title: Proximate composition, fatty acid and lipid class composition of the muscle from deep-sea teleosts and elasmobranchs.
abstract: Proximate composition of muscle was determined for the following deep-sea fish species: roughhead grenadier (Macrourus berglax), mora/deep-sea cod (Mora moro), Portuguese dogfish (Centroscymnus coelolepis), black dogfish (Centroscyllium fabricii), leafscale gulper shark (Centrophorus squamosus), greater lantern shark (Etmopterus princeps), smalleyed rabbitfish/ghostshark (Hydrolagus affinis), birdbeak dogfish (Deania calcea) and two species of smooth head (Alepocephalus bairdii and Alepocephalus agassizii). The first eight species contained less than 1% fat in the muscle, while the last two contained 3.0% and 3.6% fat, respectively. Fatty acid and lipid class composition was determined for the first five fish species and showed that the dominant class of lipids was phospholipids. The lipids consisted mainly of polyunsaturated fatty acids (PUFA), and docosahexaenoic acid (DHA) was the dominant fatty acid. Roughhead grenadier and mora showed resemblance to cod (Gadus morhua) regarding protein content, fat content and fatty acid composition. However, the muscle from the deep-sea fish species did contain a higher proportion of arachidonic acid (20:4n-6) than cod muscle.
