The contents of total lipids and lipid fractions, the intensity of oxidative processes, and the antioxidant defense level in the blood, kidney, spleen, and liver of the Antarctic toothfish Dissostichus mawsoni (Actinopterygii: Nototheniidae) that inhabit stably cold Antarctic waters were studied depending on gender and age. This study revealed no significant differences between males and females. Significant variations in some parameters between the age groups of toothfish were found in the blood and liver. However, the differences in most of the studied parameters were insignificant, which is probably due to the capture of fish during their feeding period. The high content of total lipids, the content of stored triacylglycerols, and the antioxidant defense level in the blood and organs of D. mawsoni reflect the physiological features that make it possible for the species to live in Antarctic conditions.
