To investigate the effect of turbid water on fish population, the length-weight relationship and its condition factor were applied to Kumgang fat minnow Rhynchocypris kumgangensis collected in turbid (the Daegi and the Jaun streams) and non-turbid stream (the Bongsan and the Gyebang streams) for a year from 2004 to 2005. The mean length of minnow between turbid water and non-turbid water streams was not significantly different. In the South River system, the regression coefficients (b) based on length-weight relationship were 3.21 in the non-turbid Bongsan stream and 3.07 in the turbid Daegi stream, respectively. On contrary, the regression slope in the turbid stream was a little higher than that of the non-turbid stream located in the Bukhan River system. The values were 3.20 in the Gyebang-stream and 3.23 in the Jaun stream, respectively. Our result suggested that chronic turbid water effect on the level of fish population has a little or no effect.
