AB  - Carbohydrate metabolism and the antioxidant defence system of heart and muscle of 
      the Antarctic notothenioids Notothenia rossii and Notothenia coriiceps were 
      evaluated in response to heat stress (8  degrees C) over 144 h. N. rossii heart exhibited 
      decreased glycolysis and aerobic metabolism after up to 12 h of exposure to 8  degrees C, 
      and anaerobiosis was inhibited within 24 h. However, these pathways were 
      stimulated after 72 h at 8  degrees C. The consumption of glucose-6-phosphate, derived 
      from hexokinase (HK), by glucose-6-phosphate dehydrogenase (G6PDH) decreased in 
      N. rossii heart within 6 h at 8  degrees C, with a subsequent increase at 72 h. In 
      N. rossii muscle at 8  degrees C, glycolysis was stimulated within 2 h by an increase in 
      pyruvate kinase (PK), and aerobic metabolism was stimulated at 144 h, together 
      with anaerobiosis. In N. coriiceps heart at 8  degrees C, glucose break down by HK 
      decreased within 2 h and subsequently increased at 12 and 24 h. Increased 
      glucose-6-phosphate consumption by G6PDH occurred within 6 h at 8  degrees C. In 
      N. coriiceps muscle at 8  degrees C, glycolysis was stimulated at 2 and 6 h, with 
      subsequent inhibition within 24 h, as indicated by HK activity. Aerobic 
      metabolism was inhibited at 72 and 144 h at 8  degrees C through the inhibition of 
      citrate synthase (CS). Heat stress caused responses were only occasional and 
      transient in antioxidant defence system of both species in the heart and muscle, 
      leading to increased glutathione (GSH) and decreased levels of lipoperoxidation 
      in the heart of both species. The results obtained in this study in the heart and 
      muscles indicate that under heat stress at 8  degrees C, N. rossii is more responsive 
      than N. coriiceps with respect to carbohydrate metabolism.
