Daily rations of cod from the Barents Sea
Dolgov, Andrey V.; Yaragina, Natalia A.; Ajiad, Adnan Mosa; Mehl, Sigbjørn; Bogstad, Bjarte (PINRO-IMR Symposium, Conference object, 1992)Diurnal feeding rhythms and daily diets of the North-East Arctic cod were investigated based on data obtained at several stations made in the summer of 1988-1989. A well-pronounced feeding rhythmicity was recorded under ... -
