Forecast Information and Data Products for Tuna Fishers
Oregon and Washington’s commercial and recreational fishing fleets catch Pacific albacore tuna (Thunnus alalunga) in coastal areas from about July through November depending on the surface water temperatures. Most catches occur when sea surface temperatures range 16 to 18 C (60.8 to 64.4 ºF) (Beamish et al 2005) and sea surface chlorophyll-a concentrations range 0.2 to 0.4 mg m3 (Zainuddin et al 2008). NANOOS' Tuna Fishers App allows users to visualize where these conditions exist.
NOAA's FishWatch describes Pacific albacore tuna as a highly migratory fish species. This migration typically begins in the spring and early summer in waters off Japan, continues through the late summer into inshore waters off the U.S. Pacific coast, and ends in late fall and winter in the western Pacific Ocean. The timing and geographic extent of the albacore's migration in a given year is strongly influenced by ocean conditions.
Troll and pole-and-line albacore fisheries in U.S. and British Columbia waters are certified sustainable by the Marine Stewardship Council, (AAFA, WFOA, CHMSF), and are given a "Best Choice" rating by the Monterey Bay Aquarium's Seafood Watch Program and "Sustainable or Ocean Wise" by Canada's Ocean Wise Seafood Program. Below are links to data and information products that may be of interest to members of the albacore fishing community.
