Abstract

The information currently available in the literature as regards gametogenesis in the pink salmon Oncorhynchus gorbuscha Walbaum is summarized. The periods of indifferent development and sex differentiation, the features of testis and ovary development, and the formation of fecundity are considered. The patterns of sex reversal, which is unique for salmonids, and also the evolutionarily acquired specific features of oogenesis for providing the short life cycle are analyzed.

摘要 总结了有关粉红鲑(Oncorhynchus gorbuscha Walbaum)配子发生的现有文献资料。研究考虑了无性发育期和性别分化期、睾丸和卵巢发育的特征以及繁殖力的形成。分析了鲑科鱼类特有的性别逆转模式,以及进化过程中获得的卵子发生的特殊特征,以提供较短的生命周期。

期刊介绍: The Russian Journal of Marine Biology was founded in 1975 by Alexey V. Zhirmunsky, member of the Russian Academy of Sciences. The Russian Journal of Marine Biology covers a wide range of research and some applied aspects of marine biology as a synthetic science related to various fields of study on marine biota and environment. It presents fundamental research on biological processes at molecular, cellular, organismal, and populational levels in marine organisms. Consideration is given to marine objects as models in life sciences. The journal also publishes papers dedicated to events in Russian and international marine biological science and the history of biology.
