Tench (Tinca tinca Linnaeus, 1758) as an object of non-traditional aquaculture (a review)

Purpose. Tench (Tinca tinca)is a popular species of cyprinids that lives in our waters. It has small scales that are firmly embedded in the mucous membrane of the skin. This is one of the few European fish that has sexual dimorphism. Tench is found in almost all regions of Europe, except the northern part of Great Britain, Iceland and the northern part of the Scandinavian countries. Interestingly, this species can be found in waters with low salinity, especially in the Baltic Sea, in its coastal zone. This species easily survives in waters with low oxygen content. As a rule, it prefers standing or, at best, poorly flowing waters. The ideal conditions for tench are shallow waters with warm water and developed vegetation. In deeper lakes, it lives in the coastal zone. Its meat is considered valuable. High economic importance and low production of tench in aquaculture in recent years has led to the development of scientific activities aimed at determining the most optimal possible production parameters of this species. Findings. The author of the work reviewed and analyzed professional scientific literature sources, manuals and textbooks of domestic and foreign authors on the cultivation of tench as an object of non-traditional aquaculture. In particular, the historical aspects of tench cultivation, its biological characteristics and features of breeding are considered. Practical value. The review of literature sources can be useful for the preparation of lecture material during the training process for specialists in specialty 207 “Aquatic Bioresources and Aquaculture”, including specialists in ichthyology, veterinary medicine, zoology.
