This type of behavior makes up the vast majority of behavior we expect to see with our fish then one day spawning season hits and our fish are at each others throats, or at least chasing each others tails. To assess how the presence and subsequent uptake of dissolved oxazepam may affect fish behavior, we exposed naturally spawned juvenile perch to water with two different concentrations of oxazepam: a low, environmentally relevant concentration of 18 μg liter −1 and a high concentration of 910 μg liter −1.
