Abstract

Of 125 phenotypic walleye screened by isozyme electrophoresis, one unusual individual was detected and subsequently suspected of being a walleye (Stizostedion vitreum vitreum) x sauger (S. canadense) hybrid. The isozyme pattern obtained for L-iditol dehydrogenase (IDDH, E.C. 1.1.1.14), phosphoglucomutase (PGM, E.C. 5.4.2.2) and a fast migrating aspartate aminotransferase (AAT, E.C. 2.6.1.1) isozyme showed that this individual had both walleye and sauger isozymes. Isozyme analyses is a useful technique for distinguishing walleye x sauger hybrids from parent species. This is the first report of alleles of the AAT* locus being species specific for sauger and walleye, and the first confirmed report of naturally occurring walleye x sauger hybrids in Minnesota.
