The acute toxicity of alkylbenzene sulphonate (ABS) detergent to the toothed carp, Aphyosemion gairdneri (L.), was investigated using static bioassays and continuous aeration over a period of 96 h. The 96‐h LC 50 , opercular ventilation rates per minute and behaviourial responses were evaluated. The 96‐h LC was determined to be 25.11 ± 8.4 mg l −1 . The toxicant led to an initial increase in the opercular ventilation, which then decreased below the initial values by the 96th hour of exposure. Prior to death, erratic swimming, lost of balance and respiratory distress were observed. Skin lesions and haemorrhaging of the gill filaments were observed on dead fish.
