Proximate Composition of Larvae, Prepupae and Adult in Black Soldier Fly (Hermetia illucens)

The black soldier fly (Hermetia illucens L.) is an insect species and able to convert low-value substrates is highly nutrient feed. Most of the aquaculture industry uses fish meal as a protein source in the diet of fish however fish meal was high in demand, price, and limited hence as an alternative the supplement protein should possess certain content to meet the role of fish meal in aquafeed products. Besides, a lack of research and studies on using BSF as a substitute in fish feed was noticed. This project aims to analyze the proximate composition in larvae, prepupae and adults were freeze-dried at -20°C, ground, and analyzed for proximate composition such as crude protein, crude lipid, ash, crude fiber, and moisture. Data were analyzed using one-way ANOVA to identify the significant difference in proximate composition in the three stages of BSF which are larvae, prepupae, and adult. As a result, the proximate composition revealed that BSF larvae possessed 32.3% crude protein, 26.7% crude lipid, 9.0% ash, 10.1% crude fiber, and 6.9% moisture while BSF prepupae contain 27.0% crude protein, 4.2% crude lipid, 10.6% ash, 8.6% crude fiber and 37.4% moisture also BSF adult have 52.6% crude protein, 15.6% crude lipid, 7.5% ash, 13.2% crude fiber and 25.6% moisture. BSF adult shows the highest crude protein content thus data was able to contribute more information on the nutritional value that potentially can be replaced in the diet of fish feed.
