The quantitative method of analysis offish feeding for the Barents Sea was first worked out at the Oceanographic Institute, and later applied to other bodies of water of the Union. Before this there had been only qualita- tive evaluations of the diet of fish in the Barents Sea. At present we have a fairly complete quantitative analysis of the feeding of cod, haddock, herring, caplin, launce, long rough dab, catfish and a series of abundant, non-com- mercial fish. V 4 S ?
