Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon
Journal of Fish Biology, Volume 108, Issue 3, Page 881-893, March 2026.Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).
