The effect of banana peel flour (Musa paradisiaca) as additional feed raw materials for common carp (Cyprinus carpio)

Abstract

Banana peel flour has a high nutritional content and can be used as a raw material for fish feed. The study was to find out the effect of banana peel flour as a raw material for feed on enhancing common carp fish growth. The study was conducted from February to April 2023 at the Fish Hatchery and Breeding Laboratory, Faculty of Marine and Fisheries, Universitas Syiah Kuala. The experimental group used a CRD with 5 treatments and 3 replications. The treatments included T0 (0%), T1 (2.5%), T2 (5%), T3 (7.5%), and T4 (10%) doses of additional Kepok banana peel flour. The sample fish used were an average weight of 1.64 ± 0.24 g fish.-1, which was cultured for 40 days. The parameters observed included survival, growth rate, and feed conversion ratio. The results revealed that adding Kepok banana peel flour as a raw material for common carp feed had a significant influence on absolute weight growth, specific growth rate, and feed conversion ratio (P<0.05), but had no effect on survival (P>0,5). The optimal percentage obtained was the addition of 7.5% banana peel flour in the feed formulation (T3) which was able to produce 1.73 ± 0.12% day-1 SGR. Hence, the addition of Kepok banana peel flour as a feed raw material is quite effective in supporting the growth of common carp.
