Current models of branchial acidbase excretion in freshwater rainbow trout propose two main ionocyte types...

...D. J. Randall; T. K. N. Tsui SUMMARY The gills are the major site of acidbase regulation in most fish. Acidbase transfer across fish gills is dominated by carbon dioxide and ammonia excretion, especially the former. Bicarbonate buffering in the blood is less than that found in mammals; regulation...

.... A low urine pH is needed to achieve high rates of excretion of NH 4 + . Hence the price to pay to defend acidbase balance would be to accept a risk of precipitation of uric acid in the terminal nephron. This led us to reconsider the traditional view of the physiology of the excretion of NH 4...
