Abstract A mycological study of three major commercial bivalve species, Yesso scallop Mizuhopecten yessoensis, Pacific oyster Crassostrea gigas, and bay mussel Mytilus trossulus, from the coastal waters off Rikord Island (Peter the Great Bay, Sea of Japan) has been conducted. A total of 52 species of filamentous fungi from 19 genera of ascomycetes (and their anamorphic stages) and zygomycetes were isolated from shells and internal organs of the examined bivalves. Thirty-eight species (18 genera) of filamentous fungi were isolated from Yesso scallop, 21 species (eight genera) from Pacific oyster and 10 species (seven genera) from bay mussel. The studied bivalves showed a low degree of similarity in the diversity of the filamentous fungi. The identified filamentous fungi of the genera Aspergillus, Penicillium, Cladosporium, Chaetomium, etc. belong to a group of opportunistically pathogenic and toxigenic microorganisms that can cause mycoses and mycotoxicoses in aquatic animals.

Phenological Dates

Проанализированы многолетние изменения фенодат начала нереста и оседания приморского гребешка (Mizuhopecten (=Patinopecten) yessoensis Jay, 1857) в бухте Миноносок (зал. Посьета, зал. Петра Великого, Японское море) в 1970–2011 гг. Выявлен сдвиг среднемноголетних сроков нереста и оседания на более ранние даты. Рассчитана энтропия процессов. The long-term changes of the phenological dates of the Yesso scallop (Mizuhopecten (=Patinopecten) yessoensis Jay, 1857) spawning and settling onsets in Minonosok Inlet (Posiet Bay, Peter the Great Bay, East Sea/Sea of Japan) were analyzed in 1970–2011. It was found that the long-term average spawning and settling periods were moved to earlier dates. The entropy of processes was calculated.

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.

The sublittoral hermit crab Pagurus trigonocheirus (Stimpson, 1858) (Crustacea: Decapoda: Paguridae) is recorded from depths of 80–200 m along the continental coastline of the Peter the Great Bay, Sea of Japan. The exact sampling localities as well as photographs of live specimens are presented in the paper. Doubtful records of hermit crabs from the southern Russian coastline of the Sea of Japan are also discussed.
