There is a need for robust stock discrimination tool for herring (Clupea harengus) in NE Atlantic, which we aim to develop in this project and to make use of. The ability to distinct fish of same species into different stock units in catches and research surveys is fundamental for stock assessment and sustainable management. Furthermore, fishery surveillance and international markets call for focus on generating new frameworks for identifying, mapping and monitoring the dynamics of fish stocks to tackle illegal, unreported and unregulated fishing and changes in migration due to climate change. In this international collaborative project, which involves five national institutions and a fishing company, DNA samples will be secured from spawning grounds of at least five herring stocks in NE-Atlantic and their feeding grounds where they are often found mixed. The samples will be genotyped with panel of 59-96 already developed single nucleotide polymorphisms (SNPs) related to spawning time. Statistical analyses will address the degree of genetic differentiation and the stock structure. The expected outcome of this project is therefore a robust method for stock differentiation resulting in improved fishery assessment and management (assign and assess fish to appropriate stock units), fishery surveillance (e.g. allocating catch compositions to appropriate stock units) marketing of fish products (i.e. traceability of products), and novel contribution to fisheries ecology.
