✦ Synopsis

Young of Tilapia nilotica L. were subjected to acidic and alkaline media of different pH over 24 h periods. Dilute hydrochloric acid was used to lower the hydrogen ion concentration of the test medium. A pH lower than 2.9 resulted in immediate mortality, whereas a pH of 3.5 and above produced no mortality. Alkaline media had no serious effect on survival.
