Fish quality
Farming of salmonids is at present a small but successful business in Sweden and is expected to increase considerably within the next years by export of both fingerlings, fertilised eggs and charr as food product. The fish, being an extreme cold water species, are mainly farmed in netpens located in the extremely nutrient poor waters in Northern and central Sweden. The research aims are: Aquaculture related research such as developing and testing new and sustainable ingredients in feed for farmed fish and to investigate the eating quality of the produced farmed fish.
The fatty acid composition of commercial diets based on marine fish oils does not reflect the fatty acid composition occurring in the food chain of wild Arctic charr. A serious obstacle in the farming of carnivorous fishes is related to the depleting resources of fish meal and fish oil which traditionally have been the main sources in the diet for farmed predatory fishes. By developing a feed based on a significant substitution of fish oil and fish meal with alternative ingredients Arctic charr can become a sustainable farmed product in Sweden.
