The commercial fishing in Nanak Sagar reservoir is carried out using traditional types of gears viz. gill net, triangular net, drag net, hooks and lines, cast net and rod and line. From the gear, the gill net was most commonly used to harvest the fishes. The fish fauna of Nanak Sagar reservoir mainly consists of a rich assemblage of forage fishes, residual cat fishes, minor carps, exotic carps and some amount of major carps. Among fishes, Gadusia chapra with mean annual contribution of 44.14% was the most dominant fish species in the catches. Labeo gonius with a contribution of 15.95% was another quantitatively dominant species during the study period. Among Indian major carps Cirrhinus mrigala was the most abundant. The Cat fishes and minor carps were also present in appreciable numbers in the fishery of the Nanak Sagar reservoir. Maximum and minimum fish catch was obtained in the month of February, 2017 and September, 2016 respectively.
