During
July 2015 to June 2016, two permanent sampling sites were established in Scirpus mariqueter salt marsh and its adjacent mudflat on the intertidal
zone of Chongming-Dongtan in the Yangtze Estuary. Based on monthly trap net surveys
of fishes, the characteristics of the fish assemblages in the different
subhabitats, including the salt marsh and mudflat, and the monthly variations
were analyzed. A
total of 19 species of fishes were found belong to 12 Families. The characteristics including the
dominant fish species were different in these two subhabitats. 18 species of fish
were recorded in the mudflat, of which the dominant species were the Coilia ectenes, Pelteobagrus nitidus and Lateolabrax
maculatus. Ten species of fish were recorded in the salt marsh of which the
dominant species were the Coilia ectenes, Saurogobio dumerili, Liza haematocheila, Lateolabrax maculatus and Acanthogobius
ommaturus. Pelteobagrus nitidus prefers to use
the mudflat, while Lateolabrax maculatus and Liza haematocheila
