Na + /H + and Cl -/HCO 3 -exchanges in the branchial epithelium are thought to be primarily responsible for acid-base transfers in fish. Several different cellular mechanisms have been proposed to drive these exchanges in fresh water and marine species. We measured the acidbase balance and net H + t

Varying the concentration of un-ionized ammonia (NH,) in the medium perfusing the gills of the isolated fish head while holding the total ammonia (NH,' + NH,) concentration constant had no significant effect on gill ammonia excretion. In contrast, alteration in the medium NH,+ concentration at a fix
The transepithelial potential (TEP) across the gills of a seawater teleost, the long-horned sculpin (Myoxocephalus octodecimspinosus), was measured both in vivo and utilizing a n isolated, perfused head preparation (IPHP). The TEP of the IPHP was compared to that of the whole animal while in normal
