<p>The three copepod species Clavella perfida (Lernaeopodidiae), Haemobaphes diceraus (Pennellidae), and Beringobdella rectangulata (Piscicolidae) parasitize the gills of the Alaska pollock, Gadus chalcogrammus (Gadidae). Parasite specimens were sampled from Alaska pollock collected from the Shiranuka and Shibetsu areas of Hokkaido, Japan and the eastern Bering Sea. We investigated whether each of the three parasitic copepod species are panmictic across sampling locations by comparing the nucleotide sequences of the mitochondrial COI gene. The occurrence of B. rectangulata was rare in this study (n=1 from Shibetsu only) and therefore excluded from the analysis. Our analyses revealed no genetic differences among the three sampled populations of C. perfida and H. diceraus. We conclude that these latter two parasitic copepods are widely distributed in the North Pacific and represent panmictic populations.</p>
