AbstractDiscriminant function analyses of infection parameters of parasitic helminths revealed that abundances of seven helminth species contributed significantly to the delineation of four host populations of winter flounder Pleuronectes americanus from the central and southwest Scotian Shelf and the northeast Gulf of Maine (NAFO subdivision 4WX5Z). These were adult digeneans, Derogenes varicus, Genolinea laticauda, Steganoderma formosum and Steringophorus furciger, metacercariae of the digenean, Stephanostomum baccatum, and larval nematodes, Anisakis simplex and Hysterothylacium aduncum. The correct classification rate was 84% overall, with Georges Bank (5Z) and Sable Island Bank (4W) winter flounder being the most accurately classified samples at 98 and 88%, respectively. Winter flounder from southwest Nova Scotia (4X), an inshore sample from St Marys Bay and offshore fish from Browns Bank, had the lowest rates of correct classification (76 and 71%, respectively) due, primarily, to crossmisclassification between the two samples. Winter pairwise comparisons of four microsatellite markers identified significant genetic differences between all populations sampled with the Georges Bank population being the most genetically distinct overall, and St Marys Bay and Browns Bank fish being the least dissimilar.
