The reproductive potential of northern rockfish (Sebastes polyspinis) and light dusky rockfish (S. variabilis) in the Gulf of Alaska was examined by measuring the success of oocyte and embryo development. The potential annual fecundity, reproductive failure rates, and relationships of these parameters to maternal size were examined. Both species have a seasonally synchronous reproductive cycle with parturition occurring in the late spring to early summer. Northern rockfish had a mean relative fecundity of 165.
