Replacement of Commercial Feed with Fresh Black Soldier Fly (Hermetia illucens) Larvae in Pacific White Shrimp (Litopenaeus vannamei)

This study evaluated survival, growth performance, digestive enzyme activities, intestinal histology, and antioxidant activities of the Pacific white shrimp (Litopenaeus vannamei), which were fed with five different diets, containing 0%, 25%, 50%, 75%, 100% fresh black soldier fly larvae (BSFL), respectively, to replace commercial feed at an equal wet weight. The cultured experiment was lasted for 45 days, results showed that survival rate (SR), final body weight (FBW), gain (WG) negatively related replacement BSFL in diet, where maximum value found 25% group, while minimum appeared group. When level or above SR, FBW WG significantly decreased. However, hepatosomatic index (HSI) increased increasing level, higher 75% groups than other groups. No significant differences on hepatopancreatic amylase lipase observed among all compared control protease activity when up replaced. histological structure intestine gradually changed pathologically, such as tissue disruption, proportion diets. A reduction fold height a decreased thickness muscular also treatment serum SOD GSH-PX In conclusion, replacing 50% could be feasible L. vannamei farming performances, enzymes being considered.
