Growing juvenile beluga and its hybrids with sterlet in environmentally friendly conditions

Currently, the general trend of the global fishing industry is to increase the production of fish food products not only due to the development of aquaculture, but also the biological characteristics of the body of sturgeon. The aim of the study was the theoretical justification and practical implementation of the assessment of the growth and development of beluga juveniles and their hybrids with sterlet aged 0+ to 2+ (three-year-olds) in industrial of the Krasnodar Territory. The determined: fish mass, live weight gain, linear growth. By the end of the control cultivation, the weight of fish in the control and experimental groups was 1728.3 and 2236.4 g, respectively. In the experimental group, the absolute increase in live weight of fish was 2198.2 g, while in the control group it was 1692.2 g. The difference in average daily gains was 0.71 g in favour of hybrids. The body length of the fish in the control and experimental groups was 32.7 and 37.3 cm. The positive effect of heterosis had a positive effect on the first- generation crossbreeds obtained from beluga and sterlet

Environmentally oriented control systems

Environmental safety is currently gaining popularity in all areas of human activity. The release of various inorganic and organic chemicals in various industries, textile, pharmaceutical, agricultural and tanneries, is highly toxic to the environment and human health. In order to manage these impacts, it is necessary to prioritize environmental aspects in order to focus on those that will be recognized as more significant and have a greater impact on the environment. The main factors of an environmentally friendly product are production from natural raw materials, in environmentally friendly areas, away from industrial centers. The greening of agricultural activities and the transition of producers to the production of an environmentally friendly product, organic products is relevant, since it is the safety of food raw materials and food products that is one of the main factors determining people's health
