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.
