FISHERY BULLETIN: VOL. 78, NO. 2 



U.S. Atlantic shelf, the distribution of CaUinectes 

 is counter to the direction of immediate larval 

 transport. Recruitment to adult populations at the 

 northern limits of CaUinectes is problematical. 

 Not all larvae can originate from parental stocks 

 to the north. This may indicate that recruitment 

 takes place from megalopal populations closer in- 

 shore than those reported in this study and by 

 Nichols and Keney (1963), with the coastal boun- 

 dary layer possibly retaining larvae. The 

 megalopae collected farther offshore may repre- 

 sent larval wastage to parental populations (but 

 not necessarily to the species).
