1. Six proteins, haemoglobin (two loci), serum esterase (two loci) and lactate dehydrogenuase (two loci) from two species of jack mackerel, Trachurus declivis and T. novaeselandiae, were compared electrophoretically. All six loci were found to be monomorphic. 2. LDH from red and white skeletal muscle tissue were electrophoretically different, but the red form and the white form were found to be identical in both species. 3. Both species share an electrophoretically identical serum esterase, but each species also has an electrophoretically distinct serum esterase. 4. Both species share an electrophoretically identical haemoglobin, but each species also has an electrophoretically distinct haemoglobin. 5. The otolith iron contents of the two species were compared and found to be identical.
