Prey Composition of Spotted Scat,

\nFood habits and feeding ecology research are a fundamental tool to understand fish roles within their ecosystems. Fish sampling was conducted from May to July 2024 in Madong – Sei Nyirih waters. 85 fish samples were analysed by prey item, occurrence frequency, and volume of prey. The spotted scat showed flexibility in their feeding ecology was based on prey composition. The gut contents showed an ontogenetic shift in diet with an increase in length, the main food of the smaller specimens (<100 mm SL) consisted of different species of algae, while larger sized (>100 mm SL) fish have the most diversified prey items in their diet, although algae were predominant.\n
