Sex ratio of Noemacheilus montanus (Mcclelland) from Pithoragarh district, Uttarakhand, India

The present paper deals with the sex ratio of Noemacheilus montanus (Mc.Cl.) from Pithoragarh district, Uttarakhand, India. The Noemacheilus montanus is a beautiful loach in this region. The sex population of Noemacheilus montanus, found a significant sex ratio in 1male:1.22 female. On the basis of observations it is concluded that the sex population of Noemacheilus montanus (Mc.Cl.) from almost all the localities female fishes are dominated. During the overall investigation on the Noemacheilus montanus (Mc.Cl.), the sex population was observed nonsignificant i.e. 1 male: 1.22 female. The chi-square value also showed 3.84 which are non-significant at 5% level.
