| Abstract | : | Long-term observations of pH and temperature are a key element to project the future impact of these pressures. Near-shore productive environments where important shellfish farming activities are conducted, are supposed to present pH levels and amplitudes of daily and seasonal variation that are very different from those in the open ocean. A French high-frequency observation network was initiated in 2021 in the framework of the CocoriCO2 project. Along the littoral, six sites were chosen based on their importance in terms of shellfish production and the presence of low frequency monitoring activities. In each site, pH loggers were deployed, next to CTD probes, both inside and outside shellfish farms. While this network has been running for more than two years, the acquired data set has already revealed important differences in terms of pH variations between monitored sites. In parallel, an experimental unit consisting of a 20-foot container, with 12 x 250 liter tanks, equipped with a device for controlling water temperature, pH and photoperiod was installed at the proximity of oyster farms in the Thau lagoon (France). From October 2022, oysters and mussels are kept under ambient conditions and under pH and temperature conditions expected for 2050, 2075 and 2100 in triplicate following the SSP2-4.5 CO2 emission scenario. Individuals will be kept in culture for 12 to 15 months, and monitored in terms of growth, survival, physiological state (energy balance), calcification and nutritional value (protein content, carbohydrates, lipids and essential fatty acids). |
