Abstract

The size–age structure and growth of the Sardine Cisco Coregonus sardinella, the Siberian Whitefish C. lavaretus pidschian, and the Broad Whitefish C. nasus in Lake Ioni in eastern Chukotka has been studied for the first time. According to the results, the linear growth rate in whitefish decreases with age. The maximum body-length increase was recorded in the first year of life. The linear and weight growth data for the whitefish populations from Lake Ioni and the middle Anadyr River have been subjected to a comparative analysis.

楚科奇东部北极艾奥尼湖白鲑（Coregonidae）的大小-年龄结构及其生长

摘要

在楚科奇东部的艾奥尼湖中，首次研究了沙丁鱼Cisco Coregonus sardinella，西伯利亚白鱼C. lavaretus pidschian和阔白鱼C. nasus的大小-年龄结构和生长。根据结果​​，白鱼的线性增长率随着年龄的增长而降低。最大的体长增加记录在生命的第一年。对来自爱奥尼湖和中阿纳德尔河中白鱼种群的线性和权重增长数据进行了比较分析。
