Navaga, Eleginus nawaga, are an important component of some Arctic shelf seas, primarily in the Russian Arctic, yet very few publications on Navaga are available in the western scientific literature. Based on literary sources, a description of the distribution and biology of Navaga, Eleginus nawaga, in the White Sea, as well as a history of their fishery, are provided. Long-term changes in biological parameters of several Navaga populations, as well as the current state of the Navaga stocks are summarized. In recent decades, the size and age structure of Navaga populations have undergone significant changes. In Onega and Dvina bays there was a significant rejuvenation of stocks; in contrast, an aging population was observed in Mezen Bay and the Voronka, which was due to climatic changes in all areas of the White Sea. Catches of Navaga have remained at a stable level for more than 100 years, which indicates a stable state of the stocks of this species. Future studies of Navaga in the White Sea should focus on such important aspects as migration, spatial and vertical distribution of juveniles and adults, population structure, biomass and population dynamics, fishing and natural mortality, as well as habitat conditions.

Navaga Eleginus nawaga of the White Sea：以苏俄文学为重点的简要回顾

Navaga，Eleginus nawaga，是一些北极大陆架海的重要组成部分，主要位于俄罗斯北极地区，但西方科学文献中很少有关于 Navaga 的出版物。根据文献资料，提供了对 Navaga、Eleginus nawaga 在白海的分布和生物学的描述，以及它们的渔业历史。总结了几个纳瓦加种群生物参数的长期变化，以及纳瓦加种群的现状。近几十年来，纳瓦加族群的规模和年龄结构发生了显着变化。在 Onega 和 Dvina 湾，股票显着恢复活力；相比之下，由于白海所有地区的气候变化，在梅岑湾和沃龙卡观察到人口老龄化。100 多年来，Navaga 的渔获量一直保持稳定水平，这表明该物种的种群处于稳定状态。未来对白海 Navaga 的研究应侧重于迁移、幼鱼和成鱼的空间和垂直分布、种群结构、生物量和种群动态、捕捞和自然死亡率以及栖息地条件等重要方面。
