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 […]
Arctic cod is an important source of food for whales, seals, fish, birds, and humans in Arctic ecosystems. Arctic cod surviving to the juvenile stage were smaller and in poorer condition 5 months after embryonic oil exposure. Top fish experienced clean seawater whereas bottom fish was exposed to brief, low concentrations of dispersed oil during […]
New approach will deliver more timely, actionable data on changing ocean conditions. The Bering Sea is home to some of the nation’s largest and most profitable commercial fisheries, including Alaskan pollock and Pacific cod. It’s also one of the fastest warming parts of the world, with fish stocks becoming increasingly vulnerable to marine heat […]
