Growth Performance of Mutiara Catfish (Clarias gariepinnus) Fed a Combination of Commercial Feed and Black Soldier Fly Maggot (Hemetia illucens)

The purpose of this research was to determine the appropriate combination of commercial feed and maggot to produce optimum growth, feed efficiency and food conversion ratio for catfish. This research used experimental method with Completely Randomized Design (CRD) consisting of four treatments and four replications. The study was conducted in the Ciparanje Land Fisheries Area, Faculty of Fisheries and Marine Sciences, Padjadjaran University. The research was carried out between January - July 2019. The treatments are combination of commercial feed and maggots consisting of A (control, 100% commercial feed), B (75% commercial feed + 25% maggot), C (50% commercial feed + 50% maggot) and D (25% commercial feed + 75% maggot). The parameters observed were survival rate, daily growth rate, length ratio, feed efficiency, food conversion ratio and water quality. The combination of commercial feed and maggots affected the daily growth rate, length ratio, feed efficiency and food conversion ratio of catfish. The survival rate of each treatment was 88.75, 92.50%. Treatment C showed the value of highest daily growth rate, length ratio, feed efficiency namely 1.86%, 1.40%, 65.09% respectively and the lowest feed conversion ratio 1.54%.
