摘要
[目的]探明深圳市4个典型分布区咬齿牡蛎(Saccostrea mordax)的生物学特性、生理生化指标和营养成分,比较不同地区牡蛎的差异,为资源保护和利用提供科学依据。[方法]选择深圳市大鹏湾、东山湾、柚柑湾和西冲口4个区域采集野生咬齿牡蛎,测定其壳长、壳高、壳宽等形态学指标,检测抗氧化酶、免疫酶等生理指标,分析脂肪酸、蛋白质等营养成分。[结果]4个区域牡蛎在壳型和多个生理指标上存在显著差异。东山湾牡蛎壳型较细长,抗氧化能力和酸性磷酸酶活性较高;柚柑湾牡蛎溶菌酶活性最强,脂肪酸和糖原含量最丰富。[结论]地区环境条件是导致牡蛎差异的决定性因素,东山湾和柚柑湾牡蛎处于较高环境压力下,形成了较强的生理适应性。
[Objective]To investigate the biological characteristics,physiological and biochemical indices,and nutritional composition of wild Saccostrea mordax from four typical distribution areas in Shenzhen City,and compare the differences among oysters from different regions,so as to provide a basis for resource protection and utilization.[Method]Wild S.mordax were collected from Dapeng Bay,Dongshan Bay,Yougan Bay,and Xichongkou in Shenzhen City.Their morphological parameters including shell length,height and width were measured.Antioxidant enzymes,immune enzymes and other physiological indices were detected.Nutritional components such as fatty acids and proteins were analyzed.[Result]Significant differences were observed in shell morphology and several physiological indices among oysters from the four areas.S.mordax from Dongshan Bay had more elongated shells,higher antioxidant capacities and acid phosphatase activities.Yougan Bay oysters exhibited the strongest lysozyme activities and the highest levels of fatty acids and glycogen.[Conclusion]Environmental conditions in different regions are decisive factors leading to the variations in oysters.S.mordax from Dongshan Bay and Yougan Bay are under higher environmental pressures and have formed stronger physiological adaptability.
