The Tench is the perspective subject for agricultural reservoirs

Abstract

The most important link in the solution of the Tench reproduction issue is the receipt of fish seed material at the earliest possible time. There are limited information about Tench reproduction as a traditional (natural spawning), and enterprise (physiological method) methods in the literature. In the Russian Federation there are not selected herds and farms with adapted tench herds.There is also no approved modern technology for breeding this species. The article presents materials about growing various age groups of the Tench. The main morphometric indicators are presented. The necessity of the biotechnology perfection of the growing and improving the breeding methods with Tench producers, the search of the fast-growing forms and the shifting of spawning with the aim of obtaining a more homogenous by the weight progeny are substantiated.
