near the coast. The upwelLing conditions during fall and winter 

 1976 indicateu the possibility of a major intrusion of warm 

 southern water which could have extended beyond Point Conception. 



RELATION TO FISHERIES 



Within the coastal region from Point Conception (33N) to Cabo San 

 Lucas (2lN)x upwelling and upwelling related processes may be 

 important transport mechanisms for fish stocks which spawn in the 

 area.*' The five months of below normal indices in this region 

 followed a period of moderate upwelling at 30N/ 119W. On the 

 basis of above normal upwellinq at this location during peak 

 spawning/^ recruitment models predicted better than average 

 reproductive success for Pacific Tiackerel in 1976.' Relaxed 

 upwellinq during the fall and increased northward flow near the 

 coast would tend to favor northward transport of the southern 

 stock of Pacific mackerel/^ Scomber iaeonicus^ which would 

 increase the estimates of the 1976 year class above those 

 predicted on the basis of spring upwelling alone. Current market 

 evidence indicates that^ indeed^ the 1976 year class is much 

 stronoer than had been anticipated.*
