T h e fish has no immediate appreciation of the low oxygen concentration and generally swims across the boundary without any hesitation. Occasionally it will make a sudden, jerky respiratory movement but swims on. m. m. shows five such traverses at 8-10 min. m. at 5 min and 14 min). Sooner or later this random movement takes the animal across the boundary into the well-aerated water when the stimulus to swimming seems to disappear. Usually this happens with the greatest abruptness so that the fish only swims about 10 cm into the wellaerated water and then becomes motionless for a minute or two while its respiratory movements return to normal.
