Abstract
Rainbow trout (Salmo gairdnerii) under light anaesthesia with MS 222 (tricaine methanesulphonate) died when their blood pH was lowered into the range of 6.8 to 6.9 by injection of either lactic acid or hydrochloric acid. When injection of the same quantities of either acid did not lower the blood pH into this range, fatalities did not result (one exception in 56 fish injected). The injection of much larger quantities of lactate or chloride ions in the form of sodium salts did not cause fatalities.Very limited data for sockeye salmon (Oncorhynchus nerka) suggest a similar association between blood pH and mortality for this species.This publication has 6 references indexed in Scilit:
