Abstract
Stomach contents from first-feeding larval sablefish (Anoplopoma fimbr ia) comprised mainly calanoid copepods. Along the west coast of Vancou ver Island, these copepods were the dominant zooplankton at the depth that sablefish larvae developed. We propose that strong year-classes i n sablefish populations occur when there is exceptional production of copepods. The periods of exceptional copepod production appear to be c orrelated with climate and ocean conditions.
