Abstract: During the last century, riverine ecosystems have affected from intense human interference resulting in habitat loss and degradation and as a consequence, many fish species have become highly endangered, especially in rivers. In my present study three sampling stations were selected along the stretch of river Rupnarayan at Kolaghat. Moreover, Kolaghat thermal power station is located on the right pool of this river. Monthly sampling was collected at three sampling stations (S1, S2 & S3) during July 2015-June 2016 by using gill nets and brought about to the laboratory and analyzed with the standard methods. Total 38 species of fishes belonging to twenty four sub- families and 9 orders were collected from the selected sampling stations. The Shannon- Weiner diversity index of three different sampling indicated a strong relationship with overall species richness, showed variation and ranged from 3.052 –3.278 . The highest fish diversity were recorded at station –I followed by station – III and II. The most abundant fish species was Ambly pharyngodonmola (8.3%) and Polynemus paradiseus (7.7%) were recorded. The order Siluriformes (29%) found to be dominant with 12 fish species followed by Perciformes (25%) with 11 species and Cypriniformes (21%) 5 species. Conservation status revealed that there are only four species that was under near threatened (NT) category. Apart from this remaining species represented least concerned (LC) and only few species are not evaluated (NE). In this study an attempt has been made to evaluate the fish-faunal diversity in the region and suggests mitigating measures.
Keywords: Abundance, conservation status, fish-faunal diversity, species richness, near threatened.
