【 摘 要 】

Catfish (Clarias sp.) is a freshwater fish that is widely cultivated throughout Indonesia due to its importance and high market prospect. Some of the advantages of catfish include adequate nutrition, fast and easy growth. Salinity is one of the water quality parameters which directly affect fish body metabolism and osmoregulation. Increasing salinity may affect energy utilization within the osmoregulation process. Salinity is one of the environmental factors that can affect the rate of growth and feed consumption. This experiment was conducted to understand how salinized media may affect growth rate, survival rate and feed conversion ratio (FCR). The most optimal salinity that affects the aforementioned parameter was also observed. The research method used Randomized Complete Design with four treatments and five replications. Treatments were given code P0 (0ppt), P1 (3ppt), P2 (6ppt) and P3 (9ppt). Data analysis was done using ANOVA followed by Duncan Multiple Range test. Results indicated that salinity difference had significant effect (p
