Pleco fish (Gliptoperichthys gibbiceps) is an invasive species at Tempe Lake, Sulawesi Selatan, Indonesia. Increasing population affects native fish and local fishery. The pleco fish obtains no economic value, so discouraging local communities to invest in management projects due to lost costs. A potential of using the pleco fish as feedstock for black soldier fly maggot: BSF (Hermetia illucens) was examined. Four treatments (1:1, 1:2, 1:3 and 1:4 w/w of the pleco fish puree: the BSF maggots) were analyzed. The treatment 1:4 obtains the fastest consumption time of average 7.74 hours (SD = 0.20), followed by 1:3, 1:2 and 1:1, respectively. The BSF maggots contain the highest amounts of protein (39.36%), followed by fat (37.00%), and crude fiber (6.86%). The most abundant amino acids are palmitic and palmitoleic acid (24.96% and 21.36%, respectively). These findings determine the potential use of pleco fish for BSF maggot feedstock production. However, further analysis is needed, especially for large scale production. © 2022, Thai Society of Higher Eduation Institutes on Environment. All rights reserved.
