Type |
|---|---|---|
| Hawaii resident (saltwater) | No | N/A — no recreational saltwater license required |
| Non-resident (saltwater) | Yes | Nonresident Recreational Marine Fishing License (NRMFL) |
| Any angler (freshwater game fish) | Yes | Freshwater Game Fishing License |
| Commercial spearfisher | Yes | Commercial Marine License (CML) |
Commercial spearfishers must obtain a Commercial Marine License (CML) to legally sell their catch. The process for obtaining a CML involves submitting an application to the DLNR, along with the required fee. Recreational anglers should not sell their catch — for that, you need a commercial marine license.
Legal Species and Prohibited Species for Spearfishing in Hawaii
Hawaii has a rich mix of legally targetable reef and pelagic fish alongside a firm list of species you cannot spear under any circumstances. Knowing the difference before you enter the water is not optional — it’s a legal requirement.
Among the popular legal targets, yellowfin tuna (Thunnus albacares) — known locally as ahi — are a prized spearfishing quarry. Mahi-mahi (Coryphaena hippurus), various trevally species including giant trevally (Caranx ignobilis), and reef fish like uhu (parrotfish) are also commonly pursued, though parrotfish carry specific bag limit restrictions detailed in the next section.
It is unlawful to take, kill, possess, sell, or offer for sale any specimen of the following: Hawaiian stingray, broad stingray, pelagic stingray, spotted eagle ray, blacktip reef shark, gray reef shark, whitetip reef shark, tiger shark, whale shark, horned helmet, and Triton’s trumpet. These protections apply statewide and are not limited to specific management areas.
Hawaii spearfishing laws prohibit the take of certain fish, marine mammals, and other marine life. This includes endangered species, species that are critical to the ecosystem, or those that are protected for cultural reasons. Hawaiian monk seals and sea turtles are protected under both state and federal law. Accidentally hooking or disturbing a protected species can create serious legal problems, even without intent. Several species in Hawaiian waters are shielded by both federal and state law, and the penalties are steep.
It is also unlawful to spear any crustacean (except introduced freshwater prawn), turtle, or aquatic mammal at any time. This means lobster, crab, and shrimp cannot be taken by spear regardless of location or season. If you’re unsure whether a species is protected, the DAR’s Marine Fishes and Other Vertebrates list is the authoritative reference.
Key Insight: Herbivore fish like tangs, surgeonfish, and parrotfish play a critical ecological role in Hawaii. These fish prevent algae from growing out of control and smothering the reef. Removing too many herbivores can upset the ecosystem’s balance and contributes to local declines in coral reef health. Several management areas restrict or ban the take of these species specifically.
Gear Restrictions for Spearfishing in Hawaii
Hawaii imposes some of the most well-known gear restrictions in U.S. spearfishing law, and the SCUBA rule is the one that catches the most people off guard. Understanding what equipment is and isn’t allowed can save you from a citation before you even pull the trigger.
It is unlawful to engage in SCUBA spearfishing, possess both SCUBA gear and a spear at the same time, or possess SCUBA gear and any specimen of speared aquatic life at the same time. This is a statewide baseline rule. You should also be aware that you won’t be allowed to spearfish using SCUBA gear on the west side of the island of Hawaii. The West Hawaii restriction is an additional island-specific prohibition that goes beyond the general SCUBA rule.
Generally, the entire west coast (also called the Kona Coast) of the Big Island prohibits spearfishing while using SCUBA gear, whether day or night, all along that shoreline. Free diving and breath-hold diving with a speargun or Hawaiian sling remain the legal methods throughout the state.
Nighttime spearfishing is another major gear-adjacent restriction. It is unlawful to use any spear between the hours of 6:00 PM to 6:00 AM. This rule applies in Fisheries Management Areas and certain other managed zones. DLNR officials identified night spearfishing as a major threat to fisheries and considered a nighttime ban a simple solution that wouldn’t impact too many fishers but could make a big difference.
- SCUBA spearfishing is prohibited statewide as a baseline rule
- SCUBA spearfishing is additionally banned along the entire Kona Coast of Hawaii Island
- Spearing between 6:00 PM and 6:00 AM is prohibited in managed areas
- Spearguns, Hawaiian slings, and pole spears used while free diving are the legal gear types
- Firearms may not be used to take fish, crustaceans, or marine mammals, with narrow exceptions for tuna and billfish already gaffed, and sharks
For a comparison of how gear rules differ in other states, see spearfishing laws in Michigan and spearfishing laws in Virginia.
Off-Limits Areas and No-Spearfishing Zones in Hawaii
Hawaii has one of the most extensive networks of marine protected areas in the United States, and navigating them is one of the more complex parts of spearfishing legally in the state. There are numerous marine protected areas (MPAs), conservation districts, and sanctuaries where spearfishing is either prohibited or heavily restricted. These areas are usually marked with signs, buoys, or other markers, but it’s important to know their locations beforehand.
Spearfishing is fair game in most areas, but some spots are totally protected. Marine Life Conservation Districts (MLCDs) — places like Hanauma Bay on Oahu — are areas where fishing, including spearfishing, is completely off-limits. Hanauma Bay is one of the best-known MLCDs. Fishing of any kind is prohibited there, as is possessing any device in the water that could be used for taking marine life.
Beyond MLCDs, Hawaii also designates Fish Replenishment Areas (FRAs), Fisheries Management Areas (FMAs), and Community-Based Subsistence Fishing Areas, each with its own specific rules. Within any Fish Replenishment Area, Marine Life Conservation District, or Fisheries Management Area, it is unlawful to collect aquatic life without a permit.
The Northwestern Hawaiian Islands are part of the Papahānaumokuākea Marine National Monument, where recreational fishing, including spearfishing, is highly regulated and generally requires a permit. This area covers a vast stretch of ocean northwest of the main Hawaiian Islands and is one of the most protected marine environments in the world.
Notable no-spearfishing or heavily restricted zones include:
- Hanauma Bay MLCD (O’ahu) — all fishing prohibited
- Pūpūkea MLCD (O’ahu north shore) — all marine life take prohibited
- Waikīkī-Diamond Head Shoreline Fisheries Management Area — spearing prohibited 6 PM–6 AM
- Maunalua Bay FMA (O’ahu) — nighttime spearfishing banned as of 2025
- Kahekili Herbivore Fisheries Management Area (West Maui) — herbivore fish take prohibited
- Papahānaumokuākea Marine National Monument — permit required for any take
- Hawaii Marine Laboratory Refuge (Kāne’ohe Bay) — all aquatic life take unlawful
Maunalua Bay’s new rules establish a Fisheries Management Area that stretches from Kawaihoa Point to a buoy just off the Diamond Head Lighthouse. This area was added in 2025 following a community-led conservation effort. See also Hawaii’s dolphin interaction laws for related marine wildlife restrictions that apply in the same waters.
Bag Limits and Size Limits for Spearfishing in Hawaii
To ensure sustainable fishing practices, Hawaii spearfishing laws impose catch limits. These limits restrict the number of fish you can take in a given time period, usually per day. The catch limits vary depending on the species of fish, so it’s essential to familiarize yourself with the specific limits for the fish you’re targeting.
Size limits ensure that fish are allowed to reach reproductive size before being harvested. Closed or limited fishing areas enable fish to grow and spill over into adjacent, open fishing spots. Closed seasons ensure that fish are not captured during their breeding season. These three tools — size limits, area closures, and seasonal closures — work together in Hawaii’s management system.
According to the Hawaii DAR’s fishing regulations (as of May 2025), noncommercial fishers face a daily bag limit of 20 fish total across all regulated species. Moi has a closed season from June through August to protect spawning, and outside that window the minimum size is 11 inches. Parrotfish (uhu) carry specific restrictions — being in possession of more than two uhu (parrotfish) is a violation in certain Fisheries Management Areas.
| Species / Category | Key Restriction | Notes |
|---|---|---|
| Moi (Pacific threadfin) | 11-inch minimum; closed June–August | Closed season protects spawning |
| Uhu (parrotfish) | Bag limit restrictions in FMAs | Max 2 in some managed areas; no spearing in certain zones |
| All regulated species (noncommercial) | 20 fish per day aggregate | Per DAR regulations as of May 2025 |
| Sea cucumbers | 10 per person per day (personal use) | Commercial take and sale prohibited |
| Lobster / crustaceans | No spearing permitted | Hand harvest only during open season; females prohibited |
The size and bag limits for various fish species are determined based on their reproductive cycles and population status. Adhering to these limits is not just a legal requirement but a contribution to the sustainability of Hawaii’s marine life. The DAR updates these numbers as conditions change, so checking the current year’s regulations booklet before each trip is worth the effort. For a broader look at how bag limits work in other states, see spearfishing laws in Indiana and spearfishing laws in New Jersey.
Penalties for Spearfishing Violations in Hawaii
Hawaii enforces its spearfishing laws through DOCARE, and the consequences for violations range from civil fines to criminal charges. Enforcement is conducted by the Division of Conservation and Resources Enforcement (DOCARE) and local law enforcement agencies. Regular patrols in popular spearfishing areas ensure compliance with DLNR rules.
Those caught breaking the rules face either civil or criminal penalties, depending on the severity of the violation. Civil violations start with a fine of $1,000 on the first offense and go up from there. Real-world enforcement confirms these penalties are applied. One case involved a man spearfishing at the Waikiki Fisheries Management Area around 10 PM — not only was he spearfishing during prohibited times, but he was also in possession of more than two uhu and fish that were too small to be legal. A total of 73 fish were confiscated from him.
Beyond fines and confiscation, violations can escalate significantly. Equipment used in illegal spearfishing activities may be confiscated by enforcement officers. Serious violations may lead to criminal charges, which can result in a permanent record and further legal repercussions.
The penalty structure for spearfishing violations in Hawaii includes:
- Civil fines starting at $1,000 for a first offense in managed areas
- Escalating fines for repeat or more serious violations
- Confiscation of spearfishing gear and catch
- Criminal charges for severe violations
- Potential loss of fishing privileges
Ignorance of these regulations is not accepted as a defense in the event of enforcement actions. If you have questions about a specific area or rule, contact the nearest office of the Division of Aquatic Resources (DAR) or the Division of Conservation and Resources Enforcement (DOCARE).
Hawaii’s enforcement approach reflects the state’s broader commitment to marine conservation. Hawaii’s spearfishing regulations are subject to periodic review and updates. Recent changes include increased protection for endangered species with stricter penalties for violations, and certain areas have been newly designated as no-fishing zones to help preserve marine ecosystems. Staying current with the DAR’s regulations booklet — updated as recently as May 2025 — is the most reliable way to stay on the right side of the law.
