摘要

Seasonal variation of the fishery resource in the shallow waters of Ganghwado tidal flat was investigated using monthly collected samples with a fence net from June 1998 to May 1999. Thirty-six species were found, including 27 fish species, 6 crustaceans, and 3 molluscs. Of the fish, Konosirus punctatus, Sardinella zunasi, Liza haematocheila and Synechogobius hasta dominated in the number of individuals (92.1%) and in biomass (94.5%). A few number of resident species, such as L. haematocheila and S.hasta, were collected only during the cold months. As the water temperature increased in the spring, the adult migratory fish, such as K. punctatus and S. zunasi, were collected. Tn the summer, the juvenile fish recruited in the shallow water showing apeak in fish abundance. The data suggested that they grew until late autumn before moving to deeper waters for over-wintering. The principal component analysis showed that the seasonal variation in species composition was principally determined by watertemperature and/or water temperature related factors. The species composition of the fish assemblage in the study area suggested that these species are highly adapted to extreme seasonal temperature variation and high water turbidity.
