Oncomiracidial development of Sparicotyle chrysophrii, a monogenean parasite of Sparus aurata, was analysed using 450 eggs. Parasite morphological changes in time, data on hatching success, as well as oncomiracidial survival and swimming behaviour were recorded. Eggs were maintained at 20 °C and exposed to LD 12:12. They were observed under the stereomicroscope every 8 h until they hatched. Thereafter, 155 oncomiracidia were isolated in separate wells and observed every 2 h until their death. The complete life cycle of S. chrysophrii (from egg to egg) at 20 °C lasts approximately 50 days: 5–10 days of incubation, 2–3 days of oncomiracidial survival time and 36 days of worm maturation. Treatment involving two applications, first for adults and juveniles and later (after 12 to 15 days) for larvae, would allow long periods without monogenean infection.
