Abstract
Untreated fish waste has the potential to cause environmental pollution, while catfish aquaculture faces the challenge of high commercial feed costs. This study aims to analyze the potential of Black Soldier Fly (BSF) larvae in the bioconversion of discarded fish waste and the improvement of substrate nutritional quality as an alternative feed ingredient for catfish. The experiment was conducted using four variations of media composition consisting of rice bran and discarded fish waste, followed by the formulation of three types of feed based on BSF larvae meal, which were tested on catfish for 10 days, along with a gate-to-gate carbon footprint analysis. The results showed that an increasing proportion of fish waste improved the protein and lipid content of the larvae, with the best treatment (V4) yielding 11.31% crude protein and 9.87% crude lipid. The feed formulation with the highest proportion of BSF larvae meal (V3) produced 17.93% crude protein and 14.43% crude lipid, approaching the Indonesian National Standard (SNI) requirements, and resulted in 22.7% weight gain and 100% Survival Rate of catfish. The carbon footprint was dominated by LPG consumption during the drying process (97–98%), with emission intensities ranging from 1.2888 to 1.6018 kg CO2e per kg of feed. This study concludes that BSF larvae are effective in converting discarded fish waste into high-nutrient biomass with potential as an alternative feed for catfish; however, optimization of energy efficiency in the drying process is necessary to reduce the carbon footprint and support sustainable production systems.
