Scientists identify key challenges and solutions for integrating environmental DNA into fisheries stock assessments. Environmental DNA (eDNA) is a valuable tool that can enhance fish stock assessments by providing a non-invasive, cost-effective, and scalable way to monitor fish populations. Challenges remain in fully integrating eDNA into stock assessment frameworks. But ongoing research and collaboration are […]
Testing confirmed widespread exposure of saxitoxin in marine mammals and other wildlife. New research establishes the first known link between the neurotoxin saxitoxin, accumulated during harmful algal blooms, and deaths of northern fur seals in the southeast Bering Sea. The study was published in the journal Marine Mammal Science. In the study, researchers collected and analyzed data from […]
Scientists teamed up to investigate how to best keep herring from spawning on kelp grown by ocean farmers in Alaska. Each spring, Alaska kelp farmers have the potential to run afoul of commercial herring fisheries when wild herring spawn in kelp farms. A new study helps evaluate different deterrents to prevent herring from spawning on their farms. This […]
Scientists find that Aleutian Island passes and the northern Gulf of Alaska remain key feeding grounds for this rare whale To locate endangered North Pacific right whales, scientists listen for their calls in Alaskan waters believed to be a part of their historical feeding grounds. To do this, scientists use underwater microphones, known as […]
