THE OCCURRENCE OF CIROLANA BOREALIS 



(ISOPODA) IN THE HEARTS OF SHARKS FROM 



ATLANTIC coastal WATERS OF FLORIDA 



Extensive depredation of catch triggered the 

 closing of the only large commercial shark fishery 

 on the Florida east coast (at Cape Canaveral) in 

 October 1978. Shark catches had been affected 

 throughout a 403 km stretch of nearshore waters 

 from St. Augustine to Fort Pierce, Fla., from 

 between 29 and 56 km offshore, at depths of 20-43 

 m. The organism responsible was a marine isopod, 

 Cirolana boreaUs (BowmanM. 



The presence of isopods (thought to be worms 

 by the fishermen) in the heart of a shark was dis- 

 covered in October 1977, when the pericardial
