Fig. 6. The effects of fasting/re-feeding on blood glucose and liver glycogen levels of Atlantic cod. (A) Blood glucose; (B) liver glycogen; (C) blood glucose versus liver glycogen from individual fish (y=0.29x+3.4; R²=0.20, P=0.017); fish were fed (N=10 for glucose; N=12 for glycogen) or deprived of food for 1 month (N=6) or 2 months (N=6). Starved fish were then re-fed (N=6) for 3 weeks. Columns with different letters are significantly different (P<0.05).
