Aquaculture is one of the fastest growing sectors in global seafood production. Previous studies have identified oysters' vulnerability to increasing atmospheric CO2 and ocean acidification, while few studies have investigated the feedback of oyster aquaculture on carbon emission and carbonate chemistry. In Narragansett Bay, Rhode Island, USA, the local aquaculture industry has observed a worrisome trend: high oyster mortality in recent years. Through a collaborative effort with local oyster farmers in Narragansett Bay, we aim to better understand the drivers of this aquaculture trend. We initiated a high-temporal resolution time series of baseline environmental data to measure the natural variability of temperature, salinity, dissolved oxygen, chlorophyll, and pH near 10 oyster farms in lower Narragansett Bay. Additionally, we deployed juvenile and adult oysters in traditional surface and bottom gear and newly approved alternative surface gear to monitor growth and respiration. In the first observation season, summer 2024, growth measured as shell height in both types of surface deployment was .0986 mm day-1, more than double the rate of the oysters measured from bottom deployment. The preliminary results also showed significant biogenic calcification in summer months, determined from the Total Alkalinity (TA) and Dissolved Inorganic Carbon (DIC) anomalies compared to conservative mixing curves. The average TA anomaly due to calcification was -39 µmol kg-1 when temperature was >19 °C, while net dissolution, or positive TA anomaly (+28 µmol kg-1), was observed in cold season (<14°C), a sign of corrosive and stressful conditions for bivalves in Narragansett Bay. Analyses estimated the annual cycle of carbonate chemistry changes, including air-sea CO2flux near the oyster aquaculture sites, while the annual archived oyster landing data were used to cross-check the mass balance estimation. Through examining the impact of environmental factors on oyster growth rates, and oysters’ feedback to the surrounding carbonate system, this study benefits our understanding of the limitation and sustainability of the expanding aquaculture in coastal regions.
