Black soldier flies (Hermetia illucens) have been marvelled at their ability to convert waste into high quality protein and their ability to improve the growth and immune function in fish. However, not much is known about how insects do this. We aim to feed rainbow trout (Oncorhynchus mykiss) different fractions of black soldier flies (protein, fat and fibre) to determine these corresponding effects.
