Research confirms saxitoxin poisoning in seals and the presence of harmful algal species. In August 2025, two biologists from NOAA Fisheries’ Alaska Region Protected Resources Division traveled to St. George Island to conduct routine maintenance on NOAA facilities. Upon their arrival, they began receiving reports from residents about a high number of northern fur seals found […]
Energy deficiencies and inflammation may cause warming-related mortality in Pacific cod larvae. A new study used gene expression analysis to explore how temperature and ocean acidification affect Pacific cod larvae. Scientists discovered that larvae are equipped with genes that allow them to survive cool and acidified conditions. However, warming may cause mortality by […]
Scientists explored the effectiveness of shore-based observers in place of at-sea observers in a high-volume trawl fishery. They also developed a structured approach to evaluate shoreside monitoring programs in fisheries that lack at-sea human observers. NOAA Fisheries is required by law to monitor fishery catches to ensure sustainable management of U.S. fisheries. The Alaska pollock […]
