| We assessed the physical habitat conditions of pale chub (Zacco platypus) considering various stream order in the Geum river basin. Field monitoring was conducted for ecological and habitat conditions for 28 sites from October 2007 to October 2008. The number of Z. platypus sampled during this period was 2,362. In more than 3rd stream, water depth and velocity showing the highest number of samples were 0.8 m and $0.8;m;s^{-1}$, respectively. In addition, the highest number of samples was observed under the condition of total length (TL) (8~10 cm), velocity ($0.3;m;s^{-1}$), water depth (0.4 m), substrate size (send, 0.1~1.0 mm~coarse gravel, 50.0~100.0 mm) and habitat type (run). Based on the monitoring data (n=1059) the relationship between body weight (BW) and TL in male and female were estimated as $BW=0.0068{ imes}TL^{3.0274}$ ($r^2=0.9102$) and $BW=0.0075{ imes}TL^{2.9995}$ ($r^2=0.8517$), respectively. Growth equations on days after parturition (DAP) to the TL were estimated as TL=0.0108DAP+1.5795 ($r^2=0.9721$). By equations (TL 6.9 cm), BW were 2.7 g (male) and 2.4 g (female), and DAP was about 490 days. |
