affected utilization by the fishery. The number 

 of marketable-size crabs affected effort and 

 catch per unit of effort. All three factors con- 

 tributed to increase in the 1 962 catchof Area 1; 

 the increase in the catches of Areas 2 and 3 re- 

 sulted primarily from improved market condi- 

 tions. 



ACKNOWLEDGMENT 



The cooperation of members of the crab 

 industry and of individual fishermen inmaking 

 catch and effort data available is gratefully 

 acknowledged.
