【 摘 要 】

Increase of production of fish by traditional methods, based primarily on the extensive use of natural resources, has certain natural limitations.The limiting factors are land, water and the environment. Considering this fact, the perspective expansion of industrial farms, provided with superintensive technologies, is actual. The role of abiotic environmental factors in the life of fish is enormous. For example, the water temperature determines the intensity of metabolism and is a natural stimulus determining the begining of spawning migration of fish. Water temperature has a very important influence on the life of the organism, particularly on the metabolic processes, the behavior and dispersion of organisms. Water quality is one of the most important factors stimulating the development of water biotechnology. In this regard, we explored the physical and-chemical features of the Volga water from the viewpoint of the trout-breeding. The analysis revealed that the water does not fully meet the required water quality for trout ponds. Characteristics as pH, absence of hydrogen sulfide meet the requirements; such indicators as permanganate and bichromate oxidation, BPK5, ammonium ion, nitrates and nitrites, oxygen content are noted exceeding the standard values for trout farms. Power engineering and fish farming are connected closely - power plants contribute to the creation of favorable conditions for the cultivation of commercial fish, including valuable and fish-breeding complexes based on water coolers help to improve their environmental condition. At the same time in Russia in recent years, this industry is beginning to receive attention it deserves. The experience of Western countries shows a new direction of the industry development: in the previous period the favorable conditions for growing and breeding fish were created on the basis of the warm water for increasing production capacity of energy enterprises due to energy production and fish production, nowadays the power plants are built at fish-breeding enterprises in order to optimize costs and increase profitability of fish production.
