Abstract
Rainbow trout, Salmo gairdneri, were exposed to gradual and rapid increases in pH to determine if they would acclimate to values above 9.0. The trout became acclimated to a pH of 9.8 when they were exposed to gradual increases over a period of 5 days. When trout were exposed to an increase of pH to 9.5 in 6 hours, marked stress and 50% mortality occurred. However, when the pH increase was to 9.3 in 6 hours, the trout only had a temporary loss of appetite.This publication has 3 references indexed in Scilit:
