The loni wetland is an important habitat for the different fishes such as IMC, Catfishes, Notopterus andother small indigenous fishes. The evaluation of conservation status of fish diversity will depict a picture ofwetland ecosystem for sustainable production, ecosystem health and enhanced productivity ultimatelyaddressing the social issues like livelihood, malnutrition and food security. Seasonal sampling was done,i.e. pre-monsoon; Monsoon and post-monsoon during 2018-2020 and collected fish samples from loni wetlandby using cast and drag nets. Fishes were brought to the laboratory after preserving in 5% formalin forfurther detailed identification. The diversity indices were calculated and assed the conservation status offishes. In the present investigation a total of 32 fish species, representing 24 genera, 7 orders, and 13 familieswere recorded for the first time. Order Cypriniformes (47%) contributed significantly among all followedby Perciformes (25%), Siluriformes (13%), Clupeiformes (6%), Beloniformes (3%), Mastacembeleformes (3%)and Osteoglossiformes (3%). The maximum fish diversity was observed in monsoon season (Hâ=3.001) ascompared with pre monsoon (Hâ= 2.918) & Post Monsoon (Hâ= 2.866).Out of 32 species there are 29 underLeast Concern (LC), 2 under Near Threatened (NT), 1 underVulnerable (VU)category.
