Abstract
An 12-weeks experiment was conducted to study the effects of dietary protein, lipid levels and vegetative ingredients replacing fish meal on growth performance of Marble Goby (Oxyeleotris marmoratus).
Experiment I, 9 formulated diet with 3 levels of digestible protein (CP 50%, 45%, 40%) and 3 levels of digestible lipid (CL 6%, 9%, 12%) were fed to Marble Goby for 12 weeks (initial weight: 10.34±2.11g). Weight gain (WG), body and liver lipid content of fish increased with increasing dietary protein level and lipid level.
Experiment II, to examine the replacement of the fish meal with vegetative ingredients at various levels in practical feeds for Marble Goby, replacing fish meal with by 0%、5%、10%、15%. After 12 weeks feeding trial, final body weight(FBW), weight gain (WG), Feed conversion rate decreased with increasing replacement of the fish meal with corn protein.
The data suggest that marble goby can thrive on a wide range of protein and lipid levels. In terms of economic and environmental concerns, and ability to maintain the rapid growth rate of this fish, the dietary protein can be lowered to 40% with higher lipid content.
