To understand the characteristics of community of demersal fishes in north Tung-Sha Tao, 6 bottom trawl operations were conducted along a transect at depths of 280-361 meters during 17-18 April 1995. A total of 11 major fish species occupying 69.4% of the total collected species were recorded. Three prawn species, Heterocarpus woodmasoni, Haliporoides sibogae , and Plesionika spp. were found. The species that was found at duplicated stations and with a total linear biomass greater than 20.0 were selected for the cluster analysis. The relationship between the values of Shannon-Wiener's index and the sampling stations had no significant difference (p>0.05). Using the Unweighted Pair Group Method Arithmetic Average (UPGMA) and the Bray-Curtis dissimilarity values, the 11 fish species were classified into 2 groups and 6 trawls were grouped into 2 clusters respectively.
