标题：Investigation of the processes of pollution and reduction of aquatic environment pollution on the example of artificial fish breeding enterprise activities
摘要：An important problem of modem society is the provision of the population with ecologically clean food products in quantity, range and quality, which guarantees an increase in their living standards and preservation of health. The solution to this problem is possible with the effective functioning of food market, dynamic development of agro-industrial complex, including production of marketable fish. Significant reserves for increasing fish production are water bodies existing in rural areas and new ponds being built on lands unsuitable for growing agricultural crops. As practice shows, when using inconvenient land for animal husbandry, we can get the following increase in cattle meat (kg/ha): in low-lying wetlands – 42, steppe, semi-steppe, desert pastures – 20. At the same time, from 1 hectare of pond mirrors built on such lands, an average of 200-300 kg of fish is obtained due to natural fish productivity, and with the use of fertilizers, various methods of reclamation and feeding fish up to 1000-1500 kg/ha. However, on the way to increasing fish productivity is the problem of ensuring water quality of the water body. Thus, the study of the causes and sequence of stages of pollution of water bodies determined the relevance of the research topic [1-3].
