摘要：The article presents the results of experiments on the use of the aquaponics method. Aquatic animals release products toxic to them themselves: nitrogenous, phosphorus, potassium compounds, carbon dioxide. The accumulation of these substances in water is the main problem as in closed industrial aquaculture. The same substances are absolutely necessary in hydroponics and they are added to water to obtain nutrient solutions for plants. Given that environmentally friendly products are increasingly popular and demand for them is constantly growing, there are prospects for introducing this innovation in the southern regions of Russia. Due to an increase in parsley yields in the aquaponic plant by 7.3%, an additional profit was received 4.8 rubles from 1 square meters.
