## Abstract Blood PO~2~ in the blue crab __Callinectes sapidus__, a very active species of tropical origin, is lower at 22Β°C than that of larger crabs in colder waters. These low oxygen levels permit its hemocyanin to be highly oxygenated at the gill, and to deliver almost half of its oxygen to the
Carbonic anhydrase (CA) activity in the gills of the euryhaline blue crab, Callinectes sapidus, was measured in response to acute low-salinity transfer and treatment with eyestalk ablation (ESA) in an attempt to elucidate potential regulatory mechanisms of salinity-mediated CA induction. ESA alone r
## Abstract The effects of inorganic ions and of the hydrogen ion on oxygenβbinding properties of most respiratory pigments are opposite. The addition of salt to the medium increases oxygen affinities, and the addition of H+ decreases oxygen affinities of crustacean hemocyanins. These oxygenation p
