CULTIVATION OF THE PACIFIC MUSSEL MYTILUS TROSSULUS (BIVALVIA: MYTILIDAE) IN MONO-AND POLYCULTURE IN THE NORTHERN PART OF THE SEA OF OKHOTSK

The growth of various size groups of mussels in the Veselaya Bay of the tauyskaya Bay, grown in mono - and polyculture in suspended cages in the sea, was analyzed. The maximum growth was observed in mussels of the size group 10-20 mm at the age of 2 years. Shellfish grew more slowly at the age of 3-5 years. The growth rate of mollusks of all size groups in the polyculture was higher than in the monoculture. The percentage of elimination of mussels of all age groups in the polyculture was significantly lower. The forecast of growth of mussels of various size groups in poly - and monoculture in suspended cages in the first, second and third growth seasons in Veselaya Bay is made. The efficiency of cultivation of mussels in the Northern part of the sea of Okhotsk together with other edible mollusks: makoma and Miya is shown.
