Teleost fishes are able to acclimatize to seawater by secreting excess NaCl by means of
specialized “ionocytes” in the gill epithelium. Antibodies against Na+/K+-ATPase (NKA) …

Freshwater fishes lose ions to the external medium owing to the steep concentration
gradients between the body fluids and the water. To maintain homeostasis, they use …

Fish encounter harsh ionic/osmotic gradients on their aquatic environments, and the
mechanisms through which they maintain internal homeostasis are more challenging …

Compared to terrestrial animals, fish have to cope with more-challenging osmotic and ionic
gradients from aquatic environments with diverse salinities, ion compositions, and pH …

Transepithelial transport is one of the major processes involved in the mechanism of
homeostasis of body fluids in vertebrates including fish. The current models of ion regulation …

Teleost fishes, living in fresh water, engage in active ion uptake to maintain ion homeostasis.
Current models for NaCl uptake involve Na+ uptake via an apical amiloride-sensitive …

A sufficient and timely energy supply is a prerequisite for the operation of iono-and
osmoregulatory mechanisms in fish. Measurements of whole-fish or isolated-gill (or other …

The Na+, K+-ATPase (the sodium pump) plays a crucial role in ion transport in the fish gill.
An immunocytochemical method has been optimized, using the mouse monoclonal antibody …

Publisher Summary This chapter discusses several ion regulatory mechanisms in freshwater
(FW) fish. In the mammalian kidney, different types of ion-transporting cells (ionocytes) in the …

Fish, like mammals, have to maintain their body fluid ionic and osmotic homeostasis through
sophisticated iono-/osmoregulation mechanisms, which are conducted mainly by ionocytes …
