“…Some biotic indices were calculated simplely using only macrobenthic fauna data for assessing the community health conditions. Examples are AMBI (AZTI's Marine Biotic Index) [27] and BPI (Benthic Pollution Index) [7][8][9]. The theoretical basis of BPI was from the ITI (infaunal trophic index) proposed by Word [28].…”

“…Thus BPI is 0 when all fauna are composed of opportunistic or pollution indicative species, while BPI is 100 when all fauna are carnivores or filter feeders. Choi and Seo [8] and Seo et al [9] suggested that the threshold value of healthy conditions of BPI can be set as 60. They also classified the degree of health into five different stages using this threshold index value.…”

This study was conducted to get some basic information on the community structure of macrozoobenthos and its temporal change at 3 sites on the Gapo artificial tidal flat within Masan Bay from March 2002 to April 2004 when 8 years passed after the construction. The Gapo artificial tidal flat was constructed by filling the dredged contaminated sediments of Masan Bay from 1990 to 1993. The surface sediment consisted of fine particles, but the grain size at the tidal flat has changed from mud to muddy sand by adding coarse particles for manila clam aquaculture by local fishermen from 2002. A total of 35 faunal species including 23 species at the upper tidal flat, 28 species at the lower tidal flat and 30 species in the tidal channel were collected during the study period. Polychaete worms were the most dominant fauna in species number and total faunal density, but mollusks were the most dominant in biomass. There was a specific species composition along tidal level. At the upper tidal flat, Prionospio japonicus, Sigambra tentaculata, and Neanthes succinea were dominant and at the lower tidal flat, N. succinea, P. japonicus, Corophium sinensis, and Ruditapes philipinarum were dominant while S. tentaculata, Paraprionospio coora, and C. sinensis were dominant at the tidal channel. In the feeding guild composition of the community, the surface deposit feeder (SDF) was the most abundant functional group followed by carnivores. The abundance and biomass showed a seasonal fluctuation; they decreased during summer seasonal and recovered in autumn. The Benthic Pollution Index (BPI) reflecting the trophic composition of macrozoobenthic community at each site remained in a very low level during most study period, which indicates the macrobenthic community of the Gapo artificial tidal flat has been in a disturbed environmental condition. The MDS plots also indicated that the species composition has changed seasonally and a large change in it was shown from spring to summer at all three stations. These results indicated that the benthic community in the constructed mud flat area has not reached on a stable structure until the spring of 2004 for 10 years after the artificial tidal flat construction.

This study was performed to investigate the community structure and health assessment of macrobenthic assemblages in Cheonsu Bay, West Coast of Korea. Total species number was 224 and mean density was 1,940 ind./m ) and the amphipod Eriopisella sechellensis (167±100 ind./m 2 ). As a result of community statistics (cluster analysis and nMDS ordination), the macrobenthic community structure was classified two major groups (inner and mouth of bay) and two stations (station 2 near Ganwol dyke in spring and summer). The Benthic Pollution Index (BPI) and AZTI's Marine Biotic Index (AMBI) were applied to assess the benthic ecological status. During the sampling periods, the BPI Index values varied between 11 (bad status) and 92 (high status). On the other hand, the AMBI Index values was ranged between 1.34 (good status) and 4.39 (poor sta-

. Polychaetes was the richest and most abundant faunal group that comprised 37% in both total species number and density whereas echinoderms were biomass-dominant faunal group that accounted for 44% of the mean biomass. There was a seasonal variation in the species richness and abundance of macrobenthos with more species in winter and higher density in spring. Mean faunal density was relatively high at the stations near Namhaedo Island, but gradually decreased toward offshore stations. The most dominant species in terms of density was an amphipod species, Eriopisella sechellensis which occurred as a top ranker during three seasons except spring recorded the fourth rank. E. sechellensis showed its high density at the near shore stations of Namhaedo Island, but this species did not occur around the entrance of Gwangyang
