REARING EFFICIENCY AND NUTRITIONAL QUALITY ASSESSMENT FOR CARP SAPLING (CYPRINUS CARPIO LINNE, 1758) FROM RECIRCULATING SYSTEMS

Abstract

Common carp, Cyprinus carpio L. of 8 months older, rearing in recirculation system during 107 days period - he has been analysed from the point of view of feeding efficiency and nutritional quality of carp carcass. The stocking of breeding ponds has been made at 12.17 kg/m3 density, the initial average weight of fishes has been 82.2 g/ex., biochemical composition of carp carcass has been following: protein 14.35%, fat 1.10%, ash 1.67% and moisture 82.22%. Weekly, there has been analysed biochemical composition of meat and protein efficiency coefficient (PER), protein using efficiency (PUE), retained protein (RP). The nutritional quality of fish meat and appreciation coefficients of fish rearing they indicate a good capitalization of delivered food.
