The purpose s of this research were to determine the effect of fish meal substitution with
maggot with different compositions on absolute, relative, and daily growth of tilapia fry,
determine the effect of fish meal substitution with different maggot compositions on the
efficiency and FCR of tilapia seeds. This study used a completely randomized design with 5
treatments and 3 replications to obtain 15 experimental units. The results showed that fish meal
substitution had a significant effect on fish growth, feed efficiency and FCR. Feed with the
addition of 40 grams of maggot, namely treatment A, gave good growth results compared to
treatments B, C, D, and E. The proximate test results for each treatment found that feed treatment
A, namely the addition of 40 g maggot, showed better protein content compared to treatments B,
C, D, and E. For absolute growth, the best results were shown in treatment A of 3.49 grams,
relative growth of 112.58%, daily growth of 2.51%, feed efficiency value of 77.79%, and
conversion ratio feed of 1.28.
