| 摘要: |
| 于1997年6月－1998年5月用现场方法测定了烟台四十里湾海区总颗粒物质（TPM）、颗粒有机物（POM）现存量和栉孔扇贝同化率（AE）周年变化，并分析了栉孔扇贝同化率与海区温度、盐度、TPM和POM的关系。结果表明，(1)整个海区TPM现存量秋季最高，其次为春季和冬季，夏季最低。海区POM含量变化不大，在1.34–1.65mg/L之间。栉孔扇贝同化率在春、夏、秋三季较高，冬季较低，其中在秋末冬初（11月）最低；(2)栉孔扇贝同化率与温度有明显相关性，与盐度相关性不大；(3)栉孔扇贝同化率与海区TPM和POM现存量呈负相关关系，回归方程分别为AE=79.694[TPM]-0.6332
(R2=0.7955)和AE=52.843[POM]-1.1097(R2=0.6925)。 |

| Abstract: |
| Absorption efficiency (AE) is an important parameter in bioenergetic studies of suspension-feeding bivalves. During June 1997–May 1998, we determined the annual variations of total particulate matter (TPM) biomass, particulate organic matter (POM) biomass and AE of the scallop Chlamys farreri in Sishiliwan Bay, Yantai, with in situ method, and studied the relationships between AE and seawater temperature, salinity, TPM, POM. The results suggest that: (1) POM biomass in fall is the highest of all seasons, the next is in spring and the lowest is in summer, the POM biomass is not significantly different among seasons (1.34–1.65mg/L); AE of C. farreri is high in spring, summer and fall, is low in winter, especially in November. (2) AE is significantly correlated with water temperature, but poorly correlated with salinity. (3) AE is negatively correlated with TPM and POM biomass, the regression formula are AE==79.694[TPM]-0.6332(R2=0.7955) and AE=52.843[POM]-1.1097(R2=0.6925), respectively. |
