The tolerance of seawater fish Japanese sea bass and black rockf ishto pH and alkalinity is studied through the experiment of acute toxicity. The median lethal concentration values are obtained by the method of probability unit. The safe concentrations of alkalinity, C032- and HC03- are obtained. The signification of pH and alkalinity is estimated with analysis of variance.
