The present study was undertaken to report the ichthyofaunal diversity on spring-fed hill stream Randi Gad from Pauri Garhwal District, Uttarakhand, India. In this work, the author proposed one novel approach, viz. stream order-wise study of distribution and diversity of fish fauna from Garhwal Himalaya, India. A total of 121 fish species including 4, 12 and 22 fish species were collected from first-, second- and third-order streams of Randi Gad. The ichthyofaunal biodiversity observed belonged to 4 families, 10 genera and 22 species. The first-order stream had shown minimum diversity (4 species) and fish productivity of 07CPPs. The second-order stream showed productivity of 24CPPs (12 species). The third-order stream was the most diverse (22 species) and showed fish productivity of 38 CPPs (calculated productivity points system). Thus, the spring-fed hill stream Randi Gad has good potential for fish fauna.
