【摘要】：为探讨天津汉沽鲤鱼门潮间带经济贝类资源的变化特征,2012~2014年作者对该滩涂经济贝类开展资源调查,并与2008年的调查结果进行对比分析。结果表明:2012~2014年经济贝类种数分别为9种、10种、10种,高于2008年的7种;鲤鱼门滩涂经济贝类主要分布于中潮区,2012~2014年中潮区经济贝类资源量分别为1 082.8、1 183.9和1 339.8g/m2,高于2008年的293.5 g/m2;2012~2014年优势种为菲律宾蛤(Ruditapes philippinarum)仔,优势度90%以上,2008年优势种为四角蛤蜊(Mactra veneriformis);近年来菲律宾蛤仔大量出现,与邻近海域的大规模增殖放流活动密切相关。
[Abstract]:In order to study the variation characteristics of the economic shellfish resources in the intertidal zone of Liyumen in Tianjin, the authors investigated the resources of the economic shellfish in the tidal flat from 2012 to 2014, and compared with the results of the survey in 2008. The results showed that the number of economic shellfish species from 2012 to 2014 was 9 species, 10 species and 10 species respectively, which was higher than that of 7 species in 2008. The resources of economic shellfish were 1 082.8g / m ~ (2) and 1 339.8g / m ~ (2), respectively, which were higher than the dominant species (Ruditapes philippinarum) from 293.5 g / m ~ (2) in 2008 to 2014 (P < 0.05). The dominant species was Mactra veneriformisus in 2008, and the large number of clam larvae appeared in recent years, which was closely related to the large-scale proliferating and releasing activities in the adjacent waters.
