초록

2005년 5월부터 2006년 3월까지 6회에 걸쳐 안동호에 서식하는 주요어종의 어류상과 길이-무게 상관관계를 조사한 결과는 다음과 같다. 본 조사에서 확인된 어류는 총 7과 20종2540개체였으며, 우점종은 누치 (Hemibarbus labeo, 19.6%), 아우점종은 떡붕어(Carassius cuvieri, 19.2%)로 나타났다. 한국고유종은 치리(Hemiculter eigenmanni, 7.1%), 참몰개(Squalidus chankaensis tsuchigae, 0.1%), 꺽지 (Coreoperca herzi, 0.1%) 등 3종, 외래어종은 떡붕어(Carassius cuvieri, 19.21%), 블루길(Lepomis macrochirus,4.2%), 베스(Micropterus salmoides, 0.2%)3종으로 나타났으며, 우점도는 0.388, 종다양도 3.159, 종풍부도 2.423, 균등도는 0.730이었다. 주요 출현어종 9종에 대한길이-무게 상관관계식에서 피라미(Zacco platypus, 3.2509, $R^{2}$= 0.9928)가 가장 높은 성장도를 나타냈으며, 누치(H. labeo, 2.9162, $R^{2}$ = 0.9567)가 가장 낯은 성장도를 나타냈다. 각 어종에 패한 비대지수에서는 누치( H. labeo)와 잉어(Cyprinus carpio)를 제외한 7개 어종에서 기울기가 양의 값으로 나타나 건강상태가 비교적 양호한 것으로 확인되었다. 각 어종에 대한 길이-무게 상관관계에서 매개변수 b의 값의 평균은 3.1079로 성장상태가 매우 양호한 것으로 확인되었다.

The fish fauna and weight-length relationship in Andong reservoir were investigated from May 2005 to March 2006. During surveyed period, 2,540 individuals 20 species belonging to 7 families were collected. Dominant species were Hemibarbus labeo(19.6%) and sub-dominant species were Carassius cuvieri (19.2%). The korea endemic species were Hemiculter eigenmanni(7.1%), Squalidus chankaensis tsuchigae (0.1 %), Corroperca herzi (0.1 %) and introduced fishes were Carassius cuvieri (19.21 %) Lepomis macrochirus (4.2%), Micropterus salmoides (0.2%). Dominace, species diversity, species richness, species even-ness were 0.39, 3.16, 2.42, 0.73 respectively. The values of the exponent b in the weight-length relation-ship $W=aL^{b}$ ranged from 2.9162(H. labeo, $R^{2}$=0.9567) to 3.2509(Zacco pla쇼pus, $R^{2}$=0.9928) and the median value was 3.1079, whereas 50% of the values ranged between about 3.05 to 3.20. The Condition factor(K) showed good state of health in the surveyed species (excepts H. labeo and Cyprinus carpio).
