Abstract: In this paper,a marked positive linear relation between the body length and the scale radius of the Megalobrama Skolkovii in the Nanshui reservoir was described. L =1.4322+45.7494 R , r=0.9531, n= 187. The results indicate that it belongs to regular growth.However,there is a slow growth in the second year,and in the sixth year.
