Proximate composition of initial (5-days old) and final (12-days old) black soldier fly larvae reared on six different substrates (chicken feed (CF), mixed feed (MF), brewer’s spent grain (BG), mitigation mussels (MM), rapeseed cake (RC), and shrimp waste (SW)).

All values are shown as mean ± standard error (SE; n = 3) for percentage of wet weight (%WW), percentage of dry matter (%DM), or kJ/g dry matter (DM). Corrected crude protein is calculated using the nitrogen-to-protein conversion factors described in Table 4. Dissimilar lower case superscript letters represent significant differences between means within the same column (p < 0.05).
