NOAA Ecological Research on Hatchery-Cultured Blue King Crabs


In collaboration with AKCRRAB, the NOAA Alaska Fisheries Science Center in Kodiak plans to conduct blue king crab research using hatchery-cultured juveniles. Researchers will investigate the thermal tolerance, upper temperature threshold, and fine scale growth at elevated temperatures to help predict how wild blue king crab stocks will fare in the face of global climate change. Other avenues of blue king crab research using hatchery-cultured juveniles include predator-prey interactions and habitat requirements. To support this research, the Alutiiq Pride Shellfish Hatchery shipped over 12,000 juvenile blue king crabs to the NOAA Kodiak laboratory, which marks the largest single shipment by AKCRRAB to date.
