Abstract
The high protein content and complete nutrition are the main reasons for maggots as a source of animal protein for fish feed. This research aims to substitute fish meal (FM) in feed with maggots meal (MM) in snake head fish formulation feed. The study used a completely randomized design with 4 treatments and 3 replications A(100%FM), BFM75%; MM25%), C (FM50%;MM50%), D(25FM;75%MM). Feeding was carried out 4 times a day for 60 days with a density of 1 fish/l. The results of the ANOVA statistical test on survival and relative weight showed that there were no significant differences between all treatments. The survival value of treatments A, B, C and D was >90%, the highest relative weight gain was on the 30th day of treatment C (23.52 ± 2.37), on the 60th day the relative weight value for all treatments was between 39, 86±4.68 to 42.76±3.90. Treatment C showed the best feed responsibility and feed storage for up to ± 2.5 months. Fat analysis will be higher by increasing the percentage of maggot meal in the feed. It was concluded that the use of fish meal substitution with maggot meal up to 75% in feed can still be used for rearing snakehead fish
