Преднерестовое и после нерестовое состояние яичников густеры Blicca bjoerkna (Linnaeus, 1758) в условиях нижнего Прута [Articol]

Abstract

Pre-spawning and post-spawning condition of the ovaries of the white bream Blicca bjoerkna (Linnaeus, 1758) in the Lower Prut. The white bream (Blicca bjoerkna) from the lower Prut River can be classified as a fish species with a conditionally short life cycle, characterized by a small number of age groups. It has been established that the length-weight parameters in female white bream from the lower Prut are slightly higher than those of individuals from the lower Dniester. Sexual maturity in females occurs at the age of two years. Oogenesis is characterized by asynchronous development of germ cells and fractional spawning. The spawning season begins in the first decade of May, at a water temperature of 16°C.
