THE EFFICIENCY OF CARP GROWING IN FLOATING CAGES THROUGH RARING AND LOTTING

Cypriniculture is the growth of cyprinids in a controlled environment. By planning and rationalizing feed and creating appropriate conditions to cover the needs of carp farming, this branch of aquaculture is made more efficient. Carp is a poikilothermic animal that does not consume energy to maintain body temperature. Thus, the administered food is converted into body mass more effectively than in other animal species. The feed conversion ratio shall not exceed 2. The action of lotion is differentiated from the one of raring by the process of populating the floating cages according to the weight category in which the carp individuals fall. The study involves the identification of an effective method of growing carps in floating cages, depending on the weight and amount of food administered. The technique of separating carp by lotting was proven to be more efficient compared to decreasing the number of individuals on floating cage. Carp individuals remained in the same weight category without large differences between them. This ensures the uniformity of biological material, and an economic beneficial effect.
