“…Therefore, it is expected that the pattern of spatial distribution of organisms is, to a great extent, driven by the contaminant. intermittent displacements to previously avoided fish farming effluent concentrations were observed when food was provided (Ara ujo et al 2016d). For instance, a higher abundance of fish larvae from different species was observed in the most disturbed and contaminated areas of the estuarine zones of New South Wales (Australia), probably attributable to nutrient enrichment (McKinley et al 2011).…”

Bioassays using the nonforced exposure approach have been shown to be a relevant tool that might complement the traditional ecotoxicological risk assessment. Because the nonforced exposure approach is based on spatial displacement of organisms and the consequent habitat selection processes, the population density might play an important role in the decision to avoid or prefer an ecosystem. Therefore, the aim of the present study was to assess if the avoidance response to contamination, measured in a nonforced exposure system, is density‐dependent and how determinant contamination could be for the habitat‐selection process in comparison with the population density. The freshwater shrimp Atyaephyra desmarestii was exposed to a copper gradient in a nonforced exposure system formed by 7 interconnected compartments (total volume 600 mL), which contained different copper concentrations. The density treatments used were 3, 5, and 10 organisms per compartment, corresponding to 0.5, 0.8, and 1.7 organisms per 100 mL, respectively. Clearly, the avoidance response to copper was more intense in the population with the lower density: the highest population density showed the lowest avoidance. The concentrations that triggered an avoidance of 50% of the population were 47, 134, and 163 μg L−1. In summary, it was observed that shrimps were able to detect and avoid potentially toxic copper concentrations but that the avoidance response was affected by population density.

“…In a study with tilapia fry (Oreochromis sp.) intermittent displacements to previously avoided fish farming effluent concentrations were observed when food was provided (Ara ujo et al 2016d). These controversial data have raised different questions about how determinant contaminants are for an organism's habitat-selection processes.…”

“…Several studies have been using the non-forced exposure system, and fish responses are similar to those described in this paper, such as D. rerio , Rachycentron canadum (Araújo et al, 2015) and Oreochromis sp. (Araújo et al, 2016). This system has also been applied in other researches, with distinct organisms, showing the ability of bionicators to detect stressors and move to less contaminated areas: amphibians (Vasconcelos et al, 2016) and invertebrates Araújo et al, 2016).…”

“…Therefore, the use of toxicity tests involving the long-term exposure of organisms under confined conditions, with no possibility of escape, could be considered unrepresentative of real exposure scenarios. In order to achieve better simulation of real contamination scenarios, where a contamination gradient is expected, a non-forced exposure system should preferably be employed Araújo et al, 2014Araújo et al, , 2016. This new approach using a non-forced exposure system has been used in ecotoxicology as a complementary tool to analyze the ways that contaminants can affect the spatial distributions of organisms .…”
