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.

Mussel Mytilus Trossulus

Mussels have evolved many adaptations to protect themselves, including the production of byssal threads. These are strong, proteinaceous fibres that mussels secrete to adhere themselves to rocks, preventing detachment by waves and predators. These byssal threads may be strengthened if mussels can recognize potential threats, such as native crabs, as their populations have a long history of coevolution. Unfortunately, the introduction of invasive predators poses a challenge for prey, which may not be capable of recognizing them. In this study, byssal thread production in the Pacific blue mussel (Mytilus trossulus ) was observed when exposed to effluent from the native red rock crab (Cancer productus) or the invasive European Green crab (Carcinus maenas). M. trossulus  were placed in closed systems with effluent from either C. productus , C. maenas  or control (no predator), over a 24-hour time period. Final measurements of number, length and diameter of byssal threads were recorded. M. trossulus  exposed to effluent from C. productus produced byssal threads at a statistically significantly faster rate than in the control group over the first 7.5 hours. M. trossulus exposed to effluent from C. maenas  produced byssal threads at a statistically significantly faster rate than both the C. productus and control groups. However, after 24 hours, there was no statistically significant difference between the mean number of byssal threads for any treatment. Additionally, we found no statistically significant difference between the mean diameter of byssal threads produced or length of byssal threads produced for any treatment.
