Abstract
The purpose of this study was to determine whether maggot meal and earthworm meal have the potential to replace fish meal as a protein source in artificial feed formulations including assessing their effect on specific growth rate (SGR), rate of relative growth (RRG), ratio of feed conversion (RFC), feed efficiency (FE), and survival rate (SR) nirwana tilapia (Oreochromis niloticus). This study used an experimental method with a completely randomized design (CRD), 4 treatments (F1, F2, F3, and F4) and commercial feed (CF) as a comparison. Nirwana tilapia were the experimental fish, with an average weight of 30.14 ± 0.02 g. The treatment applied was the use of maggot meal for fish meal substitution of 5% to 20% and 4% earthworm meal. The treatments are F1 = 30% fish meal (FM) + 5% maggot meal (MM) + 4% earthworm meal (EM), F2 = 25% fish meal (FM) + 10% maggot meal (TM) + 4% earthworm meal (EM), F3 = 20% fish meal (FM + 15% maggot meal (MM) + 4% earthworm meal (EM), and F4 = 15% fish meal (FM) + 20% maggot meal (MM) + 4% earthworm meal (EM). Relative growth rate (RRG), specific growth rate (SGR), survival rate (SR), feed conversion ratio (RFC), and feed efficiency are the variables identified in this study (FE). The SGR, RRG, FE, and SR values of nirwana tilapia can increase while the RFC value decreases with the addition of animal protein sourced feed containing maggot meal and earthworms. In fact, the use of maggot meal and earthworm meal at F3 (20% FM + 15% MM + 4% EM) with 25.32 protein produced RRG (2.81%) and SGR (1.65%), RFC (2.89%), FE (34.58) and SR (95%) which was almost the same as the use of commercial feed (CF) with 26% protein which produced RRG (2.87%) and SGR (1.67%), RFC (2.86%), FE (34.74) and SR (95%). Water quality in nirwana tilapia culture media (temperature, dissolved oxygen (DO), pH (power of hydrogen), ammonia) was also concluded to be within the appropriate range for nirwana tilapia cultivation.
