An investigation of Anisakis simplex larvae,the most important causative agent of anisakiasis,in marine fishes caught in Bohai sea was carried out in order to detect their infectivity.
Although early instar larvae were present in the host larval hemocoel, only one parasitoid survived to come out of host larva for pupation, killing the larva in the process.
5 to 7 days' larve after hatching larvae mostly lived on copepod nauplii, copepodites and trochophore of Polychaeta in water of the earthen ponds, apart from feeding on particulate organic detritus.
Compared with the D-larvae and the umbo-larvae, the densities of the post larvae and the settled spats show rapid reductions at the end of the development process.
