Abstract
The benthos were studied based on three surveys in 10 stations in the waters of Dalian coast from Docter, 1997 to July, 1998. The results showed that 79 species of benthos were indentified, 42 species of which are polychaeta, 23 mullusca, 7 arthropoda, 3 echinodermata, 2 tunicata and 2 other animals. The average density and biomass (wet weight) of benthos was 4663.3 ind./m 2 and 740.5 g/m 2 . The analysis based on the resuls showed that the waters of Dalian coast have been polluted lightly or moderately.
