2013年至2019年在闽江口进行了11个航次共38个断面的潮间带大型底栖动物调查研究,共发现潮间带生物195种,隶属10个门类,主要以甲壳类、软体动物和多毛类为主.敖江入海口潮间带生物的物种多样性、生物量和丰度均显著高于闽江入海口,且敖江入海口潮间带生物的多样性指数(H\')、均匀度指数(J\')和丰富度指数(D)也均显著高于闽江入海口.闽江口潮间带生物的物种数、丰度和生物量在中、低潮区均显著高于高潮区.闽江入海口潮间带的优势种以小型蟹类为主,敖江入海口潮间带的优势种包括多毛类、软体动物和蟹类,其中经济种类菲律宾蛤仔(Ruditapes philippinarum)和焦河蓝蛤(Potamocorbula us-tulata)为敖江入海口的主要优势种.敖江入海口的潮间带生物需要更多的关注和研究.
