Session 59 - Impacts of Climate and Biogeochemical Extremes on Marine Organisms and Ecosystems

The Pacific oyster (Crassostrea gigas) is the broadest cultured bivalve worldwide. Managing the costal aquaculture area of Pacific oyster can increase the yield and reduce the losses caused by environment in Shandong coastal, China. With the development of remote sensing and artificial intelligence, convenient conditions are provided for the evaluation of suitability for aquaculture. This study employed a Dynamic energy budget (DEB) model and used high-resolution satellite data to analyze the suitability for Pacific oyster aquaculture in offshore Shandong. The results demonstrated that Sanggou Bay exhibits high potential for Pacific oyster year-round aquaculture. Eastern Laizhou Bay is suitable for the autumn-spring fattening culture of adult oysters. Laoshan Bay and Changshan Islands are suitable for promoting rapid growth in juvenile oysters. The results of our model were consistent with the practical oyster production value in Shandong, showing an overall increasing trend except for the anomalous value observed in 2019. Sudden drops in water temperature, red tides, and significant increases in turbidity can exert detrimental effects on oyster production, which has been evidenced to be influenced by Super Typhoon Lekima in 2019. Although this study concentrated on a specific geographical region, the model could be applied to other regions to develop market-oriented suitability management for species and environments worldwide.
