Abstract

Since 1977 larvae surveys have been carried out in the Greifswalder Bodden and the Strelasund every year to estimate an index of the year-class strength for the western Baltic herring stock. Different methods have been used to minimize the very extensive analytical work in the laboratory since 1993. As a further possibility the use of the mean dry weight of the larvae was investigated. This method was applied successfully to estimate the number of eggs in cod gonads. 88 samples of herring larvae were analysed. These experiments show that the use of the mean dry weight of herring larvae is not suited to reduce the work in the laboratory, because the accuracy of the estimates is unacceptable.
