摘要:
本文对采自三门湾泥滩、沙滩、岩礁潮间带的主要经济贝类彩虹明樱蛤、缢蛏、僧帽牡蛎、青蚶、光滑河篮蛤胃含物中的微、小型藻类组成进行了鉴定分析。结果表明,5种经济贝类胃含物中共鉴定出微、小型藻类143种,其中,硅藻占75.5%;甲藻占12.6%;绿藻门和金藻门占5.6%;蓝藻门和隐藻占4.2%;其他类占2.1%。胃含物中出现的细胞个体中,小于20 μm的主要微型藻类是中肋骨条藻、盔状舟形藻、尤氏直链藻、小环藻、海链藻等;细胞个体大于20 μm的主要小型藻类是琼氏圆筛藻、海生斑条藻、短柄曲壳藻、钝角齿状藻等。

Abstract:
In this paper, the nano- and microalgal contents of the stomachs of the main economic shellfish of Sanmen Bay, China, were identified and analyzed. Five species, including Iridona iridescens, Sinonovacula constricta, Saccostrea cuccullata, Barbatia virescens and Potamocorbula laevis were collected from the mudflats, beaches, and rocky reefs of the bay for analysis. Study results revealed a total of 143 species of nano and microalgae identified in the stomach contents of these five economic shellfish. In these species, diatom accounted for 75.5%, dinoflagellate 12.6%, green and gold algae 5.6%, cyanobacteria and cryptophyta 4.2%, and other categories, 2.1% of the stomach contents. In the individual cells presenting in the stomach contents, the main nanoalgae smaller than 20 micrometers were Skeletonema costatum, Navicula corymbosa, Melosira juergensii, Cyclotella spp., Thalassiosira spp. etc., while the main microalgae larger than 20 micrometers were Coscinodiscus jonesianus, Grammatophora marina, Achnanthes brevipes and Odontella obtusa and the like.
