摘要
在实验室的条件下.研究盐度(16、24、32、40)对不同规格(A:(50.79±3.24)cm,B:(42.24±0.78)cm,C:(34.82±1.51)cm)的毛蚶(Arca subcrenata Lischke)耗氧率(R_0)(mg·g^(-1)·h^(-1))、排氨率(R_n)(μg·g^(-1)·h^(-1))的影响。实验表明:在实验盐度(16～40)范围内,毛蚶的耗氧率(R_0)和排氨率(R_n)与软组织干质量(0.27～1.81g)呈幂指数关系,符合公式R= aW^b,其单位体重的耗氧率和排氨率在盐度为32时达到最大,而后随着盐度的升高其值逐渐减小。
Effects of salinity on oxygen consumption rate（mg·g^-1·h^-1 ） and ammonia execration rate（μg·g^-1·h^-1） of Arca subcrenata was studied in laboratory. The results indicate that the oxygen consumption rate and ammonia execration rate are correlated positively with water salinity. Under the test salinity （16--40）, the oxygen consumption rate, ammonia excretion rate also increase with the increasing salinity, and reach the peak value at 32, then the value decreases with the salinity beyond 32. The result of ANOVA shows that salinity, dry weight and their interaction have significant effect on the oxygen consumption rate and ammonia execration rate.
