The Effect of Probiotics on Growth Performance, Haematological and Biochemical Profiles in Siberian Sturgeon ( Acipenser baerii Brandt, 1869)
The use of probiotics in aquaculture has become a necessity to increase disease resistance. Probiotics are also capable of increasing feed digestion and conversion, decreasing sensitivity to stress, and improving the health of the fish. The aim of this study was to analyse the effect of probiotics o...

The use of probiotics in aquaculture has become a necessity to increase disease resistance. Probiotics are also capable of increasing feed digestion and conversion, decreasing sensitivity to stress, and improving the health of the fish. The aim of this study was to analyse the effect of probiotics on survival, welfare, growth indices and blood composition in Siberian sturgeon ( Acipenser baerii ), reared in a recirculating system. Diets were supplemented with Lactobacillus acidophilus (FLa) and Saccharomyces boulardii (FSb), separately and combined (FLa + Sb).
