  • For the hygienic production of oyster at Goseong bay, this study investigated the marine bacteriological condition of the area from 2008 to April 2009. Average seawater temperature and salinity ranged $2.8-19.3.0^{\circ}C$ and 32.61-34.91 psu, respectively. The coliform group and fecal coliform of seawater ranged < 1.8-4,900 MPN/100 mL and < 1.8-700 MPN/100 mL, respectively. The coliform group of oyster (Crassostrea gigas) ranged < 1.8-13,000 MPN/100 g. Fecal coliform of oyster ranged and < 1.8-310 MPN/100 g. Only one of 140 samples was exceeded in the U.S NSSP standard (> 230 MPN/100 g) of fecal coliform. Fecal coliform in seawater was on the level of clean sea, below the U.S. NSSP standards, and the contents of fecal coliform and heavy metals in cultured oyster were also below the U.S. NSSP, heavy metal standards, showing that the sea area is bacteriologically safe.

  • Two cellular biomarker parameters of the farmed Pacific oyster Crassostrea gigas were studied in vivo and in vitro after exposure to concentrations of polychlorinated biphenyls in terms of neural red uptake (NRU) and lysozyme activity. The oysters exposed in vivo to the xenobiotic concentrations, 0, 30, 90, and 180 ng/g for 14 days, enhanced hemocyte NRU with occasional significant differences (P<0.05), depending on the chemical concentration and duration. An adverse tendency was manifest in the lysozyme activities both in the hemocyte and serum of the oyster treated with the chemical in a same manner, rendering these two cellular parameters as biomarker candidates against the chemical. The oysters exposed in vitro to the chemical concentrations, 0, 1, 5, 10, 100, 1,000, and 10,000 ng/g for 24 hrs at $10^{\circ}C$ showed a similar tendancy as those exposed in vivo to the chemical. Unlike in vivo response, however, the in vitro NRU was first influenced by very low concentration of the chemical. In in vitro results, marked but not significant increase of hemocyte NRU was noticed at the chemical concentration of 5 ng/g, where the value was almost as high as those exposed to higher chemical concentrations, up to 10,000 ng/g. An unusual result was observed in the in vitro lysozyme activity of hemocyte in which significant decrease was first noticed at the chemical concentration of 100 ng/g.
