摘要：Banana peels contain the amino acid tryptophan which is thought to support growth and suppress cannibalism in giant prawns. The purpose of this study was to evaluate the efficacy dietary supplementation of banana peel meal on growth performance and cannibalism level of giant freshwater prawn (Macrobanchium rosenbergii). Four isonitrogenous and isocaloric experimental diets were prepared by supplementing different levels of dietary banana peel meal: a control group, four groups supplemented with banana peel meal (0, 2.5; 5 and 7.5% of weight feed) were fed to triplicate groups with the density of 200 giant prawn m−3. After a 45-day feeding experiment, the growth performance includes weight gain, daily growth rate, feed efficiency, and cannibalism level were measured. Banana peel meal supplementation significantly decreased (P <0.05) cannibalism level at 5% weight feed. In addition, its weight gain and feed efficiency significantly higher but the daily growth rate was not significantly different. The result of the present study suggested that feed efficiency increased and the cannibalism level of giant prawn significantly decreased by feeding diets supplemented with banana peel meal (5% of weight feed).
