Community Structure and Health Assessment of Macrobenthic Assemblages at Spring and Summer in Garorim Bay, West Coast of Korea

Macrobenthos community on the intertidal at Garolim Bay in summer

“…The ratios of total organic carbon and total nitrogen in the surface layer sediment of intertidal at Garolim Bay appeared very low with average ratio of 0.34% and 0.02%, respectively, except for the places in the near by Cheongsan-ri southwestward from the bay and in the area of tidal flat of Seosan-si eastward from the bay which were commonly distant from the water channel placed in the center of the bay showing relatively higher ratios thereof. As stated by Jung et al (2014a) et al, 2014b). In particular, the level of habitation density and biomass of macrobenthos appeared significantly lower than the results obtained from the study conducted by Shin et al (2004) (Table 6).…”

“…Besides, the total organic carbon, silt and clay were found negatively correlated with the average grain size; and positively correlated with sand. The correlation was identified through relatively higher frequency of appearance and habitation density of two species of H. filiformis and M. californiensis commonly found from the area employed in previous studies Wi, 2008;Jung et al, 2014a). Seo and Hong previously suggested that two species should preferably be taken rather as opportunistic species to be classified into the ones of indicator species of contamination (Seo and Hong, 2004).…”

“…Several previous studies described the macrobenthos distribution pattern and inhabit in the Garolim Bay (Lee et al, 1983;Shin et al, 2004;Jung et al, 2014a), and Kim investigated the growth, mortality and production of Tapes philippinarum in Garolim Bay (Kim, 1986).…”
