title: Estimation of acute toxicity of ammonium sulphate to the fresh water catfish, Heteropneustes fossilis I. Analysis of LC50 values determined by various methods.
abstract: The acute toxic effects of ammonium sulphate to fresh-water catfish, Heteropneustes fossilis (H. fossilis) have been studied by determining LC50 values with 95% confidence limits, by the graphic method, the logistic method, the Spearman and Karber method and the trimmed Spearman-Karber method. The trimmed Spearman-Karber method was found the most ideal for ammonium salt toxicity test. The flaws in the trimmed Spearman-Karber method are also discussed.
