蛤蜊岗滩涂贝类分布及其与环境因子的关系
Spatial distribution of buried molluscs and their relationship with sediment factors in Geligang
摘要
Abstract
The mollusc community of the Geligang intertidal zone in Liaodong Bay was investigated in the spring of 2013 to identify the components, abundance, and biomass of mollusc species. A total of 16 mollusc species were identified;Bullacta exarata,Meretrix meretrix,Mactra veneriformis, andUmbonium thomasi were the dominant species andCyclina sinensisandPotamocorbula laevis were common species in the Geligang intertidal flat.U. thomasi andM.veneriformis showed the highest density distribution (83 ind/m2) and biomass (178.51 g/m2), re-spectively. The density distribution of molluscs gradually decreased from the northern part of the intertidal flat to the southern zones, and it was higher in the round intertidal zone than in the central zone of the Geligang flat. Based on the number of species and environmental factors according to Person correlation analysis, the median grain size and organic matter of the sediment had a great effect on the distribution ofM.meretrix andU.thomasi. Our results showed that the Geligang intertidal flat is an important shellfish fishery, and the high abundance and biomass ofU. thomasi can be exploited for future uses. In addition, measures should be taken to protect and restore the population of the clamM.meretrix.关键词
