August Krogh proposed that freshwater fishes (and other freshwater animals) maintain body
NaCl homoeostasis by extracting these ions from the environment via separate Na+/NH4+ …

Recent studies have demonstrated that the transport mechanisms for Na+ and Cl− uptake
across freshwater fish gills (ie Na+/H+, Na+/NH4+ and C1−/HCO3− exchange systems) also …

Ammonia theoretically can traverse the gill epithelium of aquatic animals in a variety of
ways. Recent experiments utilizing both whole animals (fish and arthropods), and perfused …

The mechanisms of ammonia excretion at fish gills have been studied for decades but
details remain unclear, with continuing debate on the relative importance of non-ionic NH3 …

We have explored the molecular basis for differences in physiological function between the
gills and opercular epithelium of the euryhaline killifish Fundulus heteroclitus. These tissues …

The secondary active Cl− secretion in seawater (SW) teleost fish gills and elasmobranch
rectal gland involves basolateral Na+, K+‐ATPase and NKCC, apical membrane CFTR …

Much of the early research elucidating the general mechanisms of euryhalinity was
performed on the common killifish. More recently, its opercular epithelium with abundant …

Biochemical procedures developed to isolate plasma membranes from the branchial
epithelium of rainbow trout (Oncorhynchus mykiss) yield membrane fractions that are …

1. The evidence for the current model for ionic exchange mechanisms across the outer
surface of the fresh water acclimated fish gill is reviewed. 2. 2. It is suggested that recent …
