МОРФОФИЗИОЛОГИЧЕСКАЯ ХАРАКТЕРИСТИКА ГОНАД ПОЛОВОЗРЕЛЫХ САМОК БЫЧКА-ПЕЧСОЧНИКА NEOGOBIUS FLUVIATILIS (PALLAS, 1814) НИЖНЕГО ДНЕСТРА

Abstract

The results of studies of the reproductive system of sexually mature female monkey goby Neogobius fluviatilis (Pallas, 1814) of the lower Dniester during the spawning season are presented. Asynchrony in the development of germ cells was revealed, which ensures four-time spawning throughout the entire breeding season of fish, from April to July. The dependence of the development of oocytes of subsequent generations on the temperature regime of the reservoir was noted. The timing of the release of the next generation of eggs during the breeding season of the sand goby has been identified.
