A new study has shown that there are different types of European cisco in Swedish waters that are each genetically adapted to fresh, saline or brackish water. Genetics also steers where European cisco spawn. The new knowledge from this study can be used in continuing the sustainable management of the species, and for investigating whether the spawning environment affects the quality of the roe.
An international team of Swedish, Norwegian, Danish and Irish scientists has used whole genome sequencing to characterise 53 herring populations from the Atlantic Ocean and the Baltic Sea. They have developed genetic markers that make it possible to better monitor herring populations and avoid overfishing. The study is published in the journal eLife.
How species genetically adapt to their environment is a central question related to the evolution of biodiversity. In a new study scientists at Uppsala University and their colleagues report that whole genome sequencing of Atlantic and Baltic herring revealed hundreds of loci underlying adaptation to the brackish Baltic Sea or timing of reproduction. The study is published today in eLife.
