The post-feeding alkaline tide (elevated blood pH and HCO3-) has been well characterised in air-breathing animals, but to date this phenomenon has only been demonstrated in one piscine species, a marine elasmobranch. We have investigated the acid-base and ion regulatory responses of a freshwater teleost to voluntary feeding as well as to involuntary filling(More)
A Xenopus oocyte heterologous expression system was used to characterise iron transport properties of two members of the solute carrier 11 (slc11) protein family isolated from rainbow trout gills. One cDNA clone differed from the trout Slc11alpha containing an additional 52bp in the exon between transmembrane domains (TM) 10 and 11. The 52bp contained a(More)
In the marine teleost intestine the secretion of bicarbonate increases pH of the lumen (pH 8.4 -9.0) and importantly reduces Ca2+ and Mg2+ concentrations by the formation of insoluble divalent ion carbonates. The alkaline intestinal environment could potentially also cause essential metal carbonate formation reducing bioavailability. Iron accumulation was(More)
