tion of stage V C. pacificus (474 copepods/m 3 ) was 

 found at the station adjacent to Point Conception. 

 The areas where C. pacificus showed the highest 

 abundances were located near regions of high chloro- 

 phyll a concentration. However, the abundances of 

 both C. pacificus stages were poorly correlated (al- 

 though significant at the 95% level) with chlorophyll 

 a over the entire grid (Table 4). 



Copepod Laminarinase Activity 



LA of female and stage V copepodites was much 

 higher than the levels of both euphausiid species 

 when expressed on a per weight basis. Like the 

 euphausiid results, there was large variability in the 

 LA of C. pacificus among stations. For example, LA 

 of stage V copepodites ranged from < 150 at offshore
