Abstract

A total of 419 sablefish (Anoplopoma fimbria) was collected from 13 locations off Canada's west coast. Eleven of the stations were located on or near the continental slope, and two were located on seamounts. The fish were examined for prevalence and intensity of trematodes to determine the suitability of using these parasites as biological tags. The trematode fauna from the seamount sablefish was significantly different from that of slope sablefish, indicating that the seamount fish are distinct and separate stocks. Development of localized fisheries on these stocks could provide a significant yield to Canadian fishermen.
