This study is performed to clarify the fish fauna and fish habitat of downstream of Singok submerged weir within Han River estuary during April~December 2009. It was studied at the nine sites of Han River estuary area. The three of them were located in the mainstream of Han River and six of them were located in three wetlands which as Sannam, Janghang and Dolbangguji. Total fish fauna was identified as 9 order 15 family and 38 species (2,230 individuals). It was divided as 8 order 11 family 28 species from three sites in the mainstream of Han River and as 5 order 8 family 19 species in waterways at mud flats of three wetlands. It was made up the fish fauna as 3 order 4 family 12 species during the survey period at the waterways in the rice paddies. Hemibarbus labeo was dominant species in the whole research sites and waterways at mud flats. Carassius auratus was dominant species in the waterways between rice paddies and Chelon haematocheilus was dominant species in mainstream of Han River estuary.

The seasonal variation of phytoplankton communities and its standing crops in accordance with environmental factors were investigated at Yeongrang-ho, Cheongcho-ho, Mae-ho and Hyang-ho which are located in the East coast of Korea during April to October 2011. High concentrations of T-N and T-P were observed in four lagoons due to the inflowing nutrients from farmlands and residential areas near lagoons. Nutrient salts mainly composed of nitrogen and phosphate caused the eutrophication of the lakes, leading to the robust growth of phytoplankton. During the period of investigation, 64 to 107 taxa of phytoplankton were observed in four lagoons. Diatoms were the most dominant species with high density. Non-point pollution source was estimated as the main cause of water pollution of lagoons. Trophic states of lagoons evaluated using the value of TSI and TSIKO indicated that all the investigated lagoons were in the eutrophication state.

Phototrophic bacteria T-20 investigated in the present report was isolated from Thailand oil, Cells of the bacterium were rod-shaped. measured 0.6∼0.7㎛ wide, and 2.3㎛ long. A color of cell suspension was red, and the long wavelength absorption maxima of the bacteriochlorophyll measured in 870㎚. Substrates utilized as carbon sources: citrate, aspirate, glutamate, and fructose: unique for this strain is the liquefaction of gelatine, Ubiquinone Q-8 was also found. Rhodocyclus gelatinosus, which was reported in Bergey's Manual of Systematics Bacteriology, was corresponded to T-20.
