The plerocercus of Grillotia erinaceus as a biological tag for haddock Melanogrammus aeglefinus in the north sea and north‐east Atlantic
Analyses of the incidence and intensity of infestation with Grillotia erinaceus plerocerci in 8228 Melanogrammus aeglefinus indicate two distinct groups of haddock at Faroe, and three groups in the area to the north and west of Scotland. In the North Sea the following four groups were recognized: (1...
