Abstract
Surface and bottom sea water samples were harvested from the 5 stations inthe marine ranching ground of Tongyeong coastal water from year 2000 to 2002. Cellnumber of heterotrophic bacteria was determined by using the plate counting methodto explore the variation of the cell population of heterotrophic bacteria. Sea watersamples collected in summer (in July and August) contained much larger number ofheterotrophic bacteria than those harvested in spring, autumn and winter. Hetero-trophic bacteria were usually more abundant in surface sea than in bottom sea water.However the reverse was true for sea water collected in December 2001 and February2002 due to suspended solids accumulating more abundantly in seabed area because ofthe slower convective current of the sea water in winter. Number of heterotrophicbacteria did not have a strong relationship with frequency of typhoon indicating thatthe path and powerfulness of the typhoon, localized torrential downpour andtemperature variation accompanying the typhoon should be considered all together atthe same time as well as the frequency of typhoon to explain clearly the variation ofcell number of heterotrophic bacteria. The dominant species isolated from the marineranching ground of Tongyeong were identified to be Pseudomonas fluorescens,Pseudomonas stutzeri, Acinetobacter lwoffii and Sphingomonas paucimobilis .
