“…In the case of dichlorvos exposure, behavior strength of D. magna changed with exposure time and concentrations. Higher concentrations (5 and 10 TU) resulted in a greater decrease in the behavior strength, and a shorter response time during the first phase behavioral response, which was regarded as avoidance behavior (Sager et al, 2000;Erik et al, 2005;Ren et al, 2009a). The behavioral responses of D. magna to the exposures of deltamethrin, cadmium chloride and dichlorvos were similar (Fig.…”

“…Motility is a characteristic feature of many organisms that cannot be neglected as an important physiological factor in survival (Putman and Wratten, 1984;Ren et al, 2009a). Behavioral responses in organisms associated with stress and toxicant exposure provide novel information including short term and median lethal exposure effects, and the potential for mortality (Andrew et al, 2004;Ren et al, 2007), which cannot be gained from traditional toxicological methods.…”

“…Behavioral responses in organisms associated with stress and toxicant exposure provide novel information including short term and median lethal exposure effects, and the potential for mortality (Andrew et al, 2004;Ren et al, 2007), which cannot be gained from traditional toxicological methods. Therefore, in the biological early warning of accidental water environment pollution, the on-line monitoring of the behavioral responses of aquatic organisms is viable (Ren et al, , 2009a(Ren et al, , 2009b.…”

“…The Japanese Madaka is an extensively studied species and has been proposed as the standard test fish in the OECD guidelines (OECD, 1999). Many data related to behavior in madaka have been reported (Gray et al, 1999;Oshima et al, 2003;Gormley and Teather, 2003;Chon et al, 2005;Ren et al, 2007Ren et al, , 2009aRen et al, , 2009b.…”

“…The results of DaphniaToximeter using D. magna suggested that the alarm rate of Daphnia-Toximeter could reach 100% in 2.5 mg/L Cd 2+ , and 50% in 0.5 mg/L Cd 2+ (Lechelt et al, 2000). The results of BEWs showed that the behavior strength of Japanese madaka could decrease to 0.2 in 10 min with 10 mg/L fenvalerate, and behavior strength of D. magna would decrease to zero within 3 hr with 50.0 μg/L malathion (Ren et al, 2008(Ren et al, , 2009a.…”

It is important to select suitable organisms to adapt the requirement of different environment monitoring purposes. Following our previous study, the behavioral responses of Daphnia magna and Japanese madaka (Oryzias latipes) were investigated and compared under flow-through conditions in an on-line biomonitoring system. The results showed that both D. magna and Japanese madaka had similar biological clock, but the circadian rhythms of Japanese madaka was more clearly recorded than that of D. magna. And the sensitivity of D. magna was about two orders of magnitudes higher than that of Japanese madaka in different types of toxic chemicals (dichlorovos, deltamethrin and cadmium chloride). However, when both animals were used in an on-line biomonitoring system, the life span of D. magna was less than 7 days and Japanese madaka could last for more than one month without feeding. Therefore, D. magna was proposed to be a more sensitive bioindicator and was suitable for short term monitoring the pollution events at concentration level closing to the water quality standard, while Japanese madaka was more suitable for the long-term monitoring for accidental discharges.

Most laboratory tests may underestimate adverse effects in real scenarios of contamination because they imply the forced exposure of organisms to contaminants, thus overlooking the possibility of emigration. Avoidance from contaminants has been observed in several aquatic organisms, and avoidance-based tests have been recommended to be included in risk assessment studies. To reduce uncertainty in the extrapolation of laboratory derived results, the first aim of the present study was to compare both the median avoidance concentration and the lowest-observed-effect gradient (LOEG) values of atrazine for the cladoceran Daphnia magna, between an already developed 1.1-m-long system and a scaled-up system, three times longer. Second, the present study aimed at evaluating the population immediate decline--the proportion of the population that disappears (avoids and, if not, dies)--through the integration of the relationships between lethality and avoidance versus contaminant concentration. Daphnia magna significantly avoided atrazine, during 12-h exposures, with similar results in the original and scaled-up systems. The population immediate decline at the 48-h median lethal concentration would be 94%. Even at a concentration eliciting only 5% mortality, the population immediate decline would be over 50%. Achieving a higher pertinence of avoidance results and a better understanding of the LOEG values and their time dependence, scaling up the system further both spatially and temporally, and modeling explicit spatial dynamics in exposure and organism movement in space and time are needed.

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.
