Helminth parasites as biological tags in population studies of Greenland halibut (Reinhardtius hippoglossoides (Walbaum)), in the north-west Atlantic
As part of a stock identification study, the parasite fauna of 608 Greenland halibut, Reinhardtius hippoglossoides (Walbaum) from six areas in the north-west Atlantic was examined. New records of parasite species for the Greenland area have been added by this study. No significant differences in pre...
