Abstract
The analysis of an infestation level of the Baltic herring (Clapea harengus L.) with Anisakis simplex (Rud.) larvae as well as otoliths and gonad maturity examinations allowed to distinguish, among the Pomeranian Gulf and adjacent area herrings, 4 herring stocks appearing successively in the region investigated. The seasonal occurrence of Anisakis larvae in herring from the examined fishing regions is related to the sequence of arrival of the different stocks. Suspected sources of invasion are discussed, the Anisakis invasion being related to the North Sea herring migrations.
