| 摘要: |
| 2008年10月~2009年1月,以扁藻(Platymonas subcordiformis)为饵料,在实验室条件下采用静水法研究不同饵料浓度、不同体重和不同温度对马氏珠母贝(Pinctada martensii)滤水率的影响。结果表明:在适宜的饵料浓度范围内,小贝、中贝和育珠贝的滤水率随着饵料浓度的增加而增大,饵料浓度和滤水率之间均呈正相关的幂函数关系;体重对滤水率的影响呈幂函数关系:FR=2.6725W0.1388(R2=0.8754),滤水率随着体重增加而增大;在一定温度范围内,滤水率随温度升高而增加,25℃时滤水率达到最大值,随后随着温度升高滤水率呈下降趋势。 |

| Abstract: |
| With Platymonas subcordiformis as food, the effects on the filtration rate of Pinctada martensii under different algae concentrations, weight and temperatures were studied in a laboratory static system by the stagnant water method from October 2008 to January 2009.The results indicated that within a certain range of algae concentrations, the filtration rate of P.martensii increased as the algae concentration increased that can be described by functional relation.The filtration rate of P.martensii was related to dry weight described by power function relation (FR=2.6725W0.1388), and the filtration rate of P.martensii increased with higher temperature but decreased if the temperature was over 25℃. |
