Catch limits for fishermen are often based on where fish have been most abundant in the past. But they have failed to keep up with geographical changes.

Had pus on them.

Kachemak Bay has witnessed massive die-offs of sea stars, murres and razor clams. Whats going on?

Around the state, biologists are unsure of what led to the lowest pink salmon harvest since the 1970s in a season that led Gov. Bill Walker to seek a disaster declaration from the federal government to bail out beleaguered pink fishermen. “We caught 39 million pinks this year,” said Forrest Bowers, the Commercial Fisheries Division director for the Alaska Department of Fish and Game. The department forecasted a harvest of 90 million fish between. Bowers said he had to comb records back to 1977 to find a year that bad.

Purse seiner crew scrambles to shovel the huge bycatch of Northern sea nettle jelly fish (Chrysaora melanaster) overboard.

“The exact reasons why the return fell at the lower end of the forecast range are unknown at this time, but poorer than average marine survival is a leading candidate.”
