A Meta-Analysis Approach toward Fish Meal Replacement with Fermented Soybean Meal: Effects on Fish Growth Performance and Feed Conversion Ratio


This study applied a meta-analysis approach to quantify the effect of replacing dietary fish meal (FM) with fermented soybean meal (FSBM) on the final weight and feed conversion ratio (FCR) of fishes. The impact of 14 studies was examined with 53 comparisons between fishes fed with various inclusion levels of FSBM and control treatments. The FSBM inclusion levels of 8 % to 60 % resulted in mean effect size of -3.75 [95% confidence interval (CI) -4.49 to -3.01] for final weight and 1.26 [95% CI 0.58 to 1.94] for FCR. The FSBM inclusion level greater than 40 % decreases the final weight of fish compared to the control treatment of the studies. Meanwhile, inclusion of FSBM at the level of 15 % to 44 % improves the FCR of the diet and higher than 44 % produces an inconsistent result. The present study contributes to the FM replacement debate by presenting numerical values and providing strong conclusions compared to the common narrative reviews about partial or total replacement of FM with FSBM.
