All eggs used for this study were obtained from the parasites on the body surface of amberjack fry ( Seriola dumerili) collected in floating sea cages, in Xiamen (24 29 N, E), Fujian, China. In laboratory, the oncomiracidia hatched from eggs in four to six days at in salt water. Then, the oncomiracidia were used to infect the fish ( L iz a carinat us) in laboratory. After attaching to the skin of the fish host, the oncomiracidia developed to adult in days at the room temperature (26 30 ). On t he sixteent h day, t he adult s began to release eggs.
