Scale surface morphology provides new and useful information on fish taxonomy. Several characters of scales are established and being used as a taxonomic tool. Scales in three teleosts species were observed and measured from eight regions of fish body that represented different size, shape and characters. From the results, it was concluded that scale morphology and its surface patterns can be valuable tools to investigate systematic relationship among the fish species, scale structure is also useful to recognize food chain in aquatic ecosystem which will be helpful to maintain and conserve different components in freshwater food chain.
