ПЕРВЫЕ РЕЗУЛЬТАТЫ ВЫРАЩИВАНИЯ ТРИПЛОИДНОЙ ТИХООКЕАНСКОЙ УСТРИЦЫ CRASSOSTREA GIGAS В ЧЕРНОМ МОРЕ (ЮЖНЫЙ БЕРЕГ КРЫМА)

Growth processes of diploids and triploids of Pacific oysters, Crassostrea gigas, cultivated in the Black Sea, are examined. Absolute growth rates of shell of young diploids were 0,39 mm/days, weights of molluscs - to 17,3 mg/days, triploids – to 0,51 mm/days and 27,2 mg/days, accordingly, in summer months. Present differences in growth rates of molluscs with different ploidy are clearly defined during the first life months only, and then they are practically levelled. Relationship between height of shell and weight of molluscs is described by an allometric equation, regressive coefficients of triploids C. gigas are 2,180, diploid oysters - 2,389.
