Abstract
Flow cytometry was used to identify polyploid fish by means of measuring deoxyribonucleic‐acid fluorescence in erythrocytes. One polyploid grass carp Ctenopharyngodon idella and one polyploid bighead carp Hypophthalmichthys (=Aristichthys) nobilis were identified among 38 fish of each species. Ten hybrids identified as diploids on the basis of morphology were confirmed to be diploid. All hybrids identified as polyploid morphologically were indeed polyploid, but two of these were tetraploid rather than triploid. Received May 14, 1982 Accepted February 15, 1983Keywords
