摘要
分别于2008年9月和2013年9月对天津独流碱河河口潮间带的贝类资源进行了调查。结果表明,2013年该区域贝类种类组成有2纲、3亚纲、4目、12科、18种,其中经济价值较高的种类为菲律宾蛤和青蛤,主要分布于中潮带,栖息密度分别为112.7粒/m2和12.0粒/m2,平均生物量分别为334.1 g/m2和86.0 g/m2,商品率分别为36.4%和22.2%。2008年,该区域共有贝类15种,未见菲律宾蛤仔与青蛤。蛤仔与青蛤的大量出现可能与近年来邻近海域的大规模增殖放流活动密切相关。
The shellfish resources survey of intertidal zone of Duliujian river estuary in Tianjin was carried out in september 2008 and 2013, respectively. The results show that the shellfish species in this area included 2 classes, 3 subclasses, 4 orders, 12 families and 18 species, among these species, the economic values of Ruditapes philippinarum and Cyclina sinensis distributed mainly in the middle tidal zone were higher, and the habitat densities of two species were 112.7 ind/m2 and 12.0 ind / m2, the average biomass was 334.1 g/m2 and 86.0 g/mz, and the commodity rates were 36.4% and 22.2%, respectively. The shellfish of this area in 2008 was 15 species, and Ruditapes philippinarum and Cyclina sinensis were not found. The high densities of Ruditapes philippinarum and Cyclina sinensis were closely related to enhancement and release of shellfish in surrounding waters in recent years.
