    Abstract:

    A basal diet without adding maggot meal(MGM) and six test diets containing 1.0%, 1.8%, 2.6%, 3.4%, 4.2%, 5.0% of the MGM were prepared to feed seven groups of black carp(Mylopharyngodon piceus) in triplicate with an initial average body weight of (127.42±4.83) g respectively for eight weeks. The results showed the Black carp fed the diet containing 5.0% MGM had higher final body weight(FBW), body weight gain(BWG), specific growth rate(SGR) and lower feed conversion ratio(FCR) than the others. The HIS and VSI decreased significantly when adding 5.0% MGM compared with control group (P<0.05). Body composition analysis showed that whole crude protein content increased significantly with the increasing of MGM levels(P<0.05). Compared with the control group, the crude protein content of fishes muscle increased significantly when adding 3.4%, 4.2%, 5.0% MGM(P<0.05). Intestine and hepatopancreas protease, intestine amylase activities of fish fed diet with 4.2% MGM were higher than those of fish fed the basal diet (P<0.05), hepatopancreas and intestine lipase activity increased with the increasing level of MGM supplement up to 5.0%. In conclusion, under the condition of this experiment, adding 4.2%-5.0% MGM to black carp diet could improve fish growth, digestive enzymes activities, whole fish crude protein content and muscle quality.
