Abstract
Water is essential requirement for the fish they can’t live without water and quality of water plays an important role in the aquatic oriental fish culture. The physical and chemical parameters play major role for the survival of fish in the fish tank. The temperature reduced to 210C while the hydrogen ion concentration came down to 6.3. The total oxygen level found 6.3 and the hardness of water reached to 105.1mg/ml. The water quality was found contaminated with Escherichia coli and Micrococcus sp. The fish found died due disease caused by Pseudomonas sp, Vibrio sp and Staphylococcus sp. The extracts of mango leaves showed good antibacterial activity against both water bacterial isolates and diseased fish bacterial isolates by showing zone of inhibition against the bacterial isolates. Thus, showing that mango leaves can be used as an antibacterial agent in the ornamental aquatic fish cultures to prevent the disease.
