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.
