After decades of work in Tifton, Georgia, University of Georgia researchers think soldier flies will be a viable alternative to fish meal in aquaculture diets. Early work with the black soldier fly (Hermetia illucens) used manure as the growth media, but recent efforts show that food byproducts can be a better soldier fly diet. Catfish grow well on soldier flies and other fish, including tilapia and rainbow trout have been fed the prepupae. The most exciting opportunity shows that changing the composition of the soldier fly diet will change the final composition of the soldier fly prepupae in a valueadded way.
