Experiments on Gulf toadfish Opsanus beta demonstrate how feeding impacts osmoregulation in the marine teleost intestine. A high Ca(2+) diet of pilchards Sardina pilchardus ([Ca(2+)]=404.2 mmol… (More)
Marine teleosts have extracellular fluids less concentrated than their environment, resulting in continual water loss, which is compensated for by drinking, with intestinal water absorption driven by… (More)
Although endogenous CO2 hydration and serosal HCO3- are both known to contribute to the high rates of intestinal HCO3- secretion important to marine fish osmoregulation, the basolateral step by which… (More)

Simultaneous measurements of all major electrolytes including HCO3(-) and H+ as well as water demonstrated that fluids absorbed by the anterior intestine of the marine gulf toadfish under in… (More)
Anion exchange contributes significantly to intestinal Cl(-) absorption in marine teleost fish and is thus vital for successful osmoregulation. This anion exchange process leads to high luminal… (More)
Pyloric caeca and anterior intestine epithelia from seawater-acclimated rainbow trout exhibit different electrophysiological parameters with lower transepithelial potential and higher epithelial… (More)
The effects of feeding on both acid–base and ion exchange with the environment, and internal acid–base and ion balance, in freshwater and seawater-acclimated flounder were investigated. Following… (More)

This review addresses an often overlooked aspect of elasmobranch osmoregulation, i.e., control of body fluid volume. More specifically the review addresses the impact of changes in blood volume in… (More)
