The effects of cyclic and constant hydrostatic pressure on the norepinephrine and epinephrine content in discrete regions of the brain of European flounder Platichthys flesus were studied. After a 14 day exposure to cyclic hydrostatic pressure with a tidal period of 12·4 h and with a maximum peak of 800 kPa (range 200–800 kPa of absolute hydrostatic pressure), fish showed a highly significant decrease in norepinephrine content when compared to control animals held at constant atmospheric pressure. No changes were detected in fish submitted to a constant hydrostatic pressure of 800 kPa.
