Remote sensing and Dynamic Energy Budget-driven Crassostrea gigas autumn-winter fattening aquaculture suitability assessment in Shandong Peninsular
为了优化山东半岛近海长牡蛎秋冬季育肥养殖的空间格局,本研究采用卫星遥感获取的海水表层温度、叶绿素a浓度和悬浮颗粒物浓度数据,以及海水表面高度再分析数据,基于动态能量收支(Dynamic Energy Budget,DEB)理论,构建了山东半岛长牡蛎秋冬季育肥养殖适宜性评价模型,通过对山东半岛海域长牡蛎养殖适宜性指数的时空变动分析发现,适宜性呈现南部海域＞北部海域＞东部海域＞西部海域的趋势,其中南部海域非常适宜的区域面积占比最大,为9.1％,主要分布在乳山地区;山东半岛西部黄河口周边海域存在大面积的不适宜养殖区域,占比高达该海域的30.5％.长牡蛎秋冬季育肥养殖的非常适宜区域在2017年和2019年分别占总近海面积的38.2％和57.9％,显著高于其余年份.通过实地验证发现,山东长牡蛎的秋冬季育肥养殖最适宜海区具备水体浑浊度较低、叶绿素浓度较高、温度较暖且风浪较小的特征.本研究结果可以为山东半岛长牡蛎养殖规划提供有效的量化依据和理论基础.
Pacific oyster(Crassostrea gigas)is a widely aquaculture shellfish in China.Managing the coastal aquaculture area of C.gigas can increase the yield and reduce the losses caused by the environment in Shandong.With the development of remote sensing and artificial intelligence,convenient conditions are provided for evaluat-ing suitability for aquaculture.The autumn-winter fattening aquaculture is an efficient aquaculture method for Pacific oysters.In this study,based on Dynamic Energy Budget(DEB)theory,sea surface temperature,chloro-phyll-a and total suspended sediment data obtained by satellites and sea surface height reanalysis data,were used to construct an evaluation model for C.gigas suitability assessment in Shandong Peninsula.The results showed regional differences on the suitability index of fattening aquaculture in Shandong Peninsula,and the overall suitab-ility trend was southern coastal area＞northern coastal area＞eastern coastal area＞western coastal area.The most suitable aquaculture area in the southern coastal area was 9.1％,mainly in Rushan coastal.Several area in the Yel-low River mouth area were unsuitable aquaculture area,accounting for as much as 30.5％of the area.The most suitable area of C.gigas fattening aquaculture in Shandong costal area was 38.2％in 2017 and 57.9％in 2019,much more than those of other years.The autumn-winter fattening aquaculture in Shandong for C.gigas was bet-ter located in areas with less turbidity,higher chlorophyll-a concentrations,warmer temperatures and fewer waves.The Yellow River estuary was not suitable for the autumn-winter fattening aquaculture due to the high turbidity.The northern and northeastern coastal area of Shandong,such as the northern part of Yantai City and the eastern part of Rongcheng City,were suitable for the fattening aquaculture due to the abundance of Chl.a and clarity of water.In the southern coastal area of the Shandong,such as the southern part of Qingdao City and the southern part of Lushan City,SST was warmer in autumn and winter,allowing oysters to continue to grow and develop,which was ideal for fattening.The results of this study can provide effective quantification and scientific basis for C.gigas aquaculture suitability assessment in Shandong Peninsula.
