Acid and base loads infused into the dorsal aorta of the freshwater channel catfish (Ictalurus punctatus Rafinesque) were excreted by both gills and kidneys. The gills excreted 2-3 times as much as the kidneys. After a 2 mmol . kg-1 load of NaHCO3, the gills excreted 50% of the net OH- load in the first 5 h, while the kidneys excreted 18% in the first 6 h. After a 2 mmol . kg-1 load of NH4Cl, the gills excreted 32% of the load in 6 h, and 16% was excreted renally in 20 h. There was no evidence… CONTINUE READING
