In recent years, farming of marine species has increased with higher protein and lower lipid demands. The main feed ingredients, have been fish meal and oil. But predictions suggest shortage in oils within a few years, and in proteins within a decade, so alternative feed resources are required. Vegetable products can be used, but most protein sources contain unvanted compounds like antinutritional factors and sterols, and vegetable lipid will alter depot lipids from a marine ""healthy"" PUFA composition to a ""vegetable"" like composition. This may jeopardize the competitiveness of aquaculture products as health benefit for human consumption. In order to produce fish with high marine PUFA profiles without antinutiritional factors, new marine feed resources are needed. The only significant biomass is found at lower trophic levels. But the knowledge on their suitability as fish feeds are at present very limited, and a major effort is required in order to obtaine reliable data.
The current initiative we will create a multidisciplinary platform containing national and international institutions having dedicated activities into this field. The group will contain expertise in biochemistry, microbiology, histology, analytical chemistry (environmental toxins, fluoride), and will cover science areas from catch conservation, process technology, feed production, fish growth, behavior, welfare and health.
Performance target:
To investigate and characterize the suitability of feed resources from lower trophic levels as feed for farmed fish.
Sub-goals:
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 variation and content in the raw material of heavy metals and pollutants (dioxins, PCBs).
3. To examine the effect of different raw material processing on the composition and the quality of the product.
4. To investigate the effect of oil and flour products on the growth, welfare and feed turnover of salmon, cod and halibut.
5. To investigate the effect of chitin on growth and welfare.
6. To investigate absorption and deposition of fluoride from chitin in fish."
