Abstract

A feeding trial was conducted to evaluate the effect of fermented soybean meal and scallop byproduct blend 32 FP on the performance of juvenile red sea bream Five isocaloric diets were prepared by replacing 0 FP0 15 FP15 30 FP30 45 FP45 and 60 FP60 fishmeal FM protein with FP respectively Triplicate groups of fish initial mean weight 283 g were fed the test diets for 45 days in a flowthrough seawater system The results demonstrated that growth rates of fish fed FP0 FP15 and FP30 were similar and significantly higher P  005 than those of FP45 and FP60 Nutrient utilization was significantly lower in FP60 with no differences found among the other groups Dietary heavymetal contents were affected by inclusion of FP impacting on wholebody heavymetal contents In terms of oxidative stress fish fed the FP30 diet were in the best condition since this fish group showed the least oxidativestressed condition as well as the highest tolerance against oxidation In conclusion the approach of utilizing this fermented mixture is promising and it could replace at least 30 FM protein in red sea bream diet without negative effects on performance body composition or health of fishThe authors would like to thank AFCEP Japan for providing fermented soybean meal and scallop byproduct blend Profound regards to Professor Dr Jiro Koyama and technical stuffs at the Faculty of Fisheries Kagoshima University Japan for their assistance in performing the heavymetal analysis The authors thank the anonymous reviewers for their constructive comments and Miss Bo Causer for her reading of the manuscript This research was supported in part by the Ministry of Education Culture Sports and Science and Technology MONBUKAGUSHO Japan
