Zebrafish are an extremely important model species in biology due to their similar genome and evolutionary history with humans. Zebrafish often are kept in conditions causing chronic stress, and this brings about physiological consequences. However, there is almost no research on the impact of such stress on neuronal development. Using their alarm pheromone and an olfactory blocker, we were able to control the stress level of captive zebrafish and show the possible effects of chronic stress on zebrafish neural development. These results could call for a major re-evaluation of all neural and developmental zebrafish research to date and redefine the routine handling and care for one of the model vertebrate research species.
