Comparatively few juveniles (386) were 

 captured with 11 species represented. Herring 

 were very numerous making up 73% of the 

 total catch of juveniles (Table 1). 



Areal Distribution 



Larval abundance increased with distance 

 from the Bay entrance (Fig. 5) and an analysis 

 of variance comparing catch means of all 

 larvae produced an F ratio 0.5871/0.0255 = 

 23.0235, with 4 and 44 df which was signifi- 

 cant at the 1% level. The comparatively large 

 catches from stations 4 and 5 were composed
