Start year 2011 End year 2014 Funding (€) € 935,010 Website https://prosjektbanken.forskningsradet.no/en/project/FORISS/207547 Summary The current project aims to study whether the use of all-female triploid (3N) cod can be a solution for environmentally sustainable cod farming that is acceptable in terms of fish welfare. We propose a strategy where we produce 3N cod under assumed ideal conditions using natural zooplankton in the first feeding period to verify if we can achieve 3N cod juveniles with high growth potential and low incidence of deformities, and in parallel develop an improved and adapted intensive first feeding strategy for 3N cod for industrial relevance and later implementation. We will test the different 3N groups under optimal and extreme environmental conditions to establish a potential safe range for 3N rearing conditions, and also test the degree of sexual development in all-female 3Ns. We will study aspects of respiratory physiology, as this is believed to be one of the limitations of 3N fish. This will be done by including ongoing 3N cod activities at the collaborating institutes, including 2 PhD projects and the cod sibling group production in the National Cod Breeding Program at Nofima, Tromsø. The 3N approach will be combined with all-female production in some of the groups, as we have produced sex reversed females that develop both sperm and eggs, and the sperm from these hermaphrodites give rise to 100% females. The project will organize an international workshop in 2011 for invited scientists and stakeholders on the state-of-the-art of sterile fish with relevance for cod farming, in order to disseminate current knowledge, receive input for potential refinement of research activities, and identify critical factors for commercial implementation of 3N cod in farming. If successful, the project will provide the knowledge platform and the technology for economically and environmental sustainable cod farming, notably by preventing genetic impact on wild cod stocks and greatly improving productivity in cod farming, and thus be a major breakthrough for its further development.
