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 […]
These Arctic ice-bound seals are known for their unique appearance. An adult female ribbon seal (Histriophoca fasciata) rests on an ice floe in the Bering Sea.

New study provides critical insights into the Bering Sea snow crab population collapse in 2018–2019, offers hope for recovery, and provides a new tool for fisheries management. A new study addresses one of the largest mass mortality events in recent marine history—the abrupt collapse of the snow crab population in the eastern Bering Sea. The research team was led by […]
