Data from the research of the Pribilof Islands blue king crab (Paralithodes platypus) recruitment limitation as a potential bottleneck to rebuilding from overfished status, Saint Paul Island, 2017-2019
This project conducted nearshore field studies on Saint Paul Island from 2017-2019 and investigated larval supply, habitat availability, and predation on juveniles as potential factors limiting recruitment and to inform future rebuilding efforts. It quantified larval supply with settlement collector...
