“…This alteration in synchronization to external rhythms was a symptom of the seriously disturbed behavioral adjustment of Leucaspius delineatus. Similar changes in the circadian activity of rainbow trout exposed to copper were shown by Steele (1989) and Campbell et al (2002). In previous studies an MC-LR concentration of 50 g L Ϫ1 led to a phase shift of the activity of Danio rerio that coincided with reduced spawning activity and reduced spawning success (Baganz et al, 1998).…”

The spontaneous locomotor behavior separated into day/night activity phases of two fish species Danio rerio and Leucaspius delineatus was recorded and quantified continuously under sublethal long-term exposure to microcystin-LR in tanks. Microcystin-LR was applied in concentrations of 0.5, 5, 15, and 50 microg L(-1). By using an automated video-monitoring and object-tracing system, the average motility (swimming velocity) and the average number of turns were assessed. Clear dose-dependent effects of microcystin-LR on the behavior of both test fish were measured. During the daytime, the motility of Danio rerio as well as Leucaspius delineatus increased significantly by exposure to the lowest concentrations, whereas higher concentrations led to significantly decreased motility. Influenced by microcystin-LR, the swimming time of Leucaspius delineatus reversed, going from a prominently diurnal activity to a nocturnal one; Danio rerio remained active during the daytime. Most of the relative changes in the behavioral patterns of Danio rerio and Leucaspius delineatus suggest these fish have comparable susceptibility to microcystin-LR and may indicate some adverse consequences for fish populations, for example, in connection with reproduction and predator-prey interactions.

“…This analytical approach has been used not only to demonstrate increased variability in the activity of animals following sublethal exposure to Pb [17, 18, this study] and other heavy metals (M.B. Levine et al, unpublished data), but also for demonstrating decreased variability in die1 activity patterns of fish following sublethal exposure to copper [19].…”

Green frog (Rana clurnitans) tadpoles were exposed to 0, 500, 750 and 1,000 pg Pb/L (as lead nitrate) for 6 d (144 h). Previous studies have shown that similar exposure to 750 or 1,000 pg Pb/L produces deficiencies in both acquisition and retention of Iearned responses in green frog tadpoles. We examined preference/avoidance responses and spontaneous locomotor activity of Pbexposed and control tadpoles to plumes of Pb-polluted water at each concentration in an octagonal fluviarium. Results indicated no significant preference or avoidance of Pb by either control or Pbexposed animals, and no significant effects on the amount of locomotor activity. However, there was significantly greater ( p < 0.05; folded Ftest) variability in locomotor activity for tadpoles exposed to 750 and 1,OOO pg Pb/L compared to control animals and to those exposed to 500 pg Pb/L.

Previous studies have shown that similar exposure to 750 or 1,000 μg Pb/L produces deficiencies in both acquisition and retention of learned responses in green frog tadpoles. We examined preference/avoidance responses and spontaneous locomotor activity of Pb‐exposed and control tadpoles to plumes of Pb‐polluted water at each concentration in an octagonal fluviarium. Results indicated no significant preference or avoidance of Pb by either control or Pb‐exposed animals, and no significant effects on the amount of locomotor activity. However, there was significantly greater (p < 0.05; folded Ftest) variability in locomotor activity for tadpoles exposed to 750 and 1,000 μg Pb/L compared to control animals and to those exposed to 500 μg Pb/L.
