The population structure of N. rossii (n = 221) was composed of juveniles, and that of N. coriiceps (n = 151) was composed of adults. The greatest mean length and weight measurements of N. coriiceps may be related to warming waters in the Antarctic Peninsula region. Salps were the dominant item in the diet of both species responsible for high protein quantity item found in muscle tissues and liver. The krill and amphipods were an important food item and related to lipid reserves. Among the indices evaluated, greater variation was observed in the hepatosomatic index of N. coriiceps and was related to the greater sizes and ages attained by this species. The liver and muscle energetic components showed great variability between different months may be related by the variability in diet. The plasma components did not exhibit seasonal patterns but displayed large monthly variation. Long-term analysis of the biological parameters evaluated in this study should be continued to monitor the species present in Admiralty Bay, a region with great biological diversity.
