Scientists, politicians, managers, and Tribes try to find common ground on Western Alaska salmon crash
On Dec. 8 and 9, U.S. Sens. Lisa Murkowski and Dan Sullivan and Rep. Don Young held a Zoom meeting between salmon researchers, tribes, and managers. Their goal was to unite these groups’ efforts to determine the cause of the ongoing Chinook declines and the sudden chum crash in Western Alaska. After two days of meetings, the groups are still at odds over what’s causing the declines, and what the best way to move forward is.

B.C. fish farms transmit virus to endangered wild Pacific salmon, new study confirms
One common salmon virus introduced to southern B.C. 30 years ago despite assertions from government, industry virus is 'endemic' to province. Further analysis of the PRV genomes in B.C. waters indicate that the number of PRV infections in the region has increased by two orders of magnitude over the last two decades, a pattern that aligns with the regional growth in farms, where nearly all of the fish become infected.

Weak winds in the Pacific drove record-breaking 2019 summertime marine heat wave
Weakened wind patterns likely spurred the wave of extreme ocean heat that swept the North Pacific last summer, according to new research led by the University of Colorado Boulder and the Scripps Institution of Oceanography at the University of California San Diego. The marine heat wave, named the "Blob 2.0" after 2013's "Blob"; likely damaged marine ecosystems and hurt coastal fisheries. Waters off the U.S. West Coast were a record-breaking 4.5 degrees F (2.5 degrees C) above normal, the authors found.
