The fatty acid (FA) composition in the heart tissue and white muscle of 13 species/ecoforms of Lake Baikal fish was determined. All the FAs usually found in freshwater or marine fish were detected in both tissues of all species studied. White muscle

The predator–prey relationship with respect to fatty acids (FAs) was studied in 57 harp seals Pagophilus groenlandicus and 16 potential prey species collected simultaneously in the northwestern Barents Sea in May–June 2006. The FA composition of

The fatty-acid composition of tissues from Lake Baikal hydrobionts involved in the food chain such as Baikal seals, fish, and amphipods was studied. GC–MS detected more than 40 fatty acids with different degrees of unsaturation in tissues of Baikal

Adductor muscle fatty acid (FA) composition was compared in Pecten maximus juveniles originating from five locations along the Norwegian coast from 59°N to 65°N to detect possible population differences. Broodstock sized scallops were translocated

This study represents the first determination of lipids and fatty acids in fish scales. Scales collected from groups of Atlantic salmon reared on fish farms and in experimental tanks were analyzed by chromatography. The complete suite of fatty acids

The variation of fatty acid (FA) content and composition of the microalgal production (Isochrysis sp., Pavlova lutheri and Chaetoceros muelleri) in a continuous large-scale production system (500-L bags) used in hatcheries were analysed. The variatio

Blubber biopsies were collected from 18 adult male walruses from Svalbard, Norway. The biopsies were taken vertically through the skin and the entire blubber layer down to, but not including, the muscle layer. Fatty acid (FA) compositions of inner bl

Multivariate analyses of fatty acid composition of Astarte sulcata, collected in Northwest Norway in October 2005, showed significant differences between geographically close populations. This biochemical heterogeneity may have been caused by high ge

This study of vertical fatty acid profiles, based on analysis of 58 fatty acids sampled at 3-mm intervals throughout the blubber column of a model marine mammal, the ringed seal (Pusa hispida), revealed three chemically distinct layers. The average d
