Phase 2 Expansion
Phase 2 adds Gulf of Alaska coverage and an at-a-glance genetic stock composition view so people can see how much bycatch comes from Western Alaska salmon systems.
Gulf Of Alaska Coverage
Area 610 — GOA East Yakutat
Shelf edge fishery interacting with mixed Gulf salmon stocks.
Chinook: 310 Chum: 3,520
Area 620 — GOA Central
Central Gulf trawl corridor between Kodiak and Prince William Sound.
Chinook: 420 Chum: 4,680
Area 630 — GOA West Kodiak
High vessel density west of Kodiak with overlap to salmon migration routes.
Chinook: 510 Chum: 6,240
Live vessel positions for these Gulf areas are available in the map region switcher.
Genetic Stock Composition
Stacked bars show the proportional origin mix for chum bycatch. Western Alaska share is highlighted because those fish are tied directly to Yukon and Kuskokwim food systems.
2015 W. Alaska 12%
2016 W. Alaska 14%
2017 W. Alaska 11%
2018 W. Alaska 9%
2019 W. Alaska 13%

Non-Alaska origin
Latest season in chart (2025) shows 17% Western Alaska origin fish in the sampled bycatch composition.
How To Use It
- Open the live map and switch between Bering Sea and Gulf of Alaska.
- Use vessel intel pages to connect movement to owners and operators.
- Use this genetic view when discussing how bycatch risk maps to river communities.
