| 摘 要： | 清滤率(Clearance rate, CR)与滤食性贝类生长发育密切相关,采用Box-Behnken设计(BBD)和响应曲面法,在实验室条件下研究了温度(18-34℃)、盐度(20-40)和pH(6.5-9.5)对马氏珠母贝(Pinctada martensii)稚贝清滤率(CR)的联合效应,旨在建立温度、盐度和pH对马氏珠母贝稚贝清滤率的定量关系模型,并通过统计优化方法得出温度、盐度和pH的最佳组合。结果表明:温度的一次效应、温度和pH的互作效应、盐度和pH的互作效应以及温度、盐度和pH的二次效应对马氏珠母贝稚贝清滤率的影响均极显著(P<0.01);盐度的一次效应、pH的一次效应以及温度和盐度的互作效应对清滤率无显著影响 (P>0.05)。实验得出的清滤率模型决定系数为0.9950,预测决定系数为0.9284,表明该模型建立有效并可用于预测马氏珠母贝稚贝的清滤率。通过采用优化方法得出,在温度26.95℃,盐度29.69,pH8.09时,稚贝清滤率达到最大,最大值为1.4894×10-3L/h,满意度为0.9886。研究结果可为马氏珠母贝滤食生理研究及稚贝培育提供理论依据。
