The multifunctional fish gill: dominant site of gas exchange, osmoregulation, acid-base regulation, and excretion of nitrogenous waste
The fish gill is a multipurpose organ that, in addition to providing for aquatic gas exchange,
plays dominant roles in osmotic and ionic regulation, acid-base regulation, and excretion of …

Ammonia production, excretion, toxicity, and defense in fish: a review
Many fishes are ammonotelic but some species can detoxify ammonia to glutamine or urea.
Certain fish species can accumulate high levels of ammonia in the brain or defense against …

Ammonia excretion and urea handling by fish gills: present understanding and future research challenges
MP Wilkie - Journal of experimental zoology, 2002 - Wiley Online Library
In fresh water fishes, ammonia is excreted across the branchial epithelium via passive NH3
diffusion. This NH3 is subsequently trapped as NH in an acidic unstirred boundary layer …
