Using a mixture of natural forage in growing of yearlings of carp under conditions of recirculation installations

The basic fish-breeding and biotechnological and biological indicators of yearlings of scaly carp grown in recirculation installations using forage mixture of natural food objects were researched. It was established that the introduction of natural fodder for feeding carp in controlled conditions positively affect the growth of fish. Using histological studies it was determined that in terms of growing fish in closed water plants, feeding fish with natural feed ingredients have positive effect on the metabolism in the body of the fish.
