摘　　要：在实验条件下,采用静水方法,测定了水温11.5、22.5、28.0、32.0℃下,硬壳蛤的滤食率、耗氧率和排泄率。结果表明,在11.5～22.5℃之间,硬壳蛤的上述生理指标随温度的升高而增加,差异显著。而在22.5、28.0、32.0℃之间,生理指标的差异并不十分显著,间接说明了硬壳蛤对温度的较强适应能力,适合在浙江省等东南沿海进行推广养殖。The filtration rate, oxygen consumption rate and ammonia excretion rate of Mercenaria mercenaria were measured at 11.5, 22.5, 28.0 and 32.0℃ in lab static systems. The results showed that their physiologic and ecologic values increased with increasing temperature between 11.5 and 22.5℃ showing significant differences. But at 22.5, 28.0 and 32.0℃, no significant difference was shown. The conclusion showed that M. mercenaria has strong ability to adapt high temperature environment, and it is farmable in southeastern coast of China.
