Hawaii Yellowfin tuna (ahi) 2026 — Season, Bag Limit, Size Rules
Thunnus albacares
Last updated
Yellowfin tuna — universally called 'ahi' in Hawaiian — anchors Hawaiʻi's blue-water pelagic sport + commercial scene. The deep-water Kona Coast (Big Island), the ʻAuʻau Channel (Maui–Lānaʻi), Penguin Bank (off Molokaʻi), and the Alenuihāhā Channel (Maui–Hawaiʻi Island) all hold dense ahi year-round, with practical peak in the late-spring through early-fall warm-water window (May – September) when offshore SST climbs above 78 °F. Hawaiʻi-caught ahi commonly range 30-100 lb on charter trolling tackle, with trophy 'shibi' fish (the Japanese-Hawaiian local term for ahi over 100 lb, increasingly used for fish over 200 lb in HI tournament culture) caught annually off Kona on heavy stand-up tackle. The IGFA all-tackle yellowfin tuna world record (427 lb, 2012, off Mexico's Magdalena Bay; HI state record ~290 lb). NO state size or bag limit applies to recreational ahi — federal Highly Migratory Species (HMS) rules under NOAA Western Pacific Regional Fishery Management Council govern any commercial sale; the recreational fishery is largely unrestricted but charter operators voluntarily release small fish. Standard trolling tackle is 50-130 lb conventional with skirted lures (Marlin Magic, Black Bart, Aloha Lures) at 8-10 knots over deep-water seamounts + current rips. NO recreational marine licence required.
