Maturation Performance of Snakehead Fish <i>(Channa Striata)</i> with The Percentage of Feed for Rice Field Snails <i>(Pila Ampullacea)</i> with The Addition of Vitamin E

Abstract Snakehead fish (Channa striata) is a native fish that lives in Indonesia’s public waters which is increasingly economically valuable. Cultivating this fish is a challenge in the gonad maturation process which takes a long time to spawn. Gonadal maturity can be achieved by hormonal manipulation, the environment, and the provision of quality natural feed. One of the feeds that can be used is rice field snails (Pila ampullacea) which are rich in protein, as well as the addition of vitamin E. This study analyzed the effects of natural feed and vitamin E on the reproductive performance of snakehead fish, by giving a feed percentage of 3%, 5% and 7% and satiation. Using a Complete Random Design with 4 treatments and 3 replicates. The results showed that feeding rice snails and vitamin E improved the reproductive performance of snakehead fish with an average of GMR III-IV, gonadosomatic index of 1.34 – 2.60%, hepatosomatic index of 0.84 – 0.95%.
