The 2013 to 2016 marine heatwave—known as “The Blob”—is the largest warm anomaly ever recorded in the North Pacific. In the Gulf of Alaska, scientists have connected low numbers of Pacific cod larvae, juveniles, and adults to loss of spawning habitat. This occured during and immediately following the heatwave. Compounding the ecological loss is the […]
Scientists and fishermen are working together to gain new insight into seasonal movements of valuable Pacific cod. Cutting edge technology and fishermen’s expertise are helping scientists track Aleutian Islands Pacific cod for the first time. Last winter scientists and fishermen partnered to launch a pilot study to develop methods for tagging cod on working commercial fishing […]
Pacific cod stocks hard hit by warming ocean temperatures are becoming a focal point at federal fisheries meetings, where harvesting sectors and processors fight over who gets to catch and process this versatile vitamin and protein packed white fish. Stock assessments in the fall of 2019 put the population of P-cod in the Gulf […]
Scientists simulated the Blob marine heatwave in the laboratory to assess the effects of past and future climate change on one of Alaska’s valuable commercial fish. Preliminary findings from a new laboratory study suggest that when ocean temperatures rise, lower fat prey leads to slower growth for juvenile Pacific cod. Scientists are evaluating how changes […]
