Abstract


Bioassay experiment were carried out to determine the acute toxicity of sodium arsenate to a freshwater catfish, H. fossilis. The estimated value of 24, 48, 72 and 96h LC50 were 67.06, 49.52, 36.24 and 26.36 mgL-1 respectively; The presumably (safe) harmless concentrations of toxicants to this fish was 8.10 mgL-1. Heteropneustes fossilis exhibited behaviouoral responses such as hyperexitability, restlessness and erratic swimming movements on exposure to toxicant sodium arsenate but these symptom is more prominent at 96h exposure.
