Abstract

The seasonal accumulation of the amnesic toxin domoic acid (DA) in the tissues of two commercial species of bivalves from Vostok Bay (the Sea of Japan) was assessed for the first time. The concentration of domoic acid in the tissues of the Pacific mussel Mytilus trossulus varied from 0.003 to 0.1 mg/kg during the period between October and February, and in the scallop Mizuhopecten yessoensis it varied from 0.003 to 0.09 mg/kg during the period between January and March. The maximum concentration of domoic acid in both species of mollusks was recorded in January. The results indicate the need for year-round monitoring of amnesic toxin concentrations in bivalves from Vostok Bay.

日本海沃斯托克湾1850年商品双壳菌Mytilus trossulus Gould和1850年Mizuhopecten yessoensis Jay记忆中的遗忘毒素（海藻酸）的季节性积累

摘要

首次评估了来自东方海（Vostok湾）（日本海）的两种双壳类双壳动物的记忆删除性毒素多摩酸（DA）的季节性积累。在十月至二月期间，太平洋贻贝Mytilus trossulus组织中的多摩酸浓度在0.003至0.1 mg / kg之间变化，在扇贝的Mizuhopecten yessoensis中，在一月之间在0.003至0.09 mg / kg之间变化和三月。一月份记录了两种软体动物中海藻酸的最大浓度。结果表明，需要全年监测沃斯托克湾双壳类中的遗忘毒素浓度。
