Author(s): K. Sivakumar, Janani D, Shree Rama M
Abstract: The study of microbiota of ornamental fishes gives the view on both pathogenic and beneficial strains in fish gut. Total of nine bacterial strains were isolated from four different ornamental fishes namely Cichla ocellaris, Barbonymus schwanenfeldii, Parachromis managuensis and Cyprinus carpio. From the results, analyzing the dominance and microbial diversity of four different fish it is shown that Cyprinus carpio has highest dominant bacterial load and Barbonymus schwanenfeldii has highest microbial diversity. Out of these nine strains, strains like Vibrio metschnikovii, Vibrio cincinnatiensis, Aeromonas veronii and Micrococcus halobius indicated the constant evolving aquatic ecosystem surrounding the fishes. Since the probiotic is one of the strains which is present in the gut micro flora, it enhances and helps in the betterment of the growth of the fishes. This work promotes the use of these gut microbial microorganisms as probiotics and to render the fishes a disease free growth.
