Abstract

1. Cold-acclimated (1 degree C) goldfish (Carassius auratus) branchial Na/K-ATPase activity was elevated 100% while renal Na/K-ATPase activity was not significantly affected compared with warm-acclimated (20 degrees C) goldfish. 2. Cold-acclimated goldfish branchial and renal Mg-ATPase activity was reduced 18 and 30% on a per mg protein basis, respectively. 3. Renal Na/K-ATPase activity was 4.6- and 1.6-fold greater than gill in cold- and warm-acclimated fish, respectively. 4. The elevated branchial Na/K-ATPase activity and the unchanged renal Na/K-ATPase activity are consistent with the maintenance of the reduced blood ion level in cold-acclimated goldfish.
