One of the most promising materials with great potential as a nutrition source of animal feed is the black soldier fly prepupae (BSFP) (Hemetia illucens) which is fed with organic wastes. This study was designed to observe the accumulation of omega-3 from the organic wastes of marine fish offal and tofu dregs converted as the biomass of the harvested BSFP. A total of 150 g food consisted of marine fish offal and tofu dreg with different proportions of fish offa1:tofu dreg at 10:90, 25:75, 50:50, and 100% tofu dregs were fed to black soldier fly larvae (BSFL) for 21 days. At the end of the feeding period, all BSFL were harvested, weighed, and then analyzed for omega-3 fatty acids content using Gas Cromatography with Flame Ionization Detector (GC-FID). Results showed that BSFL reared with 25% marine fish offal produced the highest biomass (8.1 g/50 larvae) with the least development time (19 days). The total omega-3 recorded from the application of OO/o, 10°/o, 25%, and 50% of marine fish offal was 0.02%, 0.87%, 2.16% and 2.61% in 100 g of dry weight, respectively. These results showed the possibility of producing specific nutrients from BSFP biomass converted from organic wastes, thereby providing baseline knowledge for further formulation of specific animal feed from BSFP. © 2021, Biotropia.
