Scientists are able to evaluate more data in less time to support sustainable Alaska Fisheries. Scientists demonstrate that an innovative technology to scan fish otoliths (ear stones) coupled with trained computer models can determine rockfish ages as well as humans, and even more quickly. This technology, Fourier-transform near-infrared spectroscopy, examines the unique vibrations of molecules […]
Radiocarbon Dating Techniques Used to Estimate Ages. In a new project, scientists hope to learn more about age determination and maximum lifespan of Pacific sleeper sharks. Scientists are examining the nuclear core and outer eye lens layers of this species to estimate plausible age ranges. Results of this study may offer valuable information to […]
Community support key to removing a plastic packing band from sea lion’s neck. For the second year in a row, three experts successfully freed an entangled Steller sea lion in Kodiak. NOAA Fisheries’ Kim Raum-Suryan and Alaska Department of Fish and Game’s Lauri Jemison, along with veterinarian Dr. Kate Savage, had been here before. In 2023, […]
