摘要：

Specimens of the West African blood clam Anadara senilis were exposed to both sinusoidal and abrupt salinity regimes. Measurements showed that haemolymph osmolality and concentrations of Na, K+, Ca2+ and Mg2+ followed the concentrations of the external medium up to the time of shell valve closure. Shell valves closed when the seawater concentration had fallen to about 15.4% S and reopened at a similar salinity. The closure mechanism was effective in preventing excessive haemolymph dilution. © 1979 Springer-Verlag.
