介绍了对黑海新的外来桡足动物 Pseudodiaptomus marinus 的微型浮游部分丰度动态的 3 年观测数据。季节性地，该物种的第一个幼体阶段出现在九月的塞瓦斯托波尔沿海水域。最大值在不同时间达到：从九月底到十一月底。然后丰度迅速下降。浮游生物中无节幼体和桡足类的存在表明，新的桡足类物种在黑海沿岸水域成功繁殖。入侵物种的总丰度值较低，最多不超过 10 000 ind。米–3。温度被认为是调节入侵物种丰度年际变化的主要因素之一。
The data of 3-year observations of the abundance dynamics of microplanktonic fraction of Pseudodiaptomus marinus—a new alien copepod for the Black Sea—are presented. Seasonally, the first juvenile stages of the species appeared in the Sevastopol coastal waters in September. The maximum values were reached at different times: from the end of September to the end of November. Then the abundance quickly dropped. The presence of nauplius and copepodites in plankton suggests that the new species of copepods successfully reproduces in the Black Sea coastal waters. The total abundance of the invasive species is characterized by low values, which do not exceed at maximum 10 000 ind. m–3. The temperature is assumed to be one of the main factors in the regulation of interannual variability in the abundance of the invasive species.
