Abstract: Feed is an important element in supporting the growth and survival of fish. Availability and quality of feed is a factor that determines the success of cultivation. So far, some fish farmers still rely on feed directly from nature, such as small fish and leaves. The price of commercial feed is currently very expensive, so the costs incurred for feed are felt by fish farmers. To reduce feed prices, looking for alternative protein sources that are cheaper and easier to obtain is necessary. Therefore, it must provide other alternatives such as natural feed whose availability does not depend on the season, for example Maggot or black soldier fly larvae (Hermetia illucens) which are alternative feeds because they meet the requirements as a source of protein. The purpose of this study was to determine the comparative effect of feeding maggot (Hermetia illucens) and commercial feed on the growth rate of common carp (Cyprinus carpio) seeds, as well as to find out the best feeding on the growth rate and survival of common carp seeds. This study used a Complete Randomized Design (CRD) with 5 treatments and 4 replications. The frequency of feeding is 2 times a day at 08.00 and 16.00 morning and evening as much as 5% of fish biomass. Weight, length, survival rate and water quality measurements were carried out every 7 days. The results of the study showed that the highest growth in length and weight was found in the P3 treatment with a combination of 25% commercial feed and 75% maggot, namely 9.33 cm and 10.23 grams, and a survival value of 90% -100%.
