It is seen that the commercial fleet concentrated its fishing to a very restricted 

 portion of the bank with the maximum effort in both summer and spring being expended 

 in subarea J. The weighted catch per tow and percen':age age -composition of the 

 census data and the catch per day and percentage age -composition of the commercial 

 fleet is presented in table 18 .
