title: Isozymes of glucosephosphate isomerase (PGI) in fishes of the subclass actinopterygii.
abstract: A compilation of the species of fishes of the subclass Actinopterygii for the study of the PGI isozyme system is given. PGI appears to be codified by more than one locus in fishes; 65% of the species analysed here have two loci for PGI. PGI duplication in fishes and the relationship of isozymes of PGI with temperature and metabolism are discussed.
