Caging study - Kollevåg

The goal of the dCod-project is to combine the competencies in environmental toxicology, biology, bioinformatics and mathematics across the traditional department boundaries, to create a deeper understanding of cods' adaptations and reactions to stressors in the environment. Building on the thoroughly studies and mapping of the cod genome at UiO and the long research traditions on cod at the Department of Biology at UiB, the dCod project will expand our knowledge with methods based on genomics; ...

Coastal zones and oceans constitute an essential fundament for Norway’s history as well as current economy, providing ecosystem services for fisheries, aquaculture, transport, tourism, and recreation. The petroleum activities in Norwegian waters have been crucial for Norway’s financial growth and in financing the Norwegian welfare state. As the pressure on the oceans continuously increases, both the petroleum industry and the seafood industries have acknowledged that awareness and actions are ...
