| 摘 要： | 凸壳肌蛤(Arcuatula senhousei)是虾蟹等养殖品种的优质饵料生物,也是极具养殖潜力的贝类品种。为了深入了解其生理代谢,利用室内静水法对不同温度(7℃、15℃、23℃、31℃)凸壳肌蛤的摄食率、排粪率、耗氧率、排氨率等生理指标进行了研究,并建立了能量收支方程。结果显示,23℃时的滤水率、摄食率、耗氧率、同化效率均显著高于其他温度梯度(P0.05),分别达到了1.09 L/(g·h)、24.46 mg/(g·h)、3.50 mg/(g·h)和62.93%;7℃时的滤水率、摄食率、耗氧率、排粪率、排氨率均低于其他温度梯度,分别为0.24 L/(g·h)、6.04 mg/(g·h)、1.02 mg/(g·h)、4.20 mg/(g·h)、2.33μmol/(g·h)。且滤水率、摄食率、耗氧率、同化效率随着温度升高都呈先升高后下降的趋势,在23℃时均达到最高值。不同温度下的能量收支方程为:100C=58.12F+46.74R+2.54U–7.40P(7℃);100C=44.28F+29.14R+1.85U+24.73P(15℃);100C=17.18F+41.81R+6.64U+34.37P(23℃);100C=53.35F+28.26R+14.66U+3.73P(31℃)。能量收支研究表明,生长能(P)、呼吸能(R)、排泄能(U)和粪便能(F)占摄食能(C)的比例分别为–7.4%~34.37%、28.26%~46.74%、1.85%~14.66%、17.18%~58.12%,23℃时生长能占摄食能的比例显著高于其他温度梯度(P0.05),达到了34.37%;7℃时最低,为–7.40%。研究结果为深入了解凸壳肌蛤的生理能量学提供了数据支撑。
