“…In the last decade, several biosensor systems were developed using behavioral responses of aquatic organisms (fish, water-fleas, protozoans and mussels) for infield or laboratory biomonitoring (Charoy et al 1995;Wolf et al 1998;Häder 1999, 2001). Behavioral response biomonitoring are efficient for early warning responses to pollutants in aquatic systems and may be used for quality control of industrial treatment plants, to detect toxic waves, and to assess surface water quality for public supply.…”

“…Evaluation of swimming activity is useful to determine sublethal effects of chemicals in the laboratory or under controlled conditions in field. Detection of abnormal activity is based on comparisons of response of exposed fishes either with activity measured during baseline, pre-exposure period or observation of fishes under a control treatment (Ellgaard et al 1978;Thomas et al 1996;Wolf et al 1998;Kane et al 2004;Swain et al 2004).…”

We evaluated behavioral responses of zebrafish Danio rerio exposed to sublethal concentrations of sodium hypochlorite using an image analysis biomonitoring system (IABS). First, the limits of normal variation in swimming activity of zebrafish were determined by monitoring traveled distance of 40 control fishes using the IABS. An acute toxicity test was performed to determine the LC(50(24 h)) for D. rerio to NaOCl. To evaluate the toxic effects in swimming activity, 32 fishes were exposed to 40%, 30%, 20%, 10% of the LC(50 )and 32 were used as control using the IABS. We considered toxic concentrations where more than 10% intervals of the treated group were below the limits of normal variation and were significantly different from the control group. Two main responses were observed: an escape response (increased swimming activity) at 10% treated group, a gradual decrease in swimming activity from the 20% of the LC(50) on, and an avoidance response at higher concentrations. The response of the 20% treated group were considered as a NOAEL and responses of the 30% and 40% treated groups indicated significant hypoactivity (adverse effect). This behavioral biomonitoring system has proven to be a useful tool to detect sublethal toxicity that could be incorporated in biomonitoring protocols in Brazil.

“…In the 1980s systems were developed for detecting the movement of "sh or microorganisms (Yachaida et al, 1981;HaK der and Lebert, 1985). During the 1990s biological test systems in which digital image analysis was used in ecotoxicological risk assessment were developed (Steinberg et al, 1995;Wolf et al, 1998;Tahedl and HaK der, 1999). In these systems many moving organisms are identi"ed simultaneously in a series of consecutive frames, and the moving vectors (trajectories) are used to calculate movement parameters describing the velocity, shoal behavior, or orientation of the organisms.…”

Behavior is increasingly reported as a sensitive and early indicator of toxicant stress in aquatic organisms. However, the systematic understanding of behavioral effects and comparisons between effect profiles is hampered because the available studies are limited to few chemicals and differ in the exposure conditions and effect parameters examined. The aims of the present study were 1) to explore behavioral responses of Daphnia magna exposed to different toxicants, 2) to compare behavioral effect profiles with regard to chemical modes of action, and 3) to determine the sensitivity and response time of behavioral parameters in a new multi-cell exposure system named Multi-DaphTrack compared with currently utilized tests. Twelve compounds covering different modes of toxic action were selected to sample a wide range of potential effect profiles. Acute standard immobilization tests and 48 h of behavioral tracking were performed in the customized Multi-DaphTrack system and a single-cell commercialized biological early warning system. Contrasting behavioral profiles were observed for average speed (i.e., intensity, time of effect onset, effect duration), but no distinct behavioral profiles could be drawn from the chemical mode of action. Most compounds tested in the Multi-DaphTrack system induced an early and significant average speed increase at concentrations near or below the 10% effective concentration (48 h) of the acute immobilization test, demonstrating that the Multi-DaphTrack system is fast and sensitive. To conclude, behavior endpoints could be used as an alternative or complement to the current acute standard test or chemical analysis for the predictive evaluation of ecotoxic effects of effluents or water bodies.
