Urea and Water Permeability in the Ureotelic Gulf Toadfish (Opsanus beta)
The permeability of toadfish gills and skin to urea and water has been measured in this species. A perfused gill preparation was used in the gil studies and isolated pieces of skin mounted in an Ussing chamber in the skin studies. Simultaneously, urea and water permeability was measured in vivo in free swimming fish. In vivo, the nonpulsing urea permeability was exceptionally low compared to other teleosts, while the tritiated water permeability was similar to that of other teleosts.
