Abstract
This paper analyzes the dynamics of occurrence of four sturgeon species from the family Acipenseridae (Russian sturgeon Acipenser gueldenstaedtii, sterlet A. ruthenus, stellate sturgeon A. stellatus, and beluga Acipenser (Huso huso) in IUU catches from the Ural (Zhaiyk in Kazakh) River in the Republic of Kazakhstan. Data on the arrested IUU catches of the annual quantity of sturgeons from 2012 to 2018 are given that demonstrate fluctuations in the amount of Ural River sturgeons from this river, as well as the male dominance in their populations. Biological parameters of Ural sturgeons (sex ratio, age, weight, length, and length–weight ratio) during the period of maximum catches in 2018 are given.
根据非法、未报告和无管制捕捞数据得出的哈萨克斯坦共和国乌拉尔河（斋伊克河）鲟鱼的生物参数
摘要 本文分析了从哈萨克斯坦共和国乌拉尔河（哈萨克语为Zhaiyk）非法捕获的鲟科四种鲟鱼（俄罗斯鲟Acipenser gueldenstaedtii、鲟A. ruthenus、星鲟A. stellatus和白鲟Acipenser (Huso huso)）的出现动态。报告提供了 2012 年至 2018 年期间每年鲟鱼非法捕获量的数据，这些数据显示了乌拉尔河鲟鱼数量的波动，以及鲟鱼种群中雄性占优势的情况。文中给出了 2018 年渔获量最大期间乌拉尔鲟鱼的生物参数（性别比、年龄、体重、长度和长重比率）。
