Nest-defense behaviors in Fathead minnows after lifecycle exposure to the antidepressant venlafaxine
Venlafaxine is an antidepressant and anti-anxiety drug that has been detected in municipal wastewater at low micrograms per litre (ug\/L) concentrations. In this study, the nest-defense behavior of adult male fathead minnows (Pimephales promelas) was observed in fish exposed for a full lifecycle to venlafaxine nominal concentrations. Nest-defense behaviors quantified were the time taken to contact a dummy intruder fish (on a flexible stick, held near each nest) and the number of contacts made during a 1 minute period. This study is the first to assess reproductive behaviors in fish exposed to an antidepressant over a full lifecycle.
