The King George whiting fishery in Victoria, Australia, is based on sub-adult fish of 3 to 5 yr old in bays and inlets. Previously, Zonal Westerly Winds (ZWW) and the El Nino southern oscil- lation index (ENSO) cycle have been found to influence the larval stages and subsequent catches of some fishery species in southeastern Australia. Offshore spawning and long larval life, together with a fishery based on a few year classes of sub-adult fish, led to the hypothesis that the fishery would be strongly influenced by climatic conditions in the larval stage. A significant positive correlation was found between the strength of ZWW in the region and the catch 3 to 5 yr later. These conditions may have influenced larval transport rates, or alternatively may have led to increased plankton productiv- ity and therefore larval food supply. The ENSO cycle, however, was found to have a positive influ- ence on catch at 0 lag. This positive correlation suggested that La Nina conditions may have led to increased catchability of King George whiting. Post-larval abundances at a seagrass site in Port Phillip Bay were strongly correlated with ZWW, confirming that the effect of these winds occurred in the larval to post-larval stages. Overall, results suggest that climatic conditions exert a strong influ- ence on the larval to post-larval stages that subsequently affect the catch in the fishery.
