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 in protein (39.1% d.m.), while macroalgae presented an association of high moisture (89% of wet matter), high minerals (36.5% d.m.), low lipids (1.8% d.m.) and very low protein (17.5% d.m.). The poor nutritional value of these food items seems to be compensated for by high food intake. Sulfur levels in fish tissues were negatively related to fish size. Sulfur and nitrogen were inter-correlated strongly and positively, and most of the sulfate is probably derived in muscle and liver from sulfur-containing amino acids.

Notothenioid fish of 3 species - 23 immature Notothenia coriiceps, 4 Gobionotothen gibberifrons and 11 Chaenocephalus aceratus, from the coastal zone at the South Orkney Islands were examined to determine their parasite infection. Five digenean species from the intestine, one monogenean species from the skin, two tetraphyllidean larval forms (cercoids) from the intestine, and diphyllobothriid plerocercoids from the stomach’s wall, liver and body cavity are reported. Infections are compared with those of fish from adjacent island groups along the Scotia Arc. Parasite infections of the fish from the South Orkney Islands were more similar to those at the South Shetland Islands area than at South Georgia. The infection of N. coriiceps and G. gibberifrons is similar to that of fjord fish at South Georgia and the South Shetland Islands, whereas the parasite burden of Ch. aceratus was more similar to that of this fish species inhabiting the open sea.
