The eel is a euryhaline teleost. In order to maintain osmotic equilibrium the animal must resist loss of body water and solutes to the sea, and to resist volume expansion from influx of free water in fresh water (FW) environments. The epithelial contact surfaces of the eel are prime sites for water and solute exchange and the gill with its high surface area for gas exchange represents a vulnerable site for osmotically driven uptake or loss of body water1. Likewise, the gastrointestinal tract must employ ion exchange and water transport mechanisms which permit volume homeostasis6.
