[content id=”79272″] Using a combination of survey data and laboratory studies, NOAA Fisheries scientists identified starvation as the most likely cause of mass mortality event during the eastern Bering Sea marine heatwave. In 2022, the Alaska snow crab fishery was closed for the first time in history due to a sudden, dramatic decline in adult […]
Rapid and reliable age estimation is crucial for effectively and efficiently managing fish stocks. Scientists successfully used a novel technology, Fourier transform near infrared spectroscopy (FT-NIR)and artificial intelligence (AI), in combination, to more quickly produce reliable estimates of fish age. Otoliths are small calcified structures in the inner ear of a fish, also known as ear stones. […]
New survey estimate and recent trend data suggest the population may be stable and possibly increasing slightly. This month, NOAA Fisheries announced an updated abundance estimate for endangered Cook Inlet beluga whales. Scientists estimated that the population size is between 290 and 386, with a median best estimate of 331. In 2018, scientists estimated that the […]
Initial testing of seagoing drone was a success and planning is underway for sea trials during summer pollock survey in Alaska NOAA Fisheries is evaluating the use of cutting-edge technology that has the potential to improve acoustic-trawl surveys of walleye pollock, the largest U.S. fishery. The goal is to explore the use of uncrewed surface […]
