LENGTH-WEIGHT RELATIONSHIP IN FRESHWATER CAT FISH CLARIAS BATRACHUS (LINN.)

Abstract

Clarias batrachus (Linn.), a common freshwater cat fish of Bhima river, has high economic
value and considerable fishery importance. The length-weight relationship in the logarithmic way
for this fish can be written as: Log W = 4.503717819 + 2.70681765 Log L This is close to the cubic
law indicating the isometric growth of the fish in its natural habitat. The correlation coefficient (r)
was found to be 0.9824 which showed a good relationship between the two parameters.
Keywords: Clarias batrachus/ length-weight relationship, Bhima river.
