... toadfish modulate both the expression of Rh isoforms and urea synthesis pathways to tightly control and regulate nitrogen excretion. The results of the present study implicate Rh proteins in the unusual nitrogen excretion patterns of the gulf toadfish. Branchial Rh expression was low in crowded...

...Tammy M. Rodela; Patricia A. Wright SUMMARY An unusual characteristic of nitrogen excretion in the ammoniotelic mangrove killifish Rivulus marmoratus is that urea is excreted( J urea ) in a distinct diurnal pattern, whereas ammonia is excreted ( J amm ) at a steady rate. In this study we tested the...

...Makiko Kajimura; Sara J. Croke; Chris N. Glover; Chris M. Wood SUMMARY Ammonia and urea are the primary forms of nitrogen excretion in teleost fish. There exists, however, a discrepancy between the sum of ammonia plus urea nitrogen and total nitrogen, indicating that `unknown' nitrogen end products...
