Description 
Summary

The international Herring Larvae Surveys (IHLS) are carried out between September and end of January in the north-western, central, and southern North Sea and Eastern English Channel, following the spawning areas of North Sea herring. The surveys aim to provide quantitative estimates of North Sea herring larval abundance, thus targeting the very young stages of freshly hatched herring in the vicinity of the spawning areas.
