THE LENGTH/MASS RELATIONSHIP AND CONDITION OF LABEO CAPENSIS IN THE CALEDON RIVER

Abstract

The length mass relationship for a Labeo capensis population is described by the equation M = 0,0134 L^2'999 where 2,999 represents a constant the value of which indicates isometric growth. There is very little difference between the length/mass relationship for males and that for females and this is similar to the results found by Mulder (1973) for L. capensis in the Vaal River. The length/mass relationships for gravid males and females are different from that of the population as a whole indicating that maturity does result in a change of the body form which is in accordance with the results of Mulder (1973).
