The economic success of the aquaponics industry and fish farming is mostly dependent on the use of inexpensive, nutritionally adequate meals. Approximately sixty percent of the economic balance is accounted for by fish feeding. The substitution of insect meal for fish meal appears to offer a promising approach to reducing cost and the environmental impact. The black soldier fly larvae (Hermetia illucens) possess 40–45% proteins and a favorable essential amino acid profile. The objective of this experiment was to investigate the effects of commercial and black soldier fly larvae (BSFL)-based diet on Nile tilapia growth, plant growth, and antioxidant accumulation in crops. The results showed that tilapia fish can grow at a higher rate on BSFL-based meals than on commercial diets. On the other hand, a study revealed that BSFL BSFL-based fish feed waste water significantly stimulated plant growth and antioxidant accumulation in aquaponic systems. This study opens up new possibilities for using BSFL as a substitute for fish meal, which could help to reduce the environmental effect of aquaponic production systems while also contributing to a circular economy.
