Laboratory and field experiments have been performed to evaluate a non-invasive biomonitoring system using the Asiatic clam Corbicula fluminea and Mulinia lateralis. C. fluminea was exposed to simulated episodic toxicity events in the laboratory using copper, diazinon, and regulated flow rates. Group behavior during these simulated events was compared to behavior during unstressed periods to develop a statistical model and an alarm criteria. Bayou Chico, Pensacola Bay, FL, was the site for field experiments in which M. lateralis was placed in situ to evaluate the performance of the biomonitoring system. The biomonitoring system consists of proximity sensors which detect an aluminum foil target attached to the valve of an organism. Valve movements of the clams are then digitally recorded using a personal computer. Data collected from remote sites are telemetered to the lab using short wave radio. In its final form, the authors envision an in situ biological monitoring system using bivalves deployed in aquatic systems in conjunction with automated monitoring systems like those found at USGS gauging stations. A tool such as this could be used as a warning system to increase the probability of detecting toxic events as they occur.
