ТHE DYNAMICS OF MICROSTRUCTURAL CHANGES IN THE LIVER AND THE GONADS IN Acipenser ruthenus IN CONDITIONS OF CLOSED WATER SUPPLY
Journal Title: Водні біоресурси та аквакультура - Year 2018, Vol 2, Issue
Abstract
The dynamics of microstructural changes in the liver and gonads of five-year old individuals in Acipenser ruthenus was studied. Synchronous functioning of the digestive system and reproductive organs is shown. The specificity of cytological processes is determined. It has been proved that physiological regeneration of gonads in the development cycle is reflected in the liver morphology. The obtained data can be used for the control of the quality of the sexual products in the conditions of fish farming enterprises.
