Enhancing aquaculture sustainability and profitability: Effects of black soldier fly larval meal on the performance of African Catfish (Clarias gariepinus) in Cameroon
Description
The integration of sustainable sources of protein is imperative for economically profitable and ecologically friendly aquaculture. In this study, we investigated the potential of insect-based protein in the diet of African catfish as an alternative to fishmeal. The insect-based protein was obtained from black soldier fly larvae meals (BSFLM) obtained using different larvae killing methods was incorporated into the local catfish diet at 0%, BSFLM0; 50%, BSFLM50; 75%, BSFLM75; and 100%, BSFLM100. A standard commercial diet was used as a control and the catfish were fed for an experimental period of 120 days. Each diet was repeated three times and their nutritional value was assessed using growth parameters, sustainability of the system and fish flesh quality. No adverse effect was recorded on fish flesh quality. We concluded that fishmeal could be replaced with BSFLM up to 75% without adverse effect on growth performance, survival, and taste of catfish but reduce the cost of production and increase fish farming sustainability.
