Abstract

Occurrence and distribution of parasitic Copepoda (Crustacea) off the southern coast of South Africa.

Abstract

Approximately 25 fish species were examined for parasitic copepods during a survey of southern Indian Ocean fish population. 11 species of parasites, i.e. Chondracanthus merlucci, Lernentoma asellina, Medesicaste penetrans, Caligus tetrodontis, C. coryphaenae, C. infestans, Lepeophtheirus longispinosus, Achtheinus oblongus, Perrisopus armatus, Charopinus dalmanni and Brachiella supplicans, were found to infest fish. Hake (Merluccius capensis) was especially heavily parasitized by for example Medesicaste penetrans, which in some localities had a prevalence of 43%. Two sharks, especially bluntnose spiny dogfish (Squalus megalops), were as much as 29% infested with P. armatus. Two parasite species, A. oblongus and C. dalmanni are recorded from this region for the first time.
