The Food of Cod (Gadus callarias L.) of the 0-II-Group from deep Water in some Fjords of Northern Norway - With one Appendix - Oothrix borealis n. sp. - a bottom-dwelling Copedod from Northern Norway
MetadataVis full innførsel
An analysis has been made of the stomach contents of cod, chiefly of the 0-group, some also of the I-II groups from deep water in some fjords in North Norway during the years 1946-1949. The cod were all caught in the period August-November, except for single samples from March and May. The cod were found to feed almost exclusively on Euphausiacea, mainly Thysanoëssa inermis. In some places the Mysidacea were also important, chiefly Erythrops serrata and Michteimysis mixta. More locally other food species may be of importance, such as Decapoda (Pandalus borealis), Amphipoda (Rachotropis macropus and Halirages fulvocinctus, Isopoda (Eurycope cornuta), Copepoda (Calanus finmarchicus, Undinopsis similis, Harpacticoida), fish (Lumpenus maculatus and others). Decapoda and fish play a greater part as food of cod of the I-II groups than of the 0-group.
