Abstract(s)
The metazoan parasites of four populations of the chub mackerel Scomber japonicus were
analysed from two localities in the Atlantic Ocean (Madeira Islands, Portugal, and Rio de
Janeiro, Brazil) and two localities in the Pacific Ocean (Callao, Peru, and Antofagasta, Chile),
collected during 2002 and 2003. A total of 373 fish specimens were studied and 34 metazoan
parasite species were obtained. Parasites identified from the populations of chub mackerel
studied could be separated into three categories: parasites with a wide distribution, present in
the Pacific and Atlantic, parasites proper of the Pacific Ocean and parasites proper of the
Atlantic Ocean. The analyses of some highly specific parasites of the genus Scomber (i.e.
monogeneans of the genus Kuhnia and didymozoid digeneans) strongly suggest the need for
a revision of the taxonomic status of chub mackerels from the Atlantic and Pacific coast of
America. The results demonstrated the usefulness of parasites as adequate tools to clarify the
taxonomic status of their hosts.
