Abstract
Fatty acids are important parameters of egg quality in teleost species. The n-3/n-6 polyunsaturated fatty acid ratio in the natural diet of all limnic organisms differs between fresh and marine environment, being much lower in fresh-water compared to marine water. In the development of Arctic charr farming, the feed used in other salmonid species, mostly rainbow trout, is assume to be suitable. It has been discussed that Arctic charr fatty acid requirements differ from other salmonid species, caused by different abilities of desaturation and elongation of fatty acids. The quality difference and hatching results comparisons between wild and farmed broodstock fish gametes support this idea. Therefore we have analysed the fatty acids and aim to develop a suitable broodstock feed with an evolutionary well balanced fatty acid composition
