Abstract
A total of 60 indigenous ornamental fish species was recorded. Cyprinidae was the dominant group representing 20 species followed by Bagridae, Channidae and Cobitidae. The statistical relationship between ornamental fish abundance and important physico-chemical attributes showed strong and positive correlation. The Shannon-Wiener diversity index indicates richness of ornamental fish species with an overall index of 3.65.
Key words: Indigenous ornamental fish, diversity index, river Brahmaputra
