Hyper-saline habitats (waters with salinity> 35 ppt) are among the harshest aquatic
environments. Relatively few species of teleost fish can tolerate salinities much above 50 …

We compared seawater tolerance, gill Na+/K+-ATPase and Na+/K+/2Cl–cotransporter
(NKCC) abundance, and mitochondria-rich cell (MRC) morphology of three salmonids, lake …

Mozambique tilapia Oreochromis mossambicus embryos were transferred from freshwater to
seawater and vice versa, and short-term changes in the localization of three major ion …

While the zebrafish is commonly used for studies of developmental biology and toxicology,
very little is known about their osmoregulatory physiology. The present investigation of Na+ …

The gill lamellar epithelium is composed of two predominant cell types, pavement cells and
mitochondria-rich chloride cells. The chloride cells play a vital role in ionic regulation …

We evaluate osmotic and chloride (Cl–) regulatory capability in the diadromous shrimp
Macrobrachium amazonicum, and the accompanying alterations in hemolymph osmolality …

This review examines the recent advances in our understanding of the mechanisms of ion
transport and acid-base regulation in the freshwater fish gill. The application of a …

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 …

The vulnerability of fish embryos and larvae to environmental factors is often attributed to a
lack of adult-like organ systems (gills) and thus insufficient homeostatic capacity. However …

We explored molecular and morphological alteration in gill mitochondria-rich (MR) cells of
Mozambique tilapia, Oreochromis mossambicus, acclimated to deionized freshwater (DFW) …
