Eighty turbot, Scophthalmus maximus (L.), (average weight 61 g) were injected intraperitoneally with exactly 1 g glucose per kg body weight. There was a peak in plasma glucose 3 h post injection. Thereafter a gradual decrease to basal levels was seen within 24 h. Plasma triacylglycerol concentrations showed a rapid decline during the first 24 h, and thereafter stable values. Blood haematocrit values decreased from 20% before injection to 16% 72 h after injection. Liver glycogen concentrations showed an initial decrease from 8 to 5 g/100 g (w.w) during the first 12 h, and thereafter stable values, while muscle glycogen concentrations increased during the first 12 h, and thereafter showed a gradual decline until 72 h. This response was most probably caused by secondary changes upon handling in combination with the direct response to a glucose load. Thus turbot was able to restore alterations in carbohydrate metabolism efficiently within 24 h
