ABSTRACT
The tolerance of the African lungfish, Protopterus annectens (Owen) to acid water was investigated under laboratory conditions. Healthy adult specimens of the African lungfish, Prolopterus annectens; mean length 38.3cm ± 2.4, and mean weight 294.3g ± 4.2 were subjected to acid waters of concentrations that ranged from pH 3.8 to pH 7.4. P. annectens tolerated acid water from neutral pH 7.4 down to a pH of 4.6. It is possible that P. annectens was able to maintain almost a constant level of blood p1-I in acid waters due to the possession of acidophyllic cells in the gills which actively secrete H from the blood into the water medium.
