摘要

A model of chronic predatory stress was effectively reproduced in Danio rerio. It was found that during chronic stress, the fish used an active coping strategy. The results of the novel tank diving test indicate the presence of anxiety and phobic disorders in stressed fish. Behavioral disorders are associated with an increase in serotonin levels with a simultaneous decrease in Z-MAO activity and a decrease in the level of cortisol in stressed fish.
