BioMed Central | Full text | Takifugu obscurusis a euryhaline fugu species very close to Takifugu rubripesand suitable ... To identify the molecular components involved in body fluid homeostasis, the change of expression of each gene during adaptation of euryhaline fishes to different salinities is a potential useful marker since the genes involved are expected to be drastically up- or down-regulated during the adaptation. In general, the largest difference between FW fish and glomerular SW fish regarding structure of the renal tubules is the presence or absence of a distal segment, which acts as a urine-diluting segment in FW fish [30]. Most of the euryhaline fish have a FW-fish type of nephron such as the European eel (Anguilla vulgaris), Pacific pink salmon (Oncorhynchus gorbuscha), rainbow trout (Oncorhynchus mykiss), southern flounder (Paralichthys lethostigma), armored sculpin (Leptocottus armatus), medaka (Oryzias latipes), and spotted green pufferfish [20,30]. www.biomedcentral.com /1472-6793/5/18   (5055 words)

Jonathan Z. Kaye 2004 6220 Four strains of euryhaline bacteria belonging to the genus Halomonas were tested for their response to a range of temperatures (2, 13, and 30°C), hydrostatic pressures (0.1, 7.5, 15, 25, 35, 45, and 55 MPa), and salinities (4, 11, and 17% total salts). An elevated salinity was previously shown to increase the maximum hydrostatic pressure for growth in the psychrophiles Moritella marina (54, 73) and Streptococcus faecalis (reclassified as Enterococcus faecalis [63]) (36) and to decrease the piezosensitivity of Escherichia coli to an extremely high hydrostatic pressure of 270 MPa (25). Consistent with previous studies of Halomonas strains and other moderately halophilic and euryhaline species (41, 42, 44, 51, 74, 77), the proportion of MUFA decreased in concentration (and the proportion of saturated fatty acids concomitantly increased in concentration) with increased salinity, as was observed with H. www.bionewsonline.com /f/d/jonathan_z_kaye_2004_6220.htm   (5484 words)

BioMed Central | Abstract | Takifugu obscurusis a euryhaline fugu species very close to Takifugu rubripesand suitable ... Takifugu obscurus is a euryhaline fugu species very close to Takifugu rubripes and suitable for studying osmoregulation Euryhaline fish that can survive both in freshwater (FW) and seawater (SW) are also very useful for studying fish physiology, especially osmoregulation. We have therefore determined its euryhalinity and phylogenetic relationship to the members of the Takifugu family. www.biomedcentral.com /1472-6793/5/18/abstract   (383 words)

Vasotocin-like activity in the plasms of the euryhaline frog (Rana cancrivora) after transfer from fresh water to ... When Rana cancrivora were collected from fresh water and dehydrated (weight loss 4-10%) by exposure to saline, the plasma titre of hydro-osmotic activity, measured by amphibian bladder assay, was increased three-to fourfold. Pituitary glands of hydrated and dehydrated frogs were estimated to have 0.15 and 0-18 mug vasotocin/gland respectively. The possible physiological function of released vasotocin in promoting reabsorption of urea from the urinary bladder is discussed in relation to the euryhaline ability of R. cancrivora. joe.endocrinology-journals.org /cgi/content/abstract/66/3/427   (233 words)

FERG Euryhaline teleost fish must integrate the functions of gill, gut and kidney in order to adapt successfully to the dramatically different environments they face as part of their natural life cycle. In seawater-adapted fish, the chloride cells are larger, and function principally to remove excess Na+ and Cl- ions. Gut: As euryhaline teleost fish adapt to seawater, they must compensate for the water lost across the gills. www.st-andrews.ac.uk /~ferg/Templates/TeleostA.htm   (708 words)

American Zoologist: Osmoregulation by gills of euryhaline crabs: Molecular analysis of transporters   (Site not responding. Last check: 2007-11-05) Although the crustacean intestine is known to transport ions (Mantel and Farmer, 1983) and appears to be the major site of water uptake at molt (Neufeld and Cameron, 1994), its overall contribution to osmoregulatory ion uptake is believed to be minimal (Chu, 1987). The majority of experimental evidence suggests that it is the gills of euryhaline crustaceans that serve as the primary site of osmoregulatory ion transport. Studies of intact animals, isolated gills, gill lamellae, and membrane vesicles have produced a variety of models of osmoregulatory ion transport in euryhaline crustaceans (Lucu, 1990; Towle, 1990; Taylor and Taylor, 1992; Pequeux, 1995; Onken and Riestenpatt, 1998). www.findarticles.com /p/articles/mi_qa3746/is_200109/ai_n8954004   (1273 words)

Greek pisciculture   (Site not responding. Last check: 2007-11-05) Growth of the sector was contributed to by a combination of the climate and geo-morphological conditions in the country that favour the cultivation of euryhaline fish, subsidies provided by the State, the reduction in fish stocks and limitations imposed on fishery. In the near future it is expected a restructuring of the sector, with the main feature being concentration at enterprise level, in order to achieve better control of production, increase in sale prices and minimization of unfair competition.

Last check: 2007-11-05) Pendrin is an anion exchanger in the cortical collecting duct of the mammalian nephron that appears to mediate apical Cl«minus»/«hco3» exchange in bicarbonate-secreting intercalated cells. The goals of this study were to determine 1) if pendrin immunoreactivity was present in the gills of a euryhaline elasmobranch (Atlantic stingray, Dasyatis sabina), and 2) if branchial pendrin immunoreactivity was influenced by environmental salinity. Immunoblots detected pendrin immunoreactivity in Atlantic stingray gills; pendrin immunoreactivity was greatest in freshwater stingrays compared with freshwater stingrays acclimated to seawater (seawater acclimated) and marine stingrays. www.uth.tmc.edu /apstracts/2002/regulatory/July/208r.html   (265 words)

Untitled Document A few elasmobranchs are euryhaline such as the freshwater sharks and sawfish of Lake Nicaragua: Carcharhinus leucas (the bull skark) and the sawfish (Pristis perotteti). These animals have the ability to regulate the production of urine, the concentration of urea, and the excretion of salts by the rectal gland (e.g., they can facultatively increase the production of urine when in freshwater by as much as 10 fold over that of marine elasmobranchs).

Hogchocker, Trinectes maculatus - Chesapeake Bay Program Trinectes maculatus, known familiarly as the hogchoker, is a small flatfish belonging to the Family Soleidae, of which there are five species in North America. Members of this species grow to a mature length of no more than 6 inches and are euryhaline, which means they can tolerate a broad range of salinities, from the salty waters at the mouth of the Chesapeake Bay to the tidal fresh tributaries farther upstream. The hogchoker is one of the most common fishes in the estuary and can also survive a wide range of conditions, including fluctuating water temperatures. www.chesapeakebay.net /info/hog_chocker.cfm   (446 words)

A range of organs are involved in elasmobranch osmoregulation, including the gill, gut, kidney and rectal gland. R.J. Balment, University of Manchester, we have attempted to identify novel genes that are differentially expressed in response to hypo- or hyper-osmotic challenge in teleost fish by the screening of micro-arrays constructed to two native euryhaline species, the eel and flounder. www.st-andrews.ac.uk /~ferg   (431 words)
