CESS

Transport and Housekeeping of Calcium in Fish Gills,l uptake of ions in fresh water, therefore, requires that ions move through the cells crossing the plasma membrane barrier twice. But in the sea water environment, the branchial epithelium shows characteristics of a leaky epithelium, allowing ion movement(s) through the cells as well as along paracellular routes.

Ambient Ions and the Voltage Across Crayfish Gills,tems in fishes and crustaceans resemble those in amphibians (Kirschner et al, 1973) but the electrical pictures are very different. The purpose of this review is to describe the contributions of Na., Ca. and CI. to electrogenesis in crayfish gills the procedures for measuring the TEP in crayfish have been recently described (Kirschner, 1994).
