The use of the ethanol pathway in goldfish Carassius auratus (L.) following anoxia
Goldfish (Carassius auratus) were subjected, for a period of 6 weeks, to 2h progressive hypoxia followed by 6h anoxia in closed respirometers at 15 degree C. The concentrations of glucose, lactate and ethanol were determined in whole goldfish following exposure to both hypoxia and anoxia. Lactate accumulation (mmol/kg/h) was 0.35 during the 1st week but declined to 0.14 in the 6th week of exposure to anoxia. In contrast, ethanol excreted to the surrounding water, increased from 65% to 92% of the total production in the lst and 6th week, respectively. The switch from lactate accumulation to ethanol pathway utilization, with the resultant metabolic depression and anoxia resistance is discussed
