Discrimination between two reared stocks of cod ( Gadus morhua ) from the Faroe Islands by chemometry of the fatty acid composition in the heart tissue

Demersal fish assemblages of Faroe Bank: species composition, distribution, biomass spectrum and diversity

“…Tagging experiments with cod have demonstrated that migration between Faroe Bank and other areas is very low (Strubberg 1916, 1933, Tåning 1940, Joensen 1956, Jones 1966) and morphological as well as biochemical differences have been confirmed for cod on the bank (Love et al 1974). Growth rate of cod on Faroe Bank is higher than in most other areas (Ursin 1984, Fjallstein & Magnussen 1996 and genetic differences based on DNA (Dahle 1995) and fatty acids (Joensen et al 2000) have been demonstrated. For this reason the Faroe Bank cod stock is considered as a separate stock, which for all practical purposes does not mix with the nearby Faroe Plateau stock.…”

Fatty acid profiles in different fish species in Lake Baikal

“…The present study shows that the tissue FA profile can be used as a robust identifier, even at the ecoform level. This identification method has been successfully used on herring stocks (Grahl-Nielsen & Ulvund 1990), mackerel stocks (Grahl-Nielsen 2005), striped bass stocks (Grahl-Nielsen & Mjaavatten 1992), populations of cod (Joensen et al 2000), stocks of redfish (Joensen & Grahl-Nielsen 2004) and different strains of salmon (Grahl-Nielsen & Glover 2010).…”

Characterization of Phospholipid Molecular Species by Means of HPLC-Tandem Mass Spectrometry

“…wild/farmed) are the information which must be labelled in fishery and aquaculture products according to EU labelling regulations (Commission Regulation (EC) No 2065. TGs are considered as markers for wild and farmed fish since their profile reflects the diet lipids (Standal et al, 2010), whereas the phospholipid profile is less affected by the diet and can be related to other variables, such as the species and stock (Joensen et al, 2000).…”
