Abstract: This study constructed a Dynamic Energy Budget (DEB) model to gain a deeper understanding of the growth, repro-
duction, and energy allocation of oyster Saccostrea mordax in different marine areas, providing theoretical support for the site
selection, design, and sustainable management of oyster reefs. Through model construction and validation, the research
explores the impact of environmental factors such as water temperature and chlorophyll concentration on oyster growth, offer-
ing technical guidance for optimizing oyster farming strategies as well as marine ecosystem protection and restoration. Seven
basic parameters required for the DEB model were measured through indoor physiological experiments, while other parameters
were obtained from literature and model calibration. The shape coefficient (δ m ) was determined by regression analysis of shell
length and soft tissue wet weight. Based on the measured oxygen consumption rates of oysters at different temperature condi-
tions, the arrhenius temperature (T A ) was calculated. After 45 days of starvation experiments, volume-specific costs for struc-
ture [E G ], and maximum storage density [E M ], volume-specific maintenance rate [Ṗ M ] were obtained. Maximum feeding rate
per unit body surface area {J̇ Xm } and maximum surface area-specific assimilation rate {Ṗ Am }. Remote sensing technology was
used to obtain chlorophyll-a concentration and water temperature from June 2022 to April 2024 at Mischief Reef and Daya
Bay. These data were used as forcing functions, and an individual growth model of the S. mordax in Daya Bay was constructed
using R software and validated against actual growth data from Mischief Reef. Seven basic parameters required for the DEB

model were successfully measured in indoor experiments, with δ m = 0.270, T A = 4 900.01 K, [E G ] = 5 600 J/cm , [E M ] = 6 382

J/cm , [Ṗ M ] = 26 J/(cm ·d) {Ṗ Am } = 244 J/(cm ·d) and {J̇ Xm } = 325 J/(cm ·d). The model simulation results showed a signific-
ant linear relationship between the simulated values of soft tissue dry weight and shell height and the measured values, demon-
strating the effectiveness of the DEB model in this experiment. Regarding the growth of the S. mordax, the model indicates that
food limitation has a higher impact than water temperature. The constructed DEB model can effectively simulate the individual
growth of S. mordax. The temperature and food conditions at Mischief Reef are more suitable for the growth of S. mordax than
those at Daya Bay.
