dc.description.abstractA fish pond ecosystem on the west coast of Korea was studied for biotic and abiotic factors. The occurrence rate of phytoplankton at the embanked fish farm was 84 times higher to that of shore waters. Phytoplankton species which occurred during the study period were categorized into Cyanophyta, Dinophyta and Bacillariophyta with a total of 26 subgeneric taxa (22 species of Dinophyta, 2 species of Bacillariophyta and 2 species of Cyanophyta). The total cell density during the study period ranged from16 x 103 to 13.59 x 10(5) cells l(-1). As for the zooplankton, the monthly density ranged from 26 - 8.684 x 10(3) cells m(-3) with an average of 126.0 x 10(3) cells m(-3) for April. In the case of May, it ranged from 41 - 3.331 x 10(3) cells m(-3) and its average of 50.3 x 10(3) cells m(-3) which was comparatively less. The varying environmental factors in Seosan embankment A, B and Chonsu Bay waters could have affected the fish farm. According to the results, the concentration of inorganic nitrogen was 0.067-0.106 (average: 0.083) mg l(-1) and the concentration of organic nitrogen was 0.008-0.022 (average: 0.014) mgl(-1). Also due to the release of brackish water at Seosan embankment A and B, the inorganic nitrogen showed an increasing trend. The survival rate of Sabastes schlegeli, and Acanthopagrus schlegeli was high in stations 2H and I (20.87%, 33%) and relatively low in stations 2B to 2F.en_US
