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.
通过使用图形法、逻辑法、Spearman 和 Karber 法以及修正的 Spearman-Karber 法测定半数致死浓度（LC50）值及 95%置信限，研究了硫酸铵对淡水鲶鱼（Heteropneustes fossilis，简称 H. fossilis）的急性毒性作用。结果发现修正的 Spearman-Karber 法是铵盐毒性试验最理想的方法。文中还讨论了修正的 Spearman-Karber 法存在的缺陷。
