The use of black soldier fly (Hermetia illucens) maggot as an alternative food for catfish (Clarias gariepinus)

Black soldier fly (BSF) larvae (Hermetia illucens) serve as an alternative source of protein substitute for fish meal, which has become limited. In dried BSF larvae, they contain 40 -45% protein, 30 -35% fat, 11 -15% ash, 4.8 -5.1% calcium, and 0.6% phosphorus, and various amino acids and mineral. Larval cultivation as fish feed provides many benefits. The purpose of this study was to determine the effectiveness of the substitution of BSF larvae as an alternative feed that can be used as a conventional feed mixture. The research method used is an experimental method. The study design uses a completely randomized design (CRD). The results of this study found that the best feed conversion ratio using BSF larvae flour for catfish seeds 6-8 and 8-12 cm was found in P2 treatment with a percentage of 50% BSF with 1.26 and 1.24 and the value of the best efficiency of feed utilization in the treatment P2 percentage 50% BSF with a value of 94.9 and 83.43%. Replacement of conventional catfish feed partially or as a whole using BSF larvae can increase the growth in length, weight, and will not affect the survival rate of catfish for breeders and catfish breeders. Catfish feed with a mixture of larvae flour BSF can be used to support the success of catfish cultivation.
