Abstract

The suitability of a combination of soybean meal (SBM), corn gluten meal (CGM), and meat meal (MM) as an alternative protein ingredient for fish meal in high energy dry pellet (DP) was examined for adult and juvenile red sea bream, Pagrus major. Fish weighing 565g and 35g on average were fed the experimental pellets containing combinations of SBM (20-30%), CGM (5-20%), and MM (3-6%) (replacing 42-62% of fish meal), for 85 and 56 days, respectively.<BR>Adult fish fed all the combination diets showed the same growth rate and feed gain ratio as the control. In the case of juveniles, However, fish fed the diets containing CGM above 15% showed inferior performance and hemochemical characteristics.<BR>These results demonstrated that a combination of SBM, CGM, and MM can succenfully replace 46-62% of fish meal in the DP for both adult and juvenile red sea bream though the CGM level should not be over 10% for juvenile fish.
