Salmon runs are notoriously variable: strong one year, and weak the next. New research shows that the same may be true from one century to the next.
Scientists in the past 20 years have recognized that salmon stocks vary not only year to year, but also on decades-long time cycles. One example is the 30-year to 80-year booms and busts in salmon runs in Alaska and on the West Coast driven by the climate pattern known as the Pacific Decadal Oscillation.
Now work led by University of Washington researchers reveals those decadal cycles may overlay even more important, centuries-long conditions, or regimes, that influence fish productivity. Cycles lasting up to 200 years were found while examining 500-year records of salmon abundance in Southwest Alaska. Natural variations in the abundance of spawning salmon are as large those due to human harvest.

NOAA recently published a proposed rule that would implement a traceability plan to help combat IUU fishing. The program would seek to trace the origins of imported seafood by setting up reporting and filing procedures for products entering the U.S.
The traceability program would collect data on harvest, landing, and chain of custody of fish and fish products that have been identified as particularly vulnerable to IUU fishing and fraud.Read more...
The following was released by the Maine Department of Marine Resources on Jan. 22:
The Maine Department of Marine Resources announced an emergency regulation that will support the continued rebuilding effort in Maine’s scallop fishery. The rule, effective January 23, 2016, will close the Muscle Ridge Area near South Thomaston and the Western Penobscot Bay Area.Read more...
