Effect of Bacillus subtilis on the growth and survival rate of shrimp (Litopenaeus vannamei)

The effect of Bacillus subtilis, isolated from digestive tract of Macrobrachium rosenbergii was investigated on growth and survival rate of Litopenaeus vannameiduring 60 days of culture. Sixteen aquaria with four replicates were used for treatments and controls. Treatment groups were consisted of і)...
