Abstract

A comparative slaughtering analysis has been carried out at the Institute of Fisheries and Aquaculture, Bulgaria upon two-summer old silver carp, reared in polyculture (H. molitrix 300 p-ces.ha-1 and C. carpio – 2000 p-ces.ha-1) under the conditions of integrated with ducks (Peking ducks and mule ducks) and non-integrated technologies. The fish in all experimental ponds have grown well and no considerable difference has been observed between the separate variants as regards the final live weight. The integration has exercised a positive (F=4.182; P<0.005) effect upon the slaughtering output, however, this effect has not been preserved as regards the relative fillet share within the fish carcass (F=0.096; P<0.05).
