초록

본 연구는 충남 예산군 대흥면과 응봉면 사이에 위치한 예당호에서 2013년, 2014년과 2017년에 어류군집 특성 분석을 위해, 조사기간 동안 3개 조사지점에서 출현한 어종은 총 10과 29종이었다. 잉어과(Cyprinidae)에 속하는 종이 34.5%로 가장 다양하게 나타났고, 동자개과와 망둑어과가 10.3%, 미꾸리과 검정우럭과가 6.9%로 나타났다. 한국고유종은 왜매치, 점줄종개, 눈동자개, 얼룩동사리 등 4종(13.8%)으로 낮은 비율이었다. 외래종은 떡붕어, 블루길, 배스 등 3종(10.3%)이었다. 군집분석 결과 우점도 지수는 0.45~1.00, 종다양도 지수는 0.19~2.30, 균등도 지수는 0.41~1.94의 범위로 나타났다.

This study investigated the characteristics of fish communities at the Lake Yedang, in 2013 to 2014 and 2017. During the survey period, there were 29 species of 10 families collected from 3 survey stations. Of them, Cyprinidae occupied 34.5% (14 species), Bagridae, Gobiidae 10.3% (3 species), and Cobitidae, Centrachidae were 6.9% (2 species) in the number of species, respectively. Korean endemic species were 4 species (13.8%) Abbottina springeri, Cobitis nalbanti, Pseudobagrus koreanus, Odontobutis interrupta and accounted for a low rate. There were 3 species (10.3%) exotic species including Carassius cuvieri, Lepomis macrochirus, Micropterus salmoides. As a result of community analysis, dominant index was 0.45~1.00, diversity index was 0.19~2.30 and richness index was 0.41~1.94.
