- Abstract
The experiment was to study the feasibility of using yellow mealworm dung as bait for shrimp. Using mealworm dung, mealworm larva meal, whole wheat meal and shell meal as feed materials, the changes of crude protein, crude fat and amino acids before and after fermentation of mixed feed were studied, and the effect of three diets on growth performance of crayfish were investigated with unfermented mealworm dung feed and commercial high calcium shrimp feed as control. The results showed that the content of crude protein, crude fat, small molecular peptides, organic acids, free amino acids and soluble calcium in fermented faecal bait were higher than those in unfermented faecal bait. The feed efficiency and shell calcium content of crayfish in fermented fecal diet group were higher than those in unfermented fecal diet and commercial diet. Fermented faecal bait was more attractive. The experiment indicates that it is feasible to make mealworm dung into shrimp feed, which can provide reference for resource utilization of mealworm dung.
