Effects of the probiotic Bacillus amyloliquefaciens on growth performance, hematology and intestinal morphometry in cage-reared Nile tilapia

The aim of this study was to evaluate the effect of probiotic Bacillus amyloliquefaciens on the growth performance, blood profile and intestinal morphometry in Nile tilapia (Oreochromis niloticus) reared in cages. 936 Nile tilapias were distributed in 12 cages (1.5 m³). Fish were fed for 90 days on...
