Abstract

Anesthesia handling and activity can produce large variations in some of the parameters of circulation and breathing movements in fish Handling and MS222 anesthesis cause a large increase in heart rate in the tench but have the reverse effect on the trout Hypoxia causes a decreased heart rate and changes in dorsal aortic blood pressure Serial sampling of the blood appears to have little effect on the parameters of circulation if the blood is replaced with saline Removal of blood without replacement causes a decrease in blood pressure and a slowing of the heart It is suggested that much of the variability observed in the measurement of circulatory parameters in fish can be accounted for by the experimental procedure rather than demonstrating large interspecific variations in teleost fish
