Study of Different Protein Content of Feeding of Local Raw Materials on Gourami Fish ( Osphronemus goramy Lac.) Aquaculture Performance

Gourami (Osphronemus goramy Lac.) is one of the freshwater fish commodities that has high economic value because of its delicious meat taste which is very popular with all people. However, the feed commonly used by carp cultivators is factory-made feed, namely commercial feed which usually costs quite a bit because some of the ingredients for commercial feed are imported from abroad. Therefore, it is necessary to find a solution to reduce the cost of aquaculture production by replacing commercial feed with homemade feed made from local raw materials. The purpose of this study was to examine the use of local raw materials formulated to make feed suitable for the growth of gourami and to analyze the cost of producing carp feed made from local raw materials. This study consisted of 4 treatments and 3 replications using a completely randomized design (CRD). The treatments consisted of treatment A (Protein 30%), B (Protein 33%), C (Protein 36%), and D (Commercial). The results of this study showed that the treatment of feed A, B, and C produced the same growth as commercial feed, and treatment of feed A resulted in the lowest cost of feed production compared to other treatments.
