THE EFFECT OF DIFFERENT QUALITY PELLETED FEEDS ON THE GROWTH OF GREEN CATFISH (Hemibagrus nemurus) IN FLOATING NET CAGE

ABSTRACT: The study was conducted to evaluate the different protein content of fish feed on the growth performance of green catfish (Hemibagrus nemurus). Two thousandfingerlings averaging 3.92±0.32 g of individual body weight were stocked in eachfloating net cage (3m x 3m x 3m) in Musi River, South Sumatra. They were fed daily forfour months with feed protein content of 27% and 31%. The feed was given in pelletedform 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 thesame for 2 treatments and ranged between 94.17%-95.18%
