2017年,广西水产科学研究院对岩滩库区的9个断面进行了为期1年的淡水壳菜分布监测。监测结果表明:淡水壳菜在岩滩库区主要附着在养殖设施上,调查的7 种附着基底中,底泥基本没有淡水壳菜分布。锚绳是淡水壳菜主要的发生源区,附着密度和生物量最高,平均体长和平均体重最大。春季和夏季淡水壳菜的密度和生物量较高,秋季和冬季平均体长和平均体重较高。上游断面的壳菜附着量低于下游断面。附着基的数量和青鱼的摄食压力,是淡水壳菜扩增的主要限制因素。

Abstract: In 2017, a survey on the distribution of freshwater mussel for one year in nine sections of the Yantan reservoir area wasconducted by the Guangxi Aquaculture Science Research Institute. The monitoring results show that in the surveyed seven adheringbasement of Yantan reservoir, the freshwater mussels mainly stick to the aquaculture facilities and hardly any mussel is in the mud.Anchor rope is the main growth area with the highest density and biomass of the freshwater mussels whose average length is longest andwhose average weight is largest. The density and biomass of the mussels is higher in spring and summer, and the values of average lengthand average weight of them are larger in autumn and winter. The adhesion amount on the upstream section is lower than that on thedownstream section. The adhesion amount and the ingestion of black carp are the main limiting factors of freshwater mussel growth inthe reservoir.
