Technical basis for the small-scale production of black soldier fly, Hermetia illucens (L. 1758), meal as fish feed in Benin

Promoting black soldier fly (BSF) rearing in Benin to replace fishmeal fish diet could reduce production costs. This study aims set up a breeding technique of BSF as protein source. reproduction has been carried out sunlight. Two densities (8500 individuals/m3 and 10,500 individuals/m3) associated with 2 attractants (soybean pineapple waste) were tested on imago egg-laying. A larvarium prepupae self-harvesting system was designed its efficiency evaluated by testing 3 larval (1 larva/g, larva/g). diets, VGD meal ?+ ?euphorbia leaves seeds ?colza oil) FOD ?fish offal) formulated optimize polyunsaturated fatty acid profile meet nutritional requirements tilapia. Best oviposition obtained 8500 waste optimal load density larva/g. Prepupae fed accumulated C18:2n-6 (10.1%) which is essential for contained C20:5n-3 (2.20%), beneficial humans. The lowest cost estimated at $1.84/Kg the diet. can easily be reared under local conditions throughout year. Its qualities are very interesting Nile tilapia requirements.
