Hawaii fishing rules change with the fish, island, season and exact shoreline
Hawaiʻi does not work like a simple statewide bag-limit chart. A fish can be legal statewide but restricted inside a Marine Life Conservation District, Fisheries Management Area, Community-Based Subsistence Fishing Area or Public Fishing Area.
What matters right now on August 8, 2026
Moi
Statewide moi season is closed during June, July and August. The general open-season minimum is 11 inches with a 15-fish bag limit.
Spiny + slipper lobster
Ula and ula pāpapa are closed May through August. Additional size, sex, egg and method restrictions apply.
Kona crab
Pāpaʻi kualoa is closed May through September under the current statewide rule.
Waikīkī–Diamond Head
The Shoreline Fisheries Management Area is open during even-numbered years, making all of 2026 an open year, subject to its permitted gear and species rules.
Kōkeʻe rainbow trout
The 2026 season runs June 20–September 30, daily from 6 a.m.–6 p.m.
Pākuʻikuʻi
Current West Hawaiʻi Regional Fishery Management Area rules prohibit taking or possessing pākuʻikuʻi.
ʻAmaʻama
Striped mullet’s statewide closure is December–March, so the general statewide season is open in August.
Managed shoreline
MLCD, FMA, CBSFA, harbor and Public Fishing Area rules can be stricter than the statewide species table.
Six checks before taking marine life in Hawaiʻi
Oʻahu, Hawaiʻi Island, Maui County and Kauaʻi can have different local rules.
Check MLCD, FMA, CBSFA, harbor, refuge or Public Fishing Area boundaries.
Use the Hawaiian/local name and species identification, not appearance alone.
Moi, mullet, lobster, Kona crab and some local species have closures.
Minimum size and daily bag are separate tests.
Nets, spears, freshwater fishing and nonresident ocean fishing add another layer.
Hawaii closed seasons worth memorizing
General statewide minimum size when open: 11 inches.
General statewide open-season minimum: 11 inches. General bag limit: 15.
3¼-inch minimum carapace length. No spearing; female harvest prohibited.
2¾-inch minimum tail width. No spearing; egg-bearing animals protected.
4-inch minimum carapace length when season reopens. No spearing.
2026 announced season only; special trout rules apply.
Open January 1–December 31 in even-numbered years.
Several species use more restrictive local seasonal windows than the general statewide rules.
A local Fisheries Management Area or CBSFA may use a longer closure than the general statewide species rule. Always check both.
Hawaii regulated reef and nearshore fish limits
These are useful statewide starting points. Maui, West Hawaiʻi, Miloliʻi and other managed areas can impose stricter bag, size, season or no-take rules.
| Species | General statewide rule | What to check next |
|---|---|---|
| ʻAmaʻama — striped mullet | 11″ minimum; closed December–March. | Harbor/FMA rules can add aggregate or gear limits. |
| Moi | 11″ minimum; bag 15; closed June–August. | Some managed areas use longer local closures. |
| ʻŌʻio — bonefish | 14″ minimum. | Check local FMA/CBSFA take restrictions. |
| Manini — convict tang | 6″ minimum. | Newer live rule supersedes older 5-inch references. |
| Kole — goldring surgeonfish | 5″ minimum. | Miloliʻi uses an additional local season/bag rule. |
| Kala — horned unicornfish | Bag limit 4 per person per day. | Local areas may impose lower limits. |
| Uhu — parrotfish | Bag limit 2 total, all species. General minimum 10″; specified large uhu minimum 14″. | Maui and Miloliʻi have significant additional restrictions. |
| Kumu | 10″ minimum outside Maui. | Maui rule: 12″ minimum and bag limit 1. |
| Deep 7 bottomfish | Noncommercial combined bag limit: 5 per day. | Commercial fishing has separate license/reporting requirements. |
A one-inch mistake can turn a legal species into an illegal fish
Carry a rigid ruler or reliable measuring tape. Hawaiʻi rules use species-specific minimum sizes, and shellfish use completely different measurements such as carapace length, tail width or shell diameter.
Use the measurement method specified for the regulated species.
Minimum 3¼ inches carapace length.
Minimum 2¾ inches tail width.
Minimum 4 inches carapace length when open.
General statewide minimum: 1¼-inch shell diameter, or ½-inch meat diameter when meat only.
Marine invertebrates have their own size, sex and handling rules
| Marine life | Current general rule | Important restriction |
|---|---|---|
| Ula — spiny lobster | Closed May–August; 3¼” minimum carapace. | No spearing; whole/not mutilated; no taking or killing females. |
| Ula pāpapa — slipper lobster | Closed May–August; 2¾” minimum tail width. | No spearing; egg-bearing animals protected. |
| Kona crab | Closed May–September; 4″ minimum carapace. | No spearing. |
| Samoan crab | 6″ minimum width across the back. | No spearing; females may not be taken or killed. |
| Heʻe — octopus | 1-pound minimum. | Local CBSFA rules may set additional bag/method limits. |
| Sea cucumbers | Personal-use limit generally 10/person/day. | Commercial consumptive take and sale prohibited. |
| Limu / ogo | Home-consumption bag generally 1 lb/person/day. | Do not take the holdfast or reproductive material; special local limu rules exist. |
Four types of managed water every Hawaii angler should recognize
MLCD
Marine Life Conservation Districts can prohibit nearly all take of marine life.
Example: Hanauma Bay and Waikīkī MLCD use strict no-take rules.
FMA
Fisheries Management Areas can restrict gear, species, days, zones or methods.
Example: Waikīkī–Diamond Head alternates open and closed years.
CBSFA
Community-Based Subsistence Fishing Areas contain community-specific conservation rules.
Examples include Hāʻena and Miloliʻi.
Public Fishing Area
Freshwater PFAs can require licenses and impose special line, bait, bag and access rules.
Examples: Kōkeʻe, Wailua Reservoir and Wahiawā.

Waikīkī–Diamond Head is open this year — but only under its FMA methods
Even-numbered years are fishing years.
Odd-numbered years are closed to fishing.
From the Waikīkī War Memorial Natatorium area toward Diamond Head Lighthouse within the legal boundary.
Permitted during the 2026 open period
- Hook-and-line
- Thrownet
- Handnet used to land hooked fish
- Spearfishing, subject to time restrictions

Pākuʻikuʻi is still a no-take fish in the West Hawaiʻi Regional FMA
Where the rule applies
The West Hawaiʻi Regional Fishery Management Area runs along the west coast of Hawaiʻi Island from Ka Lae (South Point) to ʻUpolu Point and seaward to the State’s management boundary.
Current action
Do not take or possess pākuʻikuʻi within the Regional FMA. Other protected sharks, rays and marine species are also listed under West Hawaiʻi-specific rules.
Miloliʻi shows how a CBSFA can be stricter than the statewide table
| Species / method | Miloliʻi rule example |
|---|---|
| Kole | Closed March–June. July–February: minimum 5″, bag 20/person/day. |
| Pākuʻikuʻi | No take before July 1, 2027 under the current CBSFA framework. |
| Uhu ʻahuʻula / pālukaluka | Closed March–May. June–February: 14–20″, bag 1. |
| Uhu ʻeleʻele / uliuli | Take prohibited. |
| Other uhu | Maximum 3/person/day; only one may be terminal phase. |
| ʻOpelu zone | February–August, ʻopelu may be taken in the Traditional Management Zone only by hook-and-line. |
| Night spearing | Additional prohibitions apply, including night spearing of uhu. |
Nets and spears have statewide rules before local-area rules are added
Throw net

Hawaii saltwater and freshwater licensing are not the same
Recreational marine fishing
Hawaiʻi residents do not purchase the Nonresident Recreational Marine Fishing License for ordinary recreational ocean fishing.
A nonresident age 15 or older generally needs the Nonresident Recreational Marine Fishing License unless a listed exemption applies.
Freshwater game fishing
A Freshwater Game Fishing License is required to take introduced freshwater sport fishes.
7-day / 30-day.
Qualifying seniors age 65+ are listed as free. Online processing fees may apply.
Deep 7 bottomfish have a combined recreational bag limit
A person without a current Hawaiʻi commercial marine license may not take or possess more than a combined total of five Deep 7 bottomfish per day.
Count the Deep 7 species together rather than applying five to each species.
DAR currently states all former bottomfish restricted fishing areas are open.
Commercial marine licenses and reporting requirements are separate from recreational limits.
Some Hawaii waters prohibit fishing even when the fish itself is legal
Hanauma Bay MLCD
Fishing, taking or injuring marine life is prohibited. Possessing fishing-taking devices in the water is also restricted.
Waikīkī MLCD
This Marine Life Conservation District is different from the adjacent Waikīkī–Diamond Head Shoreline FMA. Fishing/take is prohibited in the MLCD.
Kahoʻolawe Island Reserve
Entry, boating, fishing and diving are prohibited unless specifically authorized by the Kahoʻolawe Island Reserve Commission.
Legal shoreline gear can become illegal inside a harbor
Kahului Harbor
Most nets prohibited except specified landing/hand nets. Maximum two poles with gear restrictions. Snagging prohibited.
Nāwiliwili Harbor
Nets generally prohibited except specified landing net. Snagging prohibited. Akule bag restriction applies.
Waimea Pier — Kauaʻi
Maximum two fishing poles/lines while on the pier. Thrownet possession and certain adjacent gear use are restricted.
Hilo / Wailoa
Special net, rod, crab, snagging and combined mullet/moi/ulua rules apply within the regulated area.
Hawaii pre-fishing regulation pack
- Save your exact fishing location: island, beach/bay, harbor, reef or reservoir.
- Open the DAR regulated-area map: make sure you are not inside an MLCD, FMA, CBSFA or refuge.
- Identify the exact species: Hawaiian common names matter because similar reef fishes can have different regulations.
- Check today’s season: especially moi, ʻamaʻama, lobster, Kona crab and local CBSFA species.
- Carry a measuring tool: know whether you need fish length, carapace length, tail width or shell diameter.
- Check gear at that location: thrownet, lay net, spear and rod rules can change by area.
- Visitors: nonresidents age 15+ should verify the recreational marine license before ocean fishing.
- Freshwater anglers: carry the Freshwater Game Fishing License and check PFA-specific rules.
Twelve Hawaii regulation mistakes that look harmless until enforcement checks
MLCD/FMA/CBSFA rules may completely change the answer.
General statewide closure runs June–August.
Spiny and slipper lobster are closed May–August.
Current closure extends through September.
Current statewide minimum is 6 inches.
Statewide and Maui/Miloliʻi regulations differ.
MLCD and Shoreline FMA are different management zones.
Nonresidents age 15+ generally need the marine recreational license.
General minimum is 2-inch stretched mesh.
General statewide lay-net rules prohibit unattended use.
Bass and tucunare are catch-and-release only in the PFA.
During the 2026 season, catch-and-release is prohibited; caught trout must be retained and count toward the seven-fish limit.
Need the license side before checking the catch limit?
Ask DAR a location-specific question
Statewide DAR contact listed by Hawaiʻi DLNR.
Mention island, bay/beach/harbor, species and fishing method.
Ask whether a local FMA/MLCD/CBSFA or temporary rule changes the statewide regulation.
“I’m fishing at [exact shoreline/bay/reservoir] on [date] and targeting [species] using [rod/thrownet/spear/etc.]. Can you confirm the current season, minimum size, bag limit, allowed gear and whether this spot is inside a specially regulated area?”
The rules are explained above; use these for the final official check
Fast answers to common regulation questions
Do Hawaii residents need a saltwater fishing license?
Hawaiʻi’s Nonresident Recreational Marine Fishing License applies to nonresidents age 15 or older, subject to listed exemptions. Hawaiʻi residents do not purchase that nonresident license for ordinary recreational ocean fishing, but all species, season, gear and managed-area rules still apply.
Do tourists need a Hawaii ocean fishing license?
Generally yes if they are nonresidents age 15 or older. Current nonresident recreational marine license options are $20 for one day, $40 for seven days and $70 annually, before any online processing charge.
Is moi fishing open in Hawaii in August 2026?
No under the general statewide rule. Moi is closed during June, July and August. The general open-season minimum is 11 inches and the general bag limit is 15, but local managed areas may impose stronger rules.
Can I catch lobster in Hawaii in August?
No under the general statewide rule. Spiny lobster and slipper lobster are closed from May through August. Additional size, sex, egg and no-spearing rules also apply.
What is the Hawaii uhu bag limit?
The current general statewide rule limits uhu to two total across all species per person per day. General minimum size is 10 inches, while specified large uhu use a 14-inch minimum. Maui and local managed areas can impose different restrictions.
Is fishing allowed at Waikiki-Diamond Head in 2026?
Yes within the Waikīkī–Diamond Head Shoreline Fisheries Management Area because even-numbered years are open years. Only permitted methods may be used, and spearing is prohibited from 6 p.m. to 6 a.m. The nearby Waikīkī Marine Life Conservation District is a separate no-take area.
What is the 2026 Kokee trout limit?
The 2026 Kōkeʻe rainbow trout season runs June 20 through September 30 from 6 a.m. to 6 p.m. The daily limit is seven trout per licensed angler. Catch-and-release is prohibited; all caught trout must be retained and count toward the bag.
Do I need a freshwater fishing license in Hawaii?
A Hawaiʻi Freshwater Game Fishing License is required to take introduced freshwater sport fish. Public Fishing Areas such as Kōkeʻe, Wailua Reservoir and Wahiawā also use their own local rules.
What size throw net is legal in Hawaii?
The general statewide minimum is two inches stretched mesh. Individual regulated areas may impose additional restrictions or prohibit throw nets entirely.
Can I fish anywhere along the Hawaii shoreline if the species is legal?
No. Marine Life Conservation Districts, Fisheries Management Areas, Community-Based Subsistence Fishing Areas, refuges, harbors and private-property access restrictions can prohibit or limit fishing even when the species itself is otherwise legal statewide.
Check the place before checking the fish
In Hawaiʻi, the exact fishing location can be just as important as species and size. Start with the island and management area, then confirm season, size, bag limit and gear before taking marine life.
