Food habits of endemic opudi fish (Telmatherina prognatha, Kottelat 1991) in Matano Lake, South Sulawesi, Indonesia. Biodiversitas 21: 1373-1378. The opudi fish (Telmatherina prognatha) is endemic fish in Matano Lake, South Sulawesi. This study aims to analyze food habits of the opudi fish.

Analysis of the diet includes index stomach content (ISC), occurrent frequency and index of preponderance (IP). The fish was consisted of 687 males and 478 females. Stomach contents of the fish consisted of three kinds of foods such part of insect, debris and plankton. IP for male consisted of part of insect (58%), debris (13%), and plankton (Nitzschia sp.
