Studies on the ameliorative effects of a probiotic consortium on normal and Aeromonas hydrophila -infected freshwater fish, Labeo rohita

This present study was carried out, the use of probiotic consortium in freshwater aquaculture to be highly effective in improving disease resistance, survival, growth and nutrition. In this probiotic consortium was used for different concentrations of the fish feed such as 1%, 3%, and 5%. We have shown that Labeo rohita fed a probiotic supplemented diet have an improved survival and growth in 60 days culture animals every 20 days Aeromonas hydrophila infected in fish. Maximum weight gain (21.6g) was observed after 60 days in 5% probiotic fed animals. The maximum protein content in (32.5 mg %) was observed in muscle after 60 days animals. Increasing in WBC cells in infected animals which probably indicated increased in disease fighting capability of the fish. The general conclusion obtained from the present study is that the probiotics play a vital role in growth survival, protein, and glycogen, enumeration of blood cells and protein separation of the animals compared to control animals. The supplementation of the probiotic consortium diet is probably effective for rearing conditions.
