Toxicity of Distillery Effluent to the Cyprinid Weed Fish Rasbora daniconius (Ham).
The toxicity of distillery wastes to the fish Rasbora daniconius was tested by bioassay. Ten concentrations ranging from 1.0 to 100% were employed. It was found that the fish were quite tolerant at the 1% concentration for about 24 hours of exposure and survived even up to 96 hours. Mortality was noticed in concentrations from 1.5% onwards. In the concentrations of 3.0% and above there was a heavy mortality beginning at 15 hours of exposure. From the chemistry of the medium studied it was found that the toxicity was inversely proportional to pH but directly proportional to conductivity and bicarbonate alkalinity of the medium.
