The toxicity of rotenone was determined for seven species of fish and three species of invertebrates. The results show that there is a marked variation in sensitivity of different species to rotenone. The survival times of roach Rutilus rutilus (L.) were reduced by a rise in temperature and also by a reduction in water hardness. Temperature affected the rate at which rotenone is degraded; 3 days after being prepared a solution containing 2 mg/1 of 5 % rotenone was non‐toxic to roach over a 7‐day period at 20°C, but it was still toxic for at least 11 days at 11.5°C. The data are discussed in relation to the use of rotenone in fisheries management.
