title: [Morphological and taxonomical studies on anisakidae larvae found in marine fishes of China. II. Gulf of Tong King].
abstract: A survey on Anisakidae larvae in 29 species (134 specimens) of marine fishes in the Gulf of Tong King has been carried out. Anisakidae larvae were detected in 15 out of 29 species. The detected specimens were identified as larvae of Anisakis simplex, Hysterothylacium and Pseudoterranova. The parasitization rate of Anisakis simplex larvae, the main pathogen of anisakiasis, in fishes was 30.6% (41/134), while the parasitization rates of Hysterothylacium and Pseudoterranova larvae were comparatively low. Hysterothylacium larvae China type I detected from Muraenesox cinereus and Trichiurus haumela was a new record. Their morphological characteristics were summarized as follows: 1. Length 10.78-14.18 mm, Width 0.25-0.38 mm, the length of the esophagus is 1.14-1.73 mm, intestinal cecum 0.77-1.24 mm and ventricular appendage 6.27-8.40 mm, extending parallelly with the intestine to the last quarter of the larva; 2. Boring tooth was present, but mucron was absent; 3. No genital anlage was observed.
