Abstract In this work, we present results of the first long-term oceanographic study of the mussel farm area in the brackish oligotrophic coastal waters off Sevastopol (Crimea, Black Sea). The long-term seasonal and annual variations of the thermohaline and main hydrochemical characteristics, their trends and probability distributions are reported. The variations of these parameters are determined mainly by the plankton metabolism and the polluted runoff. The coastal pollution is also a plausible reason for the statistical differences detected in the hydrochemical characteristics distributions on the mussel farm and at the background station. The obtained TRIX index values allow classifying the mussel farm area as the low-trophic region. The area under research is shown to be suitable in all parameters for the development of bivalve aquaculture.

2001-2018年塞瓦斯托波尔（黑海）近海贻贝养殖区温盐和水化学特征的长期变化

摘要 在这项工作中，我们展示了对塞瓦斯托波尔（克里米亚、黑海）近海的微咸贫营养沿海水域贻贝养殖区进行的首次长期海洋学研究的结果。报告了温盐和主要水化学特征的长期季节性和年度变化、趋势和概率分布。这些参数的变化主要由浮游生物代谢和污染径流决定。沿海污染也是贻贝养殖场和背景站的水化学特征分布中检测到的统计差异的合理原因。获得的 TRIX 指数值允许将贻贝养殖区归类为低营养区域。研究表明，研究区域的所有参数都适合发展双壳类水产养殖。
