Abstract

Nemacheilus moreh, is a small fish which plays vital role in torrential ecosystem and contributes immensely in fish biodiversity. Though it is not productive and economically important, it is pretty common in river Mutha and tribal people, and the "Katkari" catch them from commercial point of view. The logarithmic regression equation obtained for N. moreh male is Log W = -5.444 + 3.263 Log 1. and Log W = -4.713 + 2.957 log 1 for female. The coefficient of correlation for male was r = 0.988 and for female r = 0.989 respectively, which show a good relationship between the measurements of length and weight. The result indicate the cubic law (n = 2.957) in female for isometric growth. In male there is slight departure from cubic relation (n = 3.263). This may be due to intense feeding or due to early sexual maturity in male. The flactuation of Kn values of males and females for different size groups showed similar trends. The average Kn value of Nemacheilus moreh is 0.834 0.173, show well-being in its natural habitat.
