AbstractThis study examines the postprandial pH changes in the digestive tract of Cobia juveniles reared at 30° and 34° C. Cobia juveniles maintain a gastric luminal pH close to 4 throughout the day. A slight increase occurred after feeding due to the buffering and dilution effect of the ingested food and drinked sea water. In the intestine the luminal pH increased after the first meal and declines to neutral values by the end of the day. Higher alkalinization was observed in the intestine at 34° than at 30° C.
