Accurate age estimates are vital to conservation efforts for Cook Inlet belugas, which were listed as endangered following a significant population decline in […]
For more than two decades, Alaska has led the way in using ecosystem information to inform resource management decisions.

This may be the first time data collected using uncrewed surface vehicles were used to help produce an annual estimate of abundance for a commercial fish stock. Every other year, NOAA Fisheries conducts an acoustic-trawl survey from crewed research vessels to measure pollock abundance in Alaska’s eastern Bering Sea. As a result of COVID-19, many […]
