Mitigation of Zinc Sulphate Induced Haematological Toxicity in the Fish Mystus montanus by Probiotic Bacteria

Abstract

The present study was designed to evaluate the zinc sulphate intoxicated haematological parameters of the fish Mystus montanus in two different sub lethal concentrations of ZnSO₄ and to analyse the effect probiotic bacteria Lactobacillus rhamnosus on the haematological parameters of the Zinc intoxicated fish for 60 days. Significant differences of altered blood parameters were observed (P<0.050) in the Full blood count, Haematological indices and Differential Leucocytes counts of fish treated with Zinc. However the fish group treated with probiotic bacteria showed significant tolerant ability for zinc induced hematological parameters. This research demonstrates that dietary supplementation of probiotic bacteria can cope up with zinc pollutants in the aquatic medium.
