Fish stomach analysis is a study of the relationship between the composition of natural feed in the stomach and its habitat, such as plankton, benthos and others. Snakehead fish (Channa striata) and baung fish (Mystus murus) are one of the fisheries resources that have important economic potential in South Sumatra Province. Stomach content analysis research can provide basic information to preserve the population of snakehead fish and baung fish. The purpose of this study was to determine the composition of the food in the stomach contents of snakehead fish and baung fish which includes main food, complementary food and additional food. This research was conducted in February 2019 at the Fish Biology Lab, Public Water Fisheries Research Institute and Palembang Fisheries Extension.

The results obtained in snakehead fish that the main food (IP 46.61%) is leftover food, complementary food (IP 26.21%) is fish pieces and there are 2 types of additional food (IP 19.42%) in animal debris. (Unidentificated) and (IP 7.76%) in insects. Then the results on baung fish that the main food (IP 61.63%) is fish pieces, complementary food with (IP 21.8%) is leftover food and there are 2 types of additional food (IP 13.09%) in animal debris (Unidentificated) and (IP 3.48%) remaining shrimp.
