Abstract
The animal industry especially aquaculture and poultry sectors contribute greatly to the livelihoods of
households in sub-Saharan African countries. The ongoing depletion of fish stocks used as protein source
requires substitution with alternative animal sources, e.g. black soldier fly (BSF) larvae, Hermetia illucens.
Hence, this study assessed the growth performance of BSF larvae reared on locally and readily available organic
wastes. Five organic waste types/substrates (cattle and swine dropping, chicken house rearing waste,
decomposing avocado and millet brew wastes) were tested. Randomly selected third larval instar of BSF from
each rearing substrate were measured: girth (in cm), length (in cm) and weight (in grams) using a vernier
calliper and a weighing scale respectively. The findings indicate that in the 12 weeks period, millet brew wastes
produced larvae with the widest girth, longest length and were heaviest, followed by decomposing avocado,
waste from chicken rearing house, cattle and swine droppings. In conclusion, the growth performance of BSF
larvae was influenced by substrates investigated. We recommend further studies to determine the nutritional
composition of BSF larvae raised on each of the substrates investigated in this study.
