Sex ratio ofChanna punctata (Bloch, 1793) (Pisces, Teleostei, Channidae) from Guntur, Andhra Pradesh
The sex ratio ofC. punctata has been studied over a two-year period. The Chi-square test was applied to test the significance of the differences in the proportion of males in the monthly samples of each year and ascertain whether the observed sex ratio differs significantly from the theoretical 1 : 1 ratio. The data show that in most length groups males outnumber females. The relation between the age and length attained by the two sexes has been discussed.
