In the proposed project, a novel genetic method for monitoring will be applied using the example of the European smelt (Osmerus eperlanus), an economically important migratory fish species. Using NGS (Next-Generation-Sequencing) methods, SNPs (Single Nucleotide Polymorphisms) can be identified as genetic markers across the genome, which can be used to characterize differences between populations and even to resolve relationships between individuals. In the proposed project, these methods will be applied in the so-called CKMR method (Close-Kin Mark-Recapture), a completely new approach to population size estimation that is independent of fishery data. The exact relationships between individuals will be determined. The distribution and frequency of parent-child or half-brother and sister pairs in a population then allow conclusions to be drawn about the absolute population size. In addition, CKMR provides further parameters such as fertility and mortality that are important for an assessment of population dynamics. This novel genetic approach will be adapted to the European smelt and validated using classical population biology approaches. The rearing of smelt larvae under controlled conditions in experimental aquaculture will provide additional information on environmental factors that influence the survival and development of eggs and larvae.
