Abstract

Data are presented on changes in the activity of the membrane-bound osmoregulatory enzyme Na⁺/K⁺-ATPase and lipid composition in the gills of pink salmon Oncorhynchus gorbuscha during spawning migration from the White Sea to the river environment through the estuary. The compensatory reaction of pink salmon in a hypoosmotic environment is accompanied by a decrease in Na⁺/K⁺-ATPase activity and a change in the content of phosphatidylserine and polyunsaturated fatty acids (linoleic, eicosapentaenoic and docosahexaenoic). The results obtained indicate that effective osmoregulation in pink salmon during spawning migration from the sea to the river allows the implementation of a reproductive strategy.

白海粉红鲑（鲑科）产卵洄游过程中鳃的 Na+/K+-ATP 酶活性和脂质成分的变化

摘要介绍了粉红鲑（Oncorhynchus gorbuscha）从白海经河口向河流环境产卵洄游过程中，膜结合渗透调节酶 Na+/K+-ATPase 的活性和鳃中脂质组成的变化数据。粉鲑在低渗透环境中的补偿反应伴随着 Na+/K+-ATP 酶活性的降低以及磷脂酰丝氨酸和多不饱和脂肪酸（亚油酸、二十碳五烯酸和二十二碳六烯酸）含量的变化。研究结果表明，粉鲑在从海洋向河流产卵洄游过程中，有效的渗透调节有助于实施繁殖策略。

期刊介绍： Journal of Ichthyology is an international peer-reviewed journal published in collaboration with the Russian Academy of Sciences. It covers original studies in fish taxonomy, evolution, molecular biology, morphology, species diversity, zoological geography, genetics, physiology, ecology, behavior, reproduction, embryology, invasions, and protection. Some problems of applied ichthyology are also covered. The journal welcomes manuscripts from all countries in the English or Russian language.
