Abstract
Oxygen consumption, ammonia excretion and ammonia quotient (AQ) (vol. NH3/vol.O2) in the catfish,Mystus armatus, acclimated to and tested in fresh water at 30°C, were obtained with special reference to swimming speed and ambient oxygen. At normoxia the fish maintained an AQ of about 0·12, while at low ambient oxygen (below 2 ppm) the AQ increased sharply to a value of 0·3 indicating an increase in protein metabolism of hypoxic conditions.Mystus armatus exercising continuously for 5 hr at various swimming speeds, utilized more proteins during the later phase of exercise. The increased protein utilization may be of advantage in maintaining acid-base balance and also in conserving sodium (Na+) in fish.
In the recovery metabolism ofMystus armatus after hypoxic asphyxiation, the oxygen consumption showed a clearcut rise over the prehypoxic level, indicating that an oxygen debt was accumulating inMystus armatus exposed to hypoxia.
