present status of fish species diversity of Surma River at Sylhet Sadar, Northeast Bangladesh. A total of 51 fish species belonging to 16 taxonomic families has been identified. The most abundant family was recorded as Cyprinidae covering 36%, while the least abundant family was Gobidae and Plotosidae comprising 1%. A Shannon-Weaver diversity index was fluctuated between 2 to 2.5 with mean value 2.30±0.14, which reveals exposer to light pollution in study area. The peak Pielou’s evenness index value was 2.2 in April and the lowest value 1.47 in July with mean value 1.93±0.23. Maximum value of Simpson dominance index is 7.98 in August and minimum value 5.32 in October with mean value 6.99±0.86. The catch per unit effort ranged from 0.15 to 0.48 with an average value of 0.34±0.11.
