Batches of fifteen fishes were exposed to four different concentrations of the fungicides. Concentrations given are the final concentrations (v/v) in the aquarium water containing de-chlorinated tap water. Values given in parenthesis are lower and upper confidence limits of LC value. Negative correlation coefficient is found between the product moment of LC values and exposure periods
