The result showed that chopped fresh fish (Poecilia reticulata) and commercial dry food were the best food for maturating the fish gonad of bagrid catfish (Mystus nigriceps). Total fish reached matured stage IV was 16 fish (88,89%), gonad somatic index 9,06 %, relative fecundity 835 eggs/g fish, egg diameter 0,85 mm. The temperature range from 28 – 310C, pH 5 – 6, DO 5,7 – 6,8 ppm.Keyword: food types, Gonad maturation, bagrid catfish]]>
