...Till S. Harter; Christian Damsgaard; Matthew D. Regan ABSTRACT The gill is the primary site of ionoregulation and gas exchange in adult teleost fishes. However, those characteristics that benefit diffusive gas exchange (large, thin gills) may also enhance the passive equilibration of ions and water...
