| 摘 要： | 于2009年8月—2010年7月对渤海辽东湾高家滩沿海滩涂贝类资源进行了周年调查。结果表明：在高家滩沿海共采集滩涂贝类37种,分别隶属于2纲、3亚纲、8目、19科、29属,主要经济贝类有菲律宾蛤仔Ruditapes philippinarum、西施舌Mactra antiquata、大竹蛏Solen grandis、四角蛤蜊Mactra veneriformis、文蛤Meretrix meretrix 5种,占滩涂贝类总现存资源量的81.75%;平均栖息密度为508.9个/m2,平均生物量为412.27 g/m2,现存量为3 021.94 t,生物量季节性变化明显;贝类生态分布特点,依不同潮间带区域呈带状分布,高潮带为马蹄螺科群落,中潮带为蛤仔-西施舌群落,低潮带为文蛤-竹蛏群落,春夏贝类主要分布于高潮带外缘至低潮带,秋冬分布于中潮带至深度基准面,迁徙趋势明显。在调查高家滩滩涂贝类资源现状的基础上,提出了对资源合理利用和增殖保护的措施。
