This study was performed to investigate the geochemical and benthic environment of three shellfish farms in Suncheon Bayduring the period of September 2014 ~ April 2015. Three sampling stations were selected; St.1 is the shellfish farm of razorclam near Jangsan area. St.2 is the shellfish farm of small ark shell near Hwapo area and St.3 is the shellfish farm of razorclam near Yongdu area. Razor clam was the dominant species at St.1, small ark shell and granulated ark shell were dominantat St.2 and St.3, respectively. Granulated ark shell inhabited St.3, although it is not cultured at that station. This station’sexposure to air during the ebb tide and sediment composition likely provides the appropriate habitat for granulated ark shellspecies. Analysis of the number of different species showed that 8 benthos species were found to be distributed at St.1, 18species at St.2, and 13 species at St.3. Among three stations, the highest Ignition Loss (IL), Chemical Oxygen Demand (COD)and Acid Volatile Sulfide (AVS) values were obtained from the sediment at St.2. The analysis of pore water from St.2 alsoshowed the highest values of Total Organic Carbon (TOC), ammonia (NH4+), Dissolved Inorganic Nitrogen (DIN) andphosphate (PO43-). These results are related to the fact that species dominance and richness is the highest in St.2. |
