Electrophoretic band patterns for twenty commercially important British fish species have been obtained by electrophoresis of their muscle myogens on thin slabs of polyacrylamide gel. Since each band pattern is characteristic of one species and is practically unaltered as a result of ice storage or frozen storage of the fish, it is possible to identify any fresh and frozen fillet belonging to these twenty species by comparing its band pattern with the standards obtained. The method can also be used to identify two species of fresh fish in admixture. Cooked fish cannot be identified by this method.
