The elements of circular technologies in aquaculture on various energy waters are considered. The development of forms of aquaculture from pasture to industrial with an increase in the share of circular technologies is shown. It is noted that the use of cage fish farming on warm waste waters of energy facilities is complicated by eutrophication at high fish stocking densities and the peculiarities of temperature and hydrochemical regimes. The necessity of selection of new aquaculture objects with a fast growth rate, thermophilic and not demanding to the oxygen content in water is noted: a promising object of cultivation in warm waters is the African clary catfish (Clarias gariepinus). Possibilities of including other representatives of catfish - shill catfish (Pangasius) are considered. The results of experimental cultivation of spicy vegetable crops on waste products of crucian carp and clary catfish are presented. The analysis of own data and data of foreign sources is carried out. The dependence of the growth of valuable plant species on the type of fish in aquaponics is shown. Aquaculture and aquaponics as specific components of the modern agricultural sector in the development are focused on industrial production technologies using circular technologies for the efficient use of resources.
