European cisco – genetic adaptation to variation in salinity and spawning time
Many people view European cisco roe as a delicacy. 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 when European cisco spawn. The new knowledge from this study can be used in sustainable management of the species, and for investigating whether the spawning environment affects the quality of the roe. The study was conducted by researchers at Uppsala University, the Swedish University of Agricultural Sciences (SLU), the Royal Institute of Technology in Stockholm (KTH), Stockholm University, and the Museum of Natural History, and was recently published in the journal Molecular Ecology.Peer-review/Observational study/Animals
