Abstract

For the first time the research focuses on studying the size and weight characteristics of the alien species in the Sea of Azov - bivalve mollusc Anadara kagoshimensis (Tokunaga, 1906). The relationship between allometric parameters of the mollusc (size and weight) were approximated by the power function. The maximal coefficient of determination is found for the power dependence of the total weight of the anadara on the width of the shell, with minimum coefficient of determination depending on the height of the shell. The maximum coefficient of determination is obtained for the power dependence of the raw weight of soft tissues of anadara on the length of its shell, with the minimum coefficient of determination depending on the width of the shell. The ratio of dry and raw weight of soft tissues is 0.16. Under comparison of the different environmental areas of anadara in the Black, Aenean seas and the Sea of Azov, the hatchery housing of mollusks in waters with moderate salinity is found to be the most favorable condition for their maximal growth.

亚速海外来双壳类软体动物鹿岛anadara kagoshimensis (tokunaga, 1906)的体型和体重特征

首次着重研究了亚速海外来物种——双壳类软体动物Anadara kagoshimensis (Tokunaga, 1906)的体型和体重特征。软体动物异速生长参数(尺寸和重量)之间的关系近似为幂函数。最大的决定系数是为阿纳达拉的总重量的权力依赖于壳的宽度，与最小的决定系数取决于壳的高度。得到了阿纳达拉软组织的原始重量对其壳的长度的幂依赖性的最大决定系数，与壳的宽度有关的最小决定系数。软组织干重与生重之比为0.16。通过对黑海、爱琴海和亚速海不同环境区域的比较，发现中等盐度水域的孵化场是软体动物最大生长的最有利条件。

期刊介绍： Russian Journal of Biological Invasions publishes original scientific papers dealing with biological invasions of alien species in both terrestrial and aquatic ecosystems and covers the following subjects:description of invasion process (theory, modeling, results of observations and experiments): invasion corridors, invasion vectors, invader species adaptations, vulnerability of aboriginal ecosystems;monitoring of invasion process (reports about findings of organisms out of the limits of natural range, propagule pressure assessment, settling dynamics, rates of naturalization);invasion risk assessment; genetic, evolutional, and ecological consequences of biological invasions of alien species; methods, means of hoarding, processing and presentation of applied research data (new developments, modeling, research results, databases) with factual and geoinformation system applications;use of the results of biological invasion research (methods and new basic results) under the study of marine, fresh-water and terrestrial species, populations, communities and ecosystems; control, rational use and eradication of the harmful alien species..
