Abstract

Five of 26 flathead mullet (Mugil cephalus) captured in the Seekoei River estuary in South Africa showed haemogregarine infections. Both trophozoites and gamonts were observed, and image analysis technology was used in parasite morphometric description. Gamonts were compared with those of Desseria mugili from Brazil and found to be different. The parasite mostly closely matched a haemogregarine previously illustrated, but not described from South Africa, and apparent lack of merogony suggested that it was a species of Desseria.
