2021 Alaska Fisheries Science Center Groundfish Seminar Series - Donnie Arthur, Alaska Department of Fish and Game/UAF, CFOS
Counting yelloweye rockfish eggs from my couch and other reproductive findings from Prince William Sound and the northern Gulf of Alaska.
By using image analysis software and widely-accessible cameras, we generated rapid and accurate fecundity estimates for Yelloweye Rockfish, even when most laboratories were closed due to COVID- 19. These fecundity estimates allowed us to evaluate assumptions associated with spawning stock biomass, engage with stakeholder groups, and apply results to stock assessment models. We hope to add fecundity to the suite of estimation methods for many fish and invertebrate species, and facilitate more frequent monitoring of egg production.
