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%
