Oxygen requirements of whitefish and vendace (Coregoninae) embryos at final stages of their development

Whole eggs and excised embryos of vendace ( Coregonus albula) and whitefish ( C. lavaretus) were exposed to various partial pressures of oxygen for 60 min at 4 and 8 °C, and their heart rate was measured. Embryos responded to hypoxic conditions by a decrease in heart rate (bradycardia). The intensit...
