Abstract:

The present study was made to find out the health status of a wetland Rajar Beel, North 24 Parganas, West Bengal, India in relation to physicochemical properties of water. This wetland is rich in aquatic biodiversity. The study focused on the seasonal fluctuation of physicochemical parameters of water and diversity of fish fauna during pre-monsoon, monsoon and post-monsoon during March 2019 to February 2020. Water samples and fish specimens were collected from three different sites of the beel every month to evaluate the correlation between physicochemical properties of water and the indices of fish diversity. A significant seasonal fluctuation in fish diversity in relation to physicochemical parameters (temperature 23-30ºC, turbidity 18.5-26.5 cm, pH 7.1-8.4, CO2 0-40 mg/l, DO 4-7 mg/l, TA 155-218 mg/l, TH 105-186 mg/l, phosphate 0.15-0.41 mg/l and nitrate 0.03-0.15 mg/l of water) was recorded during the study period. In respect of fish faunal diversity, a total of 37 species belonging to 9 orders and 22 families were identified. Maximum representatives belong to order Cypriniformes having 7 species with 43.91% catch composition, whereas Perciformes with 15 species with 28.93% catch composition. The beel was heavily infested with aquatic vegetation creating complex environments for the growth of different faunal populations. The present study indicates that the beel is moderately productive and suitable for commercial aquaculture. This study will be helpful in the determination of the health status of the beel. The effect of seasonal variations on the assemblage of fish composition is found to be important and it should be considered into account when developing initiatives will be taken in the future to support the productivity and biodiversity of the wetland.
