【摘要】 在实验室条件下,测定了巨牡蛎在不同个体大小、不同个体数和不同密度单胞藻(三角褐指藻)密度不同水平条件下的滤水率。结果:(1)在上述三个影响因素中,单胞藻的密度对巨牡蛎的滤水率影响最大;(2)巨牡蛎单位体重滤水率均随着巨牡蛎个体数量、巨牡蛎大小及单胞藻密度的增大而下降,它们的关系呈负指数函数和负幂函数关系;(3)在本实验条件下,当三角褐指藻的密度为1.0×104/mL,巨牡蛎的干肉重和个体数分别为0.1114 g和10只时,巨牡蛎的滤水率最高,达2.693 L/h.g。更多还原

【Abstract】 The filtration rate of Crassostrea sp.affected by three factors and different levels were studied in laboratory system.The results showed:(1) The density of manodian algae,Phaeodactylum tricofnutum,among three influencing factors is the biggest effect on filtration rates of Crassostrea sp.(2) The filtration rate of each gram oyster decreased with increasing of oyster number,oyster size and density of manodian algae,and the relationship between them showed a negative exponential or index function,respectively.(3) When the density of manodian algae was 1.0×10~4 /mL,dry weight of oyster was 0.1114g and oyster was 10 individuals,the filtration rate of each gram oyster was the highest,up to 2.693 L/h·g.更多还原
