Abstract: The phytoplankton and ambient environmental parameters were monitored in the scallop aquaculture area near Zhangzi Island in the northern Yellow Sea during twelve monthly surveys from 2011 to 2012 to evaluate the annual characteristics of phytoplankton community in the scallop aquaculture area near Zhangzi Island in the northern Yellow Sea.Uterm?hl analyzing method with an inverted microscope revealed that a total of 119 species（53 genera）were recorded from the samples collected.Phytoplankton communities were characterized by dominant species in Pyrrophyta and Chrysophyta in summer and autumn，and Bacillariophyta，Euglenophyta and Pyrrophyta in winter and spring，with monthly cell abundance from 17×103cells/L to 312×103cells/L，annual averaged 77×103cells/L.Two peaks of the cell abundance were observed in spring（March and April）and autumn（Septemper and October），with high species diversity in autumn.Dominant species throughout the whole year were diatoms including Paralia sulcata，Guinardia delicatula and Thalassiosira pacifica，and Ceratium fusus，Dictyocha fibula and Eutreptiella gymnastica were the predominant species in summer，autumn and spring，respectively.Canonical correspondence analysis and redundancy analysis between cell abundance and the ambient environmental factors showed that seawater temperature and dissolved oxygen level were the key factors in driving the annual pattern of phytoplankton variation.Dissolved inorganic nitrogen and phosphorus were as well responsible for the distribution of phytoplankton cell abundance and succession of dominant taxa in the study area.Considering abundant food species of natural phytoplankton，the adjoining waters near Zhangzi Island were fertile regions for growth and sustainable mariculture of scallops.Taxa such as P.sulcata，T.pacifica and C.fusus could be the suitable phytoplankton indicators for local fisheries.
