Dr. Bhatt Nakul A, Dr. BK Sharma

The present study on “An assessment of the biotic and abiotic components of the Lake Udai Sagar Ecosystem, Udaipur, Rajasthan” was conducted during September 2016 to September 2017. The lake has a fairly rich fish fauna and so far 20 species representing 7 families have been recorded in the present investigation, of these, 9 species predominantly contributed to the commercial fisheries of this lake. In the present water quality features such as air and water temperature, transparency, pH, alkalinity, free carbon dioxide, dissolved oxygen, primary productivity, electrical conductivity, nitrate-nitrogen and orthophosphate were done along with qualitative and quantitative estimation of phytoplankton. The study indicated that the average primary productivity (GPP) of Lake Udai Sagar was found to be 0.52.0 g C m3 h-1 in the surface. During the study period, the Indian major crops dominated the catch by contributing 90 percent of the total landings from this lake. Besides Indian major carps, minor carps and catfishes were reported to be 8.84 and 0.9 percent, respectively. Among the Indian major carps, the Catla catla (70%) dominated the groups followed by Labeo rohita (25%) and Cirrhinus mrigala (5%).
