摘要: Abstract 1. Heart rate, ventilation rate and routine oxygen consumption were measured in Salmo gairdneri, Lepomis macrochirus Ictalurus nebulosus during rapid hypoxic stress recovery under normoxic conditions. 2. Cardiac respiratory responses hypoxia similar to those reported the literature for teleost fish. 3. Immediate increases heart occurred all three species after stress. When mean each at 1 hr post-stress was compared with its pre-stress differences patterns found species. 4. During from hypoxia, above levels S. gairdneri L. macrochirus. No significant between values I. nebulosus.
