Morphological and ecological studies of Clavella adunca (Copepoda, Lernaeopodidae) on polar cod, Boreogadus saida
Clavella adunca (stroem, 1762) from the Barents Sea polar cod was studied. The general appearance and morphology of the appendages were similar to C. adunca f. iadda LEIGH-SHARPE, but the size of the trunk and cephalothorax were greater than those in other populations (mean trunk length 3.8 mm, widt...
