“…Lacroix and Townsend (1987) have shown that pH alone can be responsible for severe ionic imbalance, leading to mortality of the fish, and that ionic depletion was further enhanced by Al (in combination with low pH). Besides mortality, metals and acidity also produce numerous sublethal effects, such as feeding impairment and other behavioral alterations (Lacroix and Townsend, 1987;Blaxter and Hallers-Tjabbes, 1992;Peakall, 1992;Heath, 1995;Gerhardt, 1998;Beaumont et al, 2000). Biomarker alterations are also among the sublethal outcomes caused by metals.…”

The interest in the ecological relevance of risk assessments and, thus, in in situ bioassays has been increasing in the last years. The present study developed a time- and cost-effective in situ bioassay, aiming at obtaining, in a short period of time and with a minimum of resources, a set of ecologically relevant toxicological information in a site-specific approach. Poecilia reticulata and Gambusia holbrooki were chosen as test species. Post-exposure feeding inhibition and the biomarkers acetylcholinesterase, lactate dehydrogenase and glutathione S-transferases were the endpoints tested. The battery of biomarkers as a whole was sensitive to the in situ exposure in an acid mine drainage impacted effluent, although responses varied between test species. Post-exposure feeding inhibition was the most sensitive endpoint, and its association with biomarker responses was discussed. The linkage between individual responses, such as feeding, and biomarkers suggested that, at least in this case, biomarkers can be relevant at higher levels of biological organization. Altogether, the proposed short-term in situ bioassay seems to be a promising tool, since it represents a reasonable compromise between sensitivity, time/cost-effectiveness and ecological relevance.

“…The response of the effectors is then influenced with potential consequences on behavioral performance. In both fish and invertebrates, different sensory systems may be affected by contaminants such as light receptors, mechanoreceptors, chemoreceptors (Blaxter and Hallers-Tjabbes 1992;Scott and Sloman 2004). In aquatic biota, chemoreception is particularly important (Carreau and Pyle 2005).…”

Bridging the gap between early, sensitive responses to stress at the infra-organismal levels and long-term, ecologically relevant responses at the supra-organismal levels is a challenge. Behavioral ecotoxicology provides an approach that clearly links disturbances at the biochemical level (e .g., altered neurotransmitters and thyroid hormones) to effects at the population level. These effects may be direct, such as impairment of the search for a sexual partner, care of juveniles, and avoidance of predators or pollutants. Indirect effects may be alteration of reproduction success due to impairment of feeding and thus, energy metabolism. The sensitivity of behavioral responses can be useful in ecological risk assessment. A major difficulty is extrapolation of observed responses with test species to other species. Thus it is recommended to use behavioral biomarkers, associated with biochemical and physiological markers (neurotoxicity, hormones, energy metabolism) in carefully selected species. These sentinels must be key-species in the structure and functioning of ecosystems because impairments of their responses used as biomarkers will reveal a risk of cascading deleterious effects at the community and ecosystem levels.

“…Overall, this is a quite relevant scientific issue since most species of fish depends greatly on vision as a source of information. The vision mediates a large range of fish behaviours, from feeding to orientation and schooling [Blaxter and Hallers-Tjabbes, 1992]. Thus, functional disruption of fish eyes due to Hg accumulation could influence fish fitness and survival by reducing or changing the sensory information reaching the brain.…”
