[目的]分析长砗磲个体大小与虫黄藻数量的关系。[方法]以采自海南东瑁洲岛的28只长砗磲为试材,用SAS统计软件对长砗磲体内的虫黄藻数量和叶绿素a含量与壳长和干重进行相关性分析。[结果]长砗磲体内的虫黄藻总数随着长砗磲壳长和干重的... [目的]分析长砗磲个体大小与虫黄藻数量的关系。[方法]以采自海南东瑁洲岛的28只长砗磲为试材,用SAS统计软件对长砗磲体内的虫黄藻数量和叶绿素a含量与壳长和干重进行相关性分析。[结果]长砗磲体内的虫黄藻总数随着长砗磲壳长和干重的增加均呈对数增长,与壳长的相关系数为0.967 2(P<0.01),与干重的相关系数为0.934 0(P<0.01),二者均表现极显著相关性。长砗磲体内的总叶绿素a含量随着壳长的增长而增加,其相关系数为0.936 7(P<0.01),二者亦具有极显著相关性,但单个虫黄藻细胞内叶绿素含量不随长砗磲个体的增大而增加,而是保持了1个恒定值2.5(±0.32,n=28)pg/cell。[结论]长砗磲通过增加体内虫黄藻的数量来增加光合作用产物的总量,以满足自身生存与生长的需要。 展开更多

In Egypt, Tridacna Maxima are found in Gulf of Suez, Gulf of Aqaba and Red Sea. Tridacna Maxima are very important ecological species as seafood source and as a substrate for reef-associated organisms;therefore we should protect it from extinction. Recently, these species are exposed for many factors of pollution (human activities, tourism and natural resources) that affect the distribution and abundance of it. The main objective of this research is to shed some light on the origin, stratigraphic position, systematic palaeontology and geographic distribution of Tridacna Maxima. In addition to their ecologic and environmental conditions were discussed. Finally, a proposed rules for protection these species from extinction were listed. Individuals of Tridacna Maxima were collected from different sites along the red Sea coast. 展开更多
