Abstract

Effect of night-lights on zooplankton attraction has been studied in Tongyeong marine ranch area during the period from 12 July to 30 August, 2004. Each sampling has been carried out to collect zooplankton from both control area in natural waters experiment area of night-lights waters at night. A total of 43 taxa of zooplankton occurred during the study. Copepods showed the prosperity in species number with 15 species. Acartia erythraed and Copepodite occurred abundantly in night-lights waters. Zooplankton abundance appeared to increase in night-lights mainly due to the gathering of copepods and larvae through the study period. Average $3\sim166$ times of zooplankton abundance was recorded in night-lights when compared with that in control area of natural waters due to the gathering of copepods and larvae. Cluster analysis, based on monthly abundance data of the 13 most frequent species, showed that the species were seperated into two different groups: the photo-positive group and the photo-negative group.

점등 효과에 따른 동물플랑크톤 군집동태의 변화를 관찰하기 위하여 통영 바다목장 해역내 한국해양연구원 가두리 설치 지역에서 2004년 7월부터 2004년 8월까지 채집을 실시하였다. 점등 효과를 알아보기 위한 시료 채집은 야간에 점등구간에서 또한 자연상태의 동물플랑크톤 군집과 비교분석을 위하여 같은 시간에 인접 지역에서 점등에 영향을 받지 않는 장소를 선정하여 점등 시료와 동일한 방법으로 채집하여 비교 분석하였다. 조사기간 중 출현한 동물플랑크톤은 종 수준까지 동정한 21종을 포함하여 총 43개 분류군이었다. 불을 밝힌 점등구에서의 출현 분류군수는 비점등구에 비해 많은 개체수가 나타났으며, 두 구간에서의 동물플랑크톤 평균 출현량에서도 비점등구에 비해 점등구에서 약 $3\sim166$배 높은 출현량을 나타내었다. 본 연구에서 점등(불빛)으로 유집되는 동물플랑크톤 군집의 반응양상은 2개로 대별하여 특정지을 수 있는 것으로 나타났다. "A"그룹은 조사시기별 높은 출현 빈도를 나타낸 종들로 불빛에 명확한 양주광성(photo-positive)종들로 구성됨을 알 수 있었다. "B"그룹에 속하는 종들은 약간의 차이는 있으나, 대부분이 점등(불빛)에 소극적으로 반응하는 음주광성(photo-negative)으로 나타났다.
