| Abstract |
The ionic permeabilities of the isolated gill cuticle have been deduced from diffusional transcuticular potential and conductance measurements in several species of decapod crustaceans. It is established that the cuticle permeability depends upon the species considered and its ionoregulation capability, upon the localization of the gill in the chamber or even upon the topographic region in a single gill and upon the nature of the ionic species. In each case the cuticle must always be considered as a diffusion barrier for the main osmotic effectors, Na+ and Cl-. |
