Abstract

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.

南极牙鱼 Dissostichus mawsoni Norman, 1937 (Nototheniidae) 血液和内脏器官中的脂质成分和氧化过程

摘要

研究了栖息在稳定寒冷的南极水域的南极齿鱼Dissostichus mawsoni（Actinopterygii：Nototheniidae）的血液、肾脏、脾脏和肝脏中总脂质和脂质组分的含量、氧化过程的强度和抗氧化防御水平。关于性别和年龄。这项研究表明，男性和女性之间没有显着差异。在血液和肝脏中发现不同年龄组牙鱼的某些参数存在显着差异。然而，大多数研究参数的差异并不显着，这可能是由于在喂食期间捕获了鱼类。总脂质含量高，储存的三酰甘油含量高，血液和器官中的抗氧化防御水平D. mawsoni反映了使该物种能够在南极条件下生活的生理特征。
