title: The use of electrophoresis of the water-soluble (sarcoplasmic) proteins of fish muscle to differentiate the closely related species of hake (Merluccius sp.).
abstract: 1. Electrophoretic separation patterns of water-soluble proteins of five species of hake, Merluccius merluccius; M. australis; M. productus; M. bilinearis and M. angustimanus, have been examined. 2. The patterns were reproducible within each species and distinguishable from one another. 3. The frequency distribution of numbers of vertebrae and of gillrakers were obtained for the same fish. 4. Only the electrophoretic patterns gave an unequivocal identification of the species.
