gonad weight from body weight, generated the 

 length-weight relationships for each sex and tested 

 these between sexes. Again, differences between 

 sexes existed in southern California (ANOVA, F = 

 1 1.13, P < 0.01), but not in Monterey Bay (ANOVA, 

 F= 1.33, P> 0.05). 



Condition Factor 



Both male and female southern California white 

 croaker displayed differences in condition between 

 peak spawning and resting seasons (Table 5). In both 

 sexes, fish were more robust during the resting 

 season, perhaps because energy normally utilized for 

 somatic maintenance and growth was shifted to egg 

 and sperm production and spawning behavior. Over 

 all seasons, whereas southern California females 

 were more robust than males (Table 5), no such sex-
