Start year 2011 End year 2013 Funding (€) € 551,035 Website https://www.fhf.no/prosjekter/prosjektbasen/900764/ Summary An initial tax discovery project with Nofima as an R&D partner showed that deformed hearts in rainbow trout had a lower weight, higher fat content and a different fatty acid profile than normal hearts. With falling sea temperatures in the autumn of 2010, a statistically significant lower mortality (cause of death was arteriosclerosis / atherosclerosis in the heart) was observed in rainbow trout given experimental feed with a higher EPA / DHA (omega-3 fatty acid) level compared to the commercial control feed. The changes in the feed also resulted in increased growth, better feed utilization and higher harvest yields.
In connection with the low sea temperatures in Finnmark in winter, one therefore wants to continue the work of documenting whether the combination of high levels of vegetable raw materials (which has now become common in fish feed) and low sea temperatures on the site, increases the risk of heart disease, mortality and increased production costs in rainbow trout farming.
Documenting the extent to which high levels of rapeseed oil in the feed, in combination with low sea temperatures, increase the risk of heart disease, mortality and increased production costs in rainbow trout farming in Finnmark.
