Research efforts have centered on behavioral pathology resulting from microchemical toxication of fishes, the quantification of which has proved to be an analytical tool of great sensitivity. For example, behavioral aberrations have been recorded in goldfish exposed to Toxaphene at 0.44 micro gm/1 or 25 times greater than that producing behavior aberrations. The various experimental results presented for 264 hours. The 96 hour TL(m) under the same experimental conditions was 11.0 micro gm/1 or 25 times greater than that producing behavior aberrations. The various experimental results presented herein are believed to demonstrate some of the potential of this approach in quantifying the effects of sublethal concentrations of water contaminants.
