Figure 12.-Relation between surface temperature to menhaden 

 larval catch and sampling effort. 



tows were combined to compare the distribution of 

 catches by the shallow and deep nets. By the 

 shallow net, menhaden were taken in 138 tows and 

 by the deep net in 34 tows (Table 3). The distribu- 

 tion of catches was not significantly different in 

 the two nets {P >0.50). Comparisons of size of 

 larvae between day and night tows with the 

 shallow and deep nets showed no significant 

 differences.
