A combination of low fat (6.1 and 4.8% of dry matter), high protein (78.6 and 84.3% d.m.) and mineral content (6.3 and 6.2% d.m.), as well as high moisture (80.8 and 81.7% of fresh matter), which is typical of Antarctic benthic fish, was found in the muscle of Notothenia coriiceps and Lepidonotothen nudifrons, respectively. Fish food items (whole amphipods) were high in minerals (34.3% d.m.) and poor...
