초록

본 연구는 임하호에 서식하는 잉어목(Cypriniformes)의 강준치(E. erythropterus), 누치 (H. labeo), 피리미 (Z. platypus)와 메기목(Siluriformes)의 메기(5. asotus), 농어목(Perciformes)의 쏘가리(S. scherzeri)를 이용하여 탁수가 어류에 미치는 영향을 비교 조사하였다. 탁수역에 서식하는 잉어목 어류의 아가미 조직은 메기목이나 농어목 어류보다 이차새변 간격이 불규칙 하였고 이차새변의 만곡이 두드러졌으며, 부종과 상피세포의 분리도 매우 높은 빈도를 나타냈다. 그러나 곤봉화는 농어목과 메기목에서 높은 빈도를 보였으며, 새변 사이에 부착되어 있는 이물질과 미세입자는 농어목과 잉어목에서 높은 빈도를 나타냈다. 또한 신장 조직내 사구체의 수축은 잉어목의 피라미에서 훨씬 많이 나타났다. 이러한 결과로 보아 잉어목의 어류가 탁수에 의해 가장 두드러지게 영향을 받고 있다. 탁수에 의한 혈액 성분의 변화는 잉어목에서 IP, ALB의 함량, A/G비, TG 및 CHOL의 함량이 높았고, 메기목에서는 무기질의 함량이 높았다. 또한 잉어목에서 ALT와 AST의 활성이 높았으며 상대적으로 AST 활성이 ALT의 활성 보다 높았다. 이러한 혈장 성분의 변화는 탁수로 인해 먹이 탐식 능력이 저하되고 이로 인해 섭이 상태가 좋지 못하거나 조직의 손상 등에 기인한 것으로 생각된다.

In the present study, the effects of muddy water were compared and examined on the fish inhabiting Imha reservoir, E. erythropterus, H. labeo and Z. platypus in Cypriniformes, S. asotus in Siluriformes and S. scherzeri in Perciformes. In the gills of fish in muddy water, the secondary lamellae of fish in Cypriniformes showed more irregular gaps and more winding than those in Siluriformes and Perciformes. Also, the edema and detachment of epithelial cells was more detected in the gills in Cypriniformes, but clubbing was frequently detected in Perciformes and Siluriformes. Also, we found that muddy debris and minute particles attached to lamellae were frequently detected in Perciformes and Cypriniformes. The glomerulus in the kidney was much more constricted in Z. platypus in Cypriniformes. As a result, it is proposed that fish in Cypriniformes are more affected by muddy water. In the changes of blood components, which might be affected by muddy water, the concentrations of TP, ALB, TG, CHOL and A/G ratio, were high in Cypriniformes, and inorganic matters were abundant in Siluriformes. In addition, AST activity was relatively higher than ALT and both activities were higher in Cypriniformes than in Siluriformes. Taken together, the change in blood plasma may be caused by the reduction in voracity in the wake of muddy water, which results in tissue damage.
