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, 118 03 E), Fujian, China. In laboratory, the oncomiracidia hatched from eggs in four to six days at 25 28 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 10 14 days at the room temperature (26 30 ). On t he sixteent h day, t he adult s began to release eggs. The fish host ( L iz a carinat us) is proved to be a new host record of N. worms and adults of this monogenean was described in this paper. gi rellae.
