To investigate Hysterothylacium aduncum (Anisakidae) infection in marine fishes from Bohai Sea and Yellow Sea.
Nematodes were collected from the digestive tract of fishes, fixed with hot 4% formalin and preserved in 70% ethanol for study. The specimens were cleared in lactophenol for light microscopical examination, and properly treated for scanning electron microscopy (SEM).
Among the fishes examined, 14 out of 93 species (15.1%) were found infected by H. aduncum, with a higher prevalence in the fish of Lophius litulon (66.7%), Scomberomorus niphonius (47.5%), and Gadus macrocephalus (33.3%). H. aduncum infection was first recorded in elasmobranch-Raja smirnovi. Morphological differences of H. aduncum were observed, including the width of lateral alae and the length of intestinal caecum.
H. aduncum in fishes of Bohai Sea and Yellow Sea in China may be a complex species, and its high prevalence in some fishes reminds the risk of anisakiasis by eating raw fishes.
调查渤海和黄海海洋鱼类中的异尖线虫（异尖科）感染情况。
从鱼类消化道采集线虫，用热的4%福尔马林固定，保存在70%乙醇中用于研究。标本用乳酸酚透明以进行光学显微镜检查，并进行适当处理用于扫描电子显微镜（SEM）观察。
在所检查的鱼类中，93种中有14种（15.1%）被发现感染异尖线虫，在黄鮟鱇（66.7%）、日本鲐（47.5%）和大头鳕（33.3%）中感染率较高。异尖线虫感染首次在板鳃亚纲鱼类——史氏鳐中被记录。观察到了异尖线虫的形态差异，包括侧翼宽度和肠盲囊长度。
中国渤海和黄海鱼类中的异尖线虫可能是一个复合物种，其在某些鱼类中的高感染率提示了食用生鱼导致异尖线虫病的风险。
