The seasonal filtration, ingestion and biodeposition rates were in situ measured, and carbon (C), nitrogen (N) and phosphorus (P) budgets of Meretrix meretrix throughout the year were modeled. The results indicated that the scope for growth of M. meretrix in carbon (SFGC), nitrogen (SFGN), and phosphorus (SFGP) all ranged significantly among seasons, and the peak values were detected in summer. Among them, SFGCwas negative in spring, SFGN and SFGP were always positive thorough the year. The seasonal ranges of SFGC, SFGN, and SFGP were -2.11~18.59mg C/(ind·d), 0.13~5.87mg N/(ind·d), and 0.11~1.45mg P/(ind·d), respectively. Distinct seasonal patterns were shown among the net growth efficiencies in carbon (KC2), nitrogen (KN2), and phosphorus (KP2), and ranked as KN2 > KP2 > KC2. Furthermore, the carbon budgets in spring and autumn was in the following order:the C loss from fecal production (FC) > the C loss from respiration (EC) > the C loss from growth (GC), and in summer was in the following order: GC > EC > FC, in winter was in the following order: GC > FC > EC. The nitrogen and phosphorus budgets were ranked as follows:the N used for growth (GN) > the N loss from fecal production (FN) > the N loss from excretion (EN), The P used for growth (GP) > the P loss from fecal production (FP) > the P loss during excretion (EP), respectively. The C, N, and P budgets illustrated that more N and P than C were consumed for growth and the pelagic primary production was transferred efficiently to a higher trophic level. This study suggests that M. meretrix population may play a key role in the nutrient cycle of the estuarine ecosystem, and should be considered an important component of the ecology of estuaries.
