Litopenaeus vannamei fed diets with different replacement levels of fish meal by fish silage: A molecular approach on intestinal microbiota

Abstract

We investigated the intestinal microbiota in shrimp fed diets with five replacement levels (0, 25%, 50%, 75% and 100%) of fish meal by fish silage. An 8-week feeding trail was conducted in 15 fibreglass tanks (400 L volume, three replications for each diet) with 50 shrimps (initial weight 0.26 +/- 0.03 g) per tank. After 8-week trial, shrimp fed diets with low replacement levels (0% and 25%) of fish meal by fish silage had significantly enhanced growth performance (p 0.05), which indicated the limited impact of dietary fish silage on intestinal microbiota.
