The study was conducted to evaluate the different protein content of fish feed on the growth performance of green catfish ( Hemibagrus nemurus ). Two thousand fingerlings averaging 3.92±0.32 g of individual body weight were stocked in each floating net cage (3 m x 3 m x 3 m) in Musi River, South Sumatra. They were fed daily for four months with feed protein content of 27% and 31%. The feed was given in pelleted form at 4%-8% of the total body weight. The result showed that the feed with 31% protein content gave better performance and significant different (P<0.05) than 27% protein feed. The feed content 31% protein was optimum for green catfish fingerlings and gave higher average individual weight gain (80.48 g), specific growth rate (2.67%), fat retention (29.48%) and better feed conversion ratio (2.28). Survival rates were the same for 2 treatments and ranged between 94.17%-95.18%.
