Electrophoretic and isoelectrophoretic behaviour of the hemoglobins of Italian freshwater Ictalurids was analysed. Multiple and polymorphic hemoglobin patterns were found in Ictalurus sp. (I. nebulosus nebulosus?, I. melas?); multiple and monomorphic patterns in I. n. marmoratus and I. punctatus. Hypotheses are advanced for further investigation of the question.
