ASTM E1768-95(2013) [ Withdrawn ]

This guide covers information on methods to measure and interpret ventilatory behavioral responses of freshwater fish to contaminants.

Ventilatory responses of some fish species can be measured relatively easily and quickly, providing a useful tool for biomonitoring studies of wastewaters, pure chemicals, surface water, and ground water.

Given the technological constraints of electrical components, it is currently not feasible to monitor bioelectric signals, such as those elicited in ventilatory behavior, in saline (>2 ppt) or high conductivity (>3000 µhos/cm) water using the procedures discussed in this guide. Therefore, this guide is restricted to the testing of freshwater matrices. See more
