对北方加州外海的太平洋鲱鱼寄生虫进行了调查，鉴定出头形目1种，绦虫纲1种，桡足纲2种，复殖目1科1种，线虫纲3种，原生动物3种。从这次调查中，Lacistorhynchus dollfusi（Cestoda），Parahemiurus merus（Digenea）和Anisakis simplex，Contracaecum sp.，Hysterothylacium sp.（Nematoda）被选为潜在的标签。鲱鱼收集在Tomales，旧金山弗朗西斯科，和蒙特利海湾为以下9年，并检查这些选择的寄生虫。结果表明，这些寄生虫可以用来区分产卵种群的旧金山弗朗西斯科和托马莱斯湾。各自的寄生虫的最终宿主的分布表明，Tomales湾的鱼在非繁殖季节和岸上的旧金山弗朗西斯科湾的鱼离岸。旧金山弗朗西斯科湾和蒙特雷湾的nonspawning人口之间的寄生的相似性表明，这2个人口代表一个单一的股票。
A survey of the parasites of Pacific herring (Clupea harengus pallasi) off northern California identified 1 species of Acanthocephala, 1 species of Cestoda, 2 species of Copepoda, 1 species and 1 family of Digenea, 3 species of Nematoda, and 3 species of Protozoa. From this survey, Lacistorhynchus dollfusi (Cestoda), Parahemiurus merus (Digenea), and Anisakis simplex, Contracaecum sp., Hysterothylacium sp. (Nematoda) were selected as potential tags. Herring were collected in Tomales, San Francisco, and Monterey bays for the following 9 yr and examined for these select parasites. The results suggest that these parasites can be used to distinguish the spawning stocks of San Francisco and Tomales bays. The distribution of the definitive hosts of the respective parasites suggests that the Tomales Bay fish are offshore during the nonbreeding season and the San Francisco Bay fish onshore. The similarity in parasitism between San Francisco Bay and the nonspawning population in Monterey Bay suggests that these 2 populations represent a single stock.
