teleost fish osmoregulation

See text for details. In the 1930s, two pioneers in fish osmoregulation (Homer Smith and Ancel Keys) demonstrated that teleosts ingest SW to offset the osmotic loss of water and excrete the excess NaCl, using the gills, rather than the kidneys (as mammals and birds do). 3, Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, Vol. Hideya Takahashi, Tatsuya Sakamoto. In reviewing the evidence prior to 1969, Chester Jones et al. Fish osmoregulation has always attracted considerable attention and in the last years several studies have increased our knowledge of this physiological process. 48, No. Funkenstein, B., R. Almuly, and S. J. Chan. Somewhat surprisingly, the V-type H+-ATPase appeared to be localized to the basolateral membrane in the killifish. The European flounder spends most of its life in the sea but often migrates into estuaries and rivers. 4, 1 April 2009 | American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, Vol. 13Bill Potts and Len Kirschner were pioneers in comparative animal osmoregulation. Most of the regulatory actions described above have examined seawater-adapted fish, and there is relatively little information on rapid stimulation of transport epithelia involved in net ion uptake in fresh water (Marshall, 1995). Although a broad generalization that holds for all teleosts is unlikely, our current understanding indicates that growth hormone promotes acclimation to seawater, prolactin promotes acclimation to fresh water, and cortisol interacts with both of these hormones thus having a dual osmoregulatory function. It should be noted that only a small number of teleosts have been examined and that we know little or nothing about the hormonal control of osmoregulation in the vast majority of fish. Tipsmark and Madsen (2001) have recently shown that elevated gill cAMP levels are associated with inhibition of Na+, K+-ATPase in brown trout, though the neuroendocrine signal for this response has yet to be elucidated. It is generally assumed that basolateral Na+-K+-activated ATPase provides the pathway for basolateral transport of Na+ into the extracellular fluids, but there is some evidence that a basolateral Na++ HCO3− cotransporter may also be involved in the rainbow trout (102, 107) and Osorezan dace (52). Conversely, low growth hormone and high prolactin will cause cortisol to promote ion uptake. 2, 1 October 2009 | American Journal of Physiology-Cell Physiology, Vol. In summary, modern, molecular techniques have provided an array of data that have extended and clarified the models of gill salt transport that were first proposed by Krogh, Smith, and Keys. DOI link for Fish Osmoregulation. Sodium may enter the gill epithelia by exchange with H+, or through an apical Na+ channel coupled to an apical H+-ATPase, and then leave at the basolateral surface through Na+, K+ATPase. 61). Teleost Osmoregulation Peter H.M. Klaren, Edwin J.W. Epinephrine, neuropeptide Y and somatostatin have been shown to decrease NaCl and water absorption across the isolated intestine of seawater-adapted Japanese eel (Anguilla japonica) and goby (Gillichthys mirabilis) (Ando and Hara, 1994; Uesaka et al., 1994, 1996; Loretz, 1995). Although there is substantial evidence indicating that cortisol can increase gill and gut Na+, K+ATPase, it is unclear whether this is primarily related to cortisol's seawater-adaptive effects, or whether upregulation of the sodium pump is also involved in ion uptake.
