Abstract

In the spring (March to June) in 2010, one diatom Skeletonema costatum occurred outbreaks in Lake Hwajinpo, one of the typical lagoons on the east coast of South Korea. We compared the characteristics of the phytoplankton community during the bloom and extinction period of S. costatum, and evaluated the water quality based on nutritional indices. Results indicate that 1) this bloom showed the highest cell density ($>10^5$ cells $mL^{-1}$) among outbreaks of S. costatum occurred Korea, 2) occurred in below or over $20^{\circ}C$ water temperature, and 3) was destroyed in the early summer with higher temperature than the bloom period. Water quality or trophic status of the lake was eutrophic to hypertrophic with high salinity, BOD, COD and phosphate, and low N/P ratios and transparency. Phytoplankton community in the spring bloom had a high dominance and low diversity, but rightly recovered to low dominance and high diversity in the summer season. Therefore, we temporarily conclude that the bloom of S. costatum in Hwajinpo was triggered by the extended spring drought and the reduced influx of river water, and appeal that the bloom can happen repeatedly every year.

한반도 동해안에 분포하는 대표적인 석호중의 하나인 화진포호에서 2010년 봄철(4~6월)에 돌말 Skeletonema costatum가 대발생하였다. 본 연구는 대발생기와 소멸기 동안 저수지의 식물플랑크톤 군집의 특성을 파악하고 수질을 근거로 하는 호수의 영양지수를 산출하여 수질을 평가하였다. 분석결과 국내에서 가장 높은 세포밀도($>10^5$ cells $mL^{-1}$)를 보였으며, 수온은 $20^{\circ}C$ 전후였으나 더 높았던 여름철(7월 이후)에는 소멸하였다. 저수지의 수질은 높은 염분도, BOD, COD, 인산염, 낮은 N/P비, 투명도 등으로 부영양~과영양 상태로 나타났다. 식물플랑크톤 군집은 돌말류가 높은 세포밀도를 보인 조류발생기 동안에는 높은 우점도와 낮은 다양도를 보였으며, 소멸기에는 다시 회복되는 특성을 나타냈다. 결국 2010년 화진포호의 Skeletonema costatum 대발생은 봄철 가뭄이 장기간 진행되고 하천수의 유입이 감소함으로써 비롯된 것으로 판단되며 매년 반복될 가능성을 시사해 주었다.
