Different clupeid larvae surveys are carried out on the Northeast Atlantic
Shelf and provide essential data for the assessment of fish stocks in the North Sea, Irish Sea
and the Baltic.
In recent years other clupeids besides herring are
occurring in the survey samples in increasing numbers. Since clupeid larvae can easily be
mixed up, effective quality control and proper larvae identification is essential for reliable
survey results. These identification
workshops are repeated regularly in order to maintain the level of identification for the experienced as well as to train and
improve the skills of new survey participants.
