This study investigated the air-breathing behavior, oxygen consumption, and respiratory responses of the air-breathing (AB) armored catfish Pterygoplichthys anisitsi. The hematological parameters and oxygenbinding characteristics of whole blood and stripped hemoglobin and the intermediate metabolism of selected tissue in normoxia, different hypoxic conditions, and after air exposure were also examined. In normoxia, this species exhibited high activity at night and AB behavior (2–5 AB h-1). The exposure to acute severe hypoxia elicited the AB behavior (4 AB h-1) during the day. Under progressive hypoxia without access to the water surface, the fish were oxyregulators with a critical O2 tension, calculated as the inspired water O2 pressure, as 47 ± 2 mmHg. At water O2 tensions lower than 40 mmHg, the fish exhibited continuous apnea behavior. The blood exhibited high capacity for transporting O2, having a cathodic hemoglobin component with a high Hb–O2 affinity. Under severe hypoxia, the fish used anaerobic metabolism to maintain metabolic rate. Air exposure revealed physiological and biochemical traits similar to those observed under normoxic conditions.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-06-25T16:20:38Z No. of bitstreams: 1 222222222.pdf: 560167 bytes, checksum: 31c2a86a1569ff074072c6863005901c (MD5)Approved for entry into archive by Alda Lima da Silva(sivalda@ufba.br) on 2013-06-27T21:01:40Z (GMT) No. of bitstreams: 1 222222222.pdf: 560167 bytes, checksum: 31c2a86a1569ff074072c6863005901c (MD5)Made available in DSpace on 2013-06-27T21:01:40Z (GMT).
