摘要:

在实验室条件下,用流水装置测定了体质量、昼夜节律、藻密度和流速对沟纹巴非蛤（Paphia exarata Philippi）滤水率的影响。结果表明:（1）单位体质量滤水率随个体体质量的增加而减小,二者之间呈负幂函数关系:R_f’=0.657w^-0.6501。（2）在1个昼夜里,测定了00:00、04:00、08:00、12:00、16:00、20:00共6个时间点的滤水率,滤水率在00:00时最小、08:00时最大,二者差异显著（P<0

Study on the filtration rate of Paphia exarata Philippi

Abstract:

The filtration rate of Paphia exarata was determined by flowing tanks. The results are shown below:（1） The relationship between filtration rates and individual weight shows a exponential function (R_f=0.657w^{-0.349 9}, R_f’=0.657w^-0.6501).（2） The maximal and minimal filtration rate occurred at 24h interval period. The maximum was at 08:00,which was significantly higher than the minimum at 00:00 （P<0.05）.（3）The filtration rate increased with higher concentrations of diet but decreased if the concentration exceeded a definitive value （（4.5±0.11）×10⁴ cell/mL）.（4） The filtration rate increased with the increase of the flowing velocity in the range of 3.6～9.0 L/h but it increased no significantly if the flowing velocity exceeded 7.2 L/h.
