Teleosts in temperate climates have the extra challenge of living in an environment in which ambient temperatures range from 0-30°C. It was hypothesized that 1. Na+ absorption through the gills occurs via a protein homologous to mammalian Na+/H+ exchanger (NHE), 2. Na+ is exchanged for NH4+—the nitrogenous waste product of the fish—rather than H+, and 3. gill proteins from 5°C winter-acclimated fish (WA) would be more active than those from 20...
