The present assessment was intended to investigate the diversity of fish species and physico-chemical parameters of Ratabeel wetland located within a geographical location of 220 54’ 19.5” N and 92027’ 48.4” E in Karimganj district of Assam. The physico-chemical parameters include Air Temperature (AT), Water Temperature (WT), Turbidity, pH, Dissolved Oxygen (DO), Free Carbon-di-Oxide (FCO2), Total Alkalinity (TA), Total Hardness (TH), Conductivity (Cndvty), Nitrate (NO3), Phosphate (PO4) etc. and were estimated by following standard procedure of American Public Health Associatio (APHA). During the study period, the fish species were collected by using different experimental fishing gears such as a variety of traps, cast nets, gill nets, drag nets, triangular scoop nets etc. and then identified by following standard literature and keys. During the assessment period the values of physic-chemical parameters were found to be within the range of WHO standards portraying the better condition of the habitat for the fishes. The ichthyofaunal diversity study of the wetland revealed 43 species of fishes belonging to 35 genera, 14 families and 7 orders. Among them the fishes of the order cypriniformes (48%) were found to be abundant followed by Siluriformes (27%), Perciformes (15%), Osteoglossiformes (4%), Clufiformes (2%), Synbranchiformes (2%) and Beloniformes (2%).
