Исследована скорость роста культивируемых моллюсков подвесного выращивания в зал. Посьета (зал. Петра Великого, Японское море) за 1970–2011 гг. Приведены ростовые характеристики приморского гребешка (Mizuhopecten yessoensis (Jay, 1857)), тихоокеанской мидии (Mytilus trossulus Gould, 1850) и тихоокеанской (гигантской) устрицы (Crassostrea gigas (Thunberg, 1793)) в течение первых трех лет развития. Методами энтропийного анализа исследованы сроки достижения личинками и спатом определенных размеров. Выявлены временные интервалы и рассчитана вероятность наступления этих сроков. Обсуждается влияние техники культивирования на скорость роста. Ключевые слова: скорость роста, личинки, спат, приморский гребешок Mizuhopecten yessoensis, тихоокеанская мидия Mytilus trossulus, тихоокеанская устрица Crassostrea gigas, залив Посьета, Японское море. The growth rates of cultivated mollusks were studied in Possjet Bay (Peter the Great Bay, Sea of Japan) during 1970–2011. The growth characteristics were presented for the Yesso scallop (Mizuhopecten yessoensis (Jay, 1857)), the blue mussel (Mytilus trossulus Gould, 1850), and the Pacific (giant) oyster (Crassostrea gigas (Thunberg, 1793)) during the first three years of life. The average amount of time of the larvae and spat reaching certain sizes was determined using the method of entropy analysis. The time intervals were identified and the probability of these intervals to happen were also calculated. The influence of the cultivation techniques on the growth rate is discussed. Key words: growth rate, larvae, spat, Yesso scallop Mizuhopecten yessoensis, blue mussel Mytilus trossulus, Pacific oyster Crassostrea gigas, Possjet Bay, Sea of Japan.

AbstractThree nuclear DNA markers that diagnostically differentiate mussels within the Mytilus edulis complex (M. edulis, M. trossulus and M. galloprovincialis) are commonly used in taxonomic investigations: Glu5’, ITS and EFbis. As a rule, DNA extraction is performed before amplification. It is a time consuming process in the case of traditional methods based on chloroform and phenol extraction or relatively expensive using kits with ready spin columns. Moreover, DNA isolation from larvae is problematic, because of the small amount of tissue available. In this report we describe a simple, fast and inexpensive method of DNA extraction and gene amplification from larvae, spat and adults of the Baltic mussel Mytilus trossulus. The extraction method is adapted from that of Wang et al. (2006) and is based on digestion of tissue or whole animals in STE solution and direct gene amplification. On the basis of the results of routine analyses of mussels carried out in our laboratory we have concluded that the method we propose gives results that are consistent with standard methods, without requiring expensive reagents/equipment and is time saving.
