CHEMICAL COMPOSITION AND ENERGY CONTENT OF PACIFIC SALMONS IN THE OKHOTSK SEA

Abstract

The main bioenergetic parameters of pacific salmons are presented on the data obtained in marine expeditions in 2003–2015. Among the examined species, the minimum energy content is registered in the muscle tissue of chum salmon and pink salmon, and the maximum energy content — in the muscles of king salmon. Total amount of the energy accumulated by juvenile pink salmon during its life within the Okhotsk Sea is estimated as 532 kcal or 27 % of the total energy accumulated in the whole marine period of its life, for juvenile chum salmon this amount is 492 kcal (11 %). The rest is accumulated by adults during their feeding in the ocean: pink salmon, without ranking by age and sex, gains in the North Pacific on average 1 442 kcal or 73 % of the total energy accumulated in the marine period of life, chum salmon — 4 071 kcal (89 %).
