Abstract

The density and biomass of aggregations of the clam Mya uzenensis have been studied in four areas of the littoral zone in Taui Bay. Aggregations of this bivalve species were mosaically distributed in the form of beds from 0.5 to 5.0 m² in size. On suitable sediments, Mya aggregations occupied 25–40% of the littoral zone area. The structure of aggregations in the littoral zone of Ola Liman and Veselaya Bay, formed by clams with a shell size of 22.1–91.1 mm and ages of 2–14 years, is characterized as stable. A study of the allometric shell growth has shown age-related variations in the correlation of proportions, which level out after 10 years of age. The stock of M. uzenensis in the study areas of the littoral zone has been estimated. Thus, an annual landing of 158.4 t of clam can be recommended with a harvest level of 7% of the commercial stock.

鄂霍次克海Taui湾沿岸地区各部分的异速生长模式和Mya uzenensis（Bivalvia：Myidae）聚集体结构

摘要

在Taui湾沿岸带的四个区域，研究了Muzuzuzensis蛤的聚集体的密度和生物量。该双壳类物种的聚集体以大小从0.5到5.0 m ²的河床形式镶嵌分布。在合适的沉积物上，Mya聚集体占据了沿海区面积的25–40％。Ola Liman和Veselaya湾沿岸带聚集体的结构是稳定的，其蛤壳大小为22.1-91.1 mm，年龄为2-14岁。对异速成壳生长的研究表明，年龄相关的比例相关性变化在10岁后趋于平稳。uzenensis的股票在沿海地区的研究地区的估计。因此，可以建议每年捕捞158.4吨蛤，收获量为商品种群的7％。
