摘要：

1. 1. Salinity and temperature influence blood osmoconcentration of adult Callinectes sapidus Rathbun. Osmoregulation is possible over a wide salinity range, but hyporegulation is exhibited only at high temperatures. 2. 2. An inverse relationship exists between temperature and blood concentration. A seasonal effect persists under experimental conditions of constant temperature. 3. 3. Male crabs have lower blood concentrations than females at salinities below 20% except at extreme dilutions. 4. 4. Both sexes exhibit hysteresis-like response at salinities above 15%. Blood concentration after acclimation is higher when a given salinity is approached from a higher salinity than when approached from a lower one. 5. 5. Total organic substances and ninhydrin reactive substances in the blood vary without apparent relation to blood osmoconcentration. Inorganic substances change with blood concentration. © 1969.
