Water quality encompasses the water physical, biological, and chemical parameters. It
generally affects the fish growth and welfare. Thus, the success of a commercial aquaculture …

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 …

Development and growth (continuous in fish) are controlled by 'internal factors' including
CNS, endocrinological and neuroendocrinological systems. Among vertebrates, they also …

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 …

The article discusses advances in osmoregulation and excretion with emphasis on how
multicellular animals in different osmotic environments regulate their milieu intérieur …

We identified five Na+/K+-ATPase α-isoforms in rainbow trout and characterized their
expression pattern in gills following seawater transfer. Three of these isoforms were closely …

The mechanisms of acute copper and silver toxicity in freshwater organisms appear similar.
Both result in inhibition of branchial sodium (and chloride) uptake initiating a cascade of …

Blood sampling through the caudal vasculature is a widely used technique in fish biology for
investigating organismal health and physiology. In live fishes, it can provide a quick, easy …

A strong foundation of basic and applied research documents that the estuarine fish
Fundulus heteroclitus and related species are unique laboratory and field models for …

Cystic fibrosis (CF) is caused by defects in an anion channel, the cystic fibrosis
transmembrane conductance regulator (CFTR). Recently, a new airway epithelial cell type …
