Start year 2006 End year 2009 Funding (€) € 2,344,703 Website https://www.fhf.no/prosjekter/prosjektbasen/512042/ Summary The project has been funded through the Research Council of Norway with partial funding from FHF. The former has been responsible for ensuring the quality of the project professionally and administratively. The results clearly show that Atlantic salmon digest and utilize marine growth trees as an alternative source of fat. The conclusion from several studies is that wax is digested relatively poorly. But the fish compensates by increasing the production of emulsifiers (bile) and possibly also digestive lipases. This increase in digestive capacity was evident when fish that had previously been grown had diets with pure fish oil added. These fish had significantly increased digestive capacity compared to control groups who were constantly fed diets with fish oil.
"To investigate and characterize the suitability of feed resources from lower trophic levels as feed for farmed fish.
Sub-goal
1. To characterize the composition of relevant raw materials as a function of species, area and season. Focus on redfish ( Calanus finmarchicus ), amphipods ( Themisto libellula ), large krill ( Meganyctiphanes norvegica ) and small krill ( Thysanoessa inermis ).
2, To characterize the variation and content in the raw material of heavy metals and pollutants (dioxins, PCBs).
3, To investigate the effect of different raw material treatment on the composition and suffocation of the product.
4. To investigate the effect of oil and flour products on growth, welfare and feed turnover for salmon, cod and halibut.
5, To investigate the effect of chitin on growth and welfare.
6, To investigate the absorption and deposition of fluorine from chitin in fish."
