The external morphology of diploid and triploid grass carp was studied to determine whether the two types could be separated by differences in external characteristics. In a comparison of 27 measurements, six scale counts and five fin formulae from two stocks of diploid and triploid fish obtained from commercial producers, analysis of covariance and discriminant analysis indicated a classification accuracy of only 65-85%. Clearly, triploid grass carp differentiated by external morphology alone should not be stocked into waters where diploid fish are illegal or would cause management problems.
