And of the lots of possible factors for this, a great deal of folks like to point a finger at the trawling market in the Bering Sea.
While that’s a subject for another day, there is some intriguing brand-new from Evan Erickson at Alaska Public Media that involves trawlers and king salmon. Presently, the fleets that trawl the Bering Sea for pollock run under a cap for the number of king salmon they can mistakenly capture (what’s called bycatch). According to Erickson, the pollock fleet “has actually stayed within the bounds of the cap presently in location for chinook bycatch [but] scientists are taking a look at methods to even more decrease the variety of the fish that get scooped up.”
However a scientist at the University of Alaska wishes to assist trawlers prevent king salmon as much as possible, so she’s utilizing pop-up satellite archival tags to assist acquire an understanding of precisely where king salmon relocation throughout the Bering Sea. This information, if it associates favorably with real-life experience, will assist trawl captains much better comprehend how to prevent king salmon bycatch.
