| Résumé : |
This study primarily aims to estimate bioenergetic parameters by applying an innovative model, the Dynamic Energy Budget (DEB) theory, which makes it possible to link environmental conditions to individuals’ physiological responses.
A total of 229 specimens of the species Crassostrea gigas were collected between January and May 2025. Growth was modeled using the Von Bertalanffy function, expressed by the following equation:
L(t)=26,8×(1-e^(-0,85*(t+0,2) ))
The analysis of the length–weight relationship revealed a minorant allometry, indicating a faster increase in length compared to body weight.
Bioenergetic parameters were estimated using the DEB model, allowing the description of growth as a function of temperature in the farming area. Finally, a simulation was carried out to study the combined influence of temperature and trophic availability on growth dynamics.
The results obtained show a correlation between temperature and growth. Moreover, trophic availability, in interaction with other environmental parameters, plays a key role in modulating growth rates and biomass yields of Crassostrea gigas oysters.
