Early embryonic ethanol exposure impairs shoaling and the dopaminergic and serotoninergic systems in adult zebrafish

► Short exposure to low levels of alcohol at embryonic stage impairs behavior in adult fish. ► Behavioral impairment found confirms previous results and suggests that abnormal shoaling behavior is induced. ► Behavioral abnormality is accompanied by reduced dopamine, DOPAC, serotonin and 5HIAA levels from whole brain extracts. ► Behavioral and neurochemical abnormalities are correlative only but open new lines of research for FAS model development.
