Ventilation frequency ( F V ) in motionless common sole Solea solea was measured before and after a startling stimulus in normoxia and in hypoxia (15% air saturation). Startling reduced F V in normoxia (from mean ± s.e. 41 ± 3·3 beats min −1 to near zero, i.e . 2·0 ± 1·8 beats min −1 ) and in hypoxia (from mean ± s.e. 80 ± 4·4 to 58·8 ± 12·9 beats min −1 ). It is suggested that the maintenance of high F V in hypoxia may increase the probability of detection by predators compared to normoxia.
