Abstract:
Sex ratio indicates the proportion of males and females in the population and is expected to be 1:1 in nature. In the present study, sex ratio of two commercially important fish namely Cyprinus carpio var. communis and Schizopyge niger has been studied for a period of one year from August 2018 to July 2019 from Dal lake, Kashmir. The study revealed that sex ratio (Male: Female) varied from 5.00:0.20 (July) to 1.14:0.83 (October) in C. carpio. The ratio for the entire period of study was 2.05:0.49 (Male: Female) indicating a significant dominance of males. In case of S. niger, sex ratio (Male: Female) varied from 0.20:5.00 in January to 0.88:1.14 in March. The sex ratio for the entire period of study was 0.48:2.07 (Male: Female) indicating a significant dominance of females.
