The collection of fish samples was carried out using gill net with 1.5 inchi which is commonly used by fishermen. Sampling was carried out by spreading the net three times. The tested fish samples consisted of 46 individuals with 12 species, 9 families, and 6 orders. The highest number of fish caught was Clupeiformes with a percentage of 41.67%, while the order found with a low percentage was Beloniformes (2%). The families found in large numbers were Mugillidae, the families found in low numbers were Lutjanidae and Serranidae. The species caught the most is Chelon subviridis. Stomach contents analysis was performed with the Index of Preponderance (IP). Based on the type of food found in the stomach contents of the test fish, there were various types of food consisting of 11 types, namely phytoplankton, zooplankton, squid, fish (juvenile fish), crabs, shrimp, shellfish, litter, moss, pieces of insect bodies, and plant parts. The types of food that the plant fragments are found in are 9 fish species, phytoplankton (7 species), shrimp (7 species), and litter (5 species).
