Features of tench reproduction and larvae transfer to active nutrition

The aim of the study is to investigate the features of reproduction and transfer to active feeding of tench larvae. Objectives: search for scientific literature on the topic of tench reproduction technology and transfer of larvae to active feeding, systematization of data and compilation of a literature review. For the review, published scientific papers on the production and reproduction of tench, the features of its breeding were used. A total of 250 domestic and foreign sources were analyzed. To collect material on the topic of the work, the following databases were used: https://elibrary.ru, https://cyberleninka.ru, www.researchgate.net, etc. Artificial reproduction of tench is especially relevant in the context of a decrease in the population in natural reservoirs and a reduction in production. Tench can be effectively used for breeding as the main and additional object: in peat ponds with an acidic environment; in estuaries and ponds on saline soils; in ponds with high overgrowth; in farms unfavorable for aeromonosis. One of the most important steps in solving the problems of tench reproduction is the development of methods for stimulating the maturation of gonads to obtain reproductive products at an earlier date, as well as the development of recipes for artifi-cial feeds that, when used, promote an increase in growth rates and survival rates, as well as provide envi-ronmentally friendly products. Due to the high demand for tench fish seed and the growing interest in the aquaculture of this species, it is necessary to create new highly effective methods for artificial tench bree-ding and growing juveniles in industrial farms. These methods should be applicable in various conditions and used for both reproduction and intensive breeding.
