| Present study aims to investigate the effect of muddy water on the gill and the kidney tissues of Zacco koreanus under high turbidity rearing condition. The gill of Z. koreanus showed abnormal shapes in its secondary lamellae and a rough surface with impure debris in the high level of turbidity and the longer raising period condition. In addition, the gills showed the edema, the exfoliation of epithelial cell, and the fusion of the secondary lamellae. In case of kidney tissue, the atrophied glomerulus was observed, and the empty space in Bowman's capsule was wider. The SOD activities in both gill and kidney tissues were increased in proportion to the high level of turbidity. On the while, CAT and GPX activities were shown constant level in the gill, but were increased in the kidney in the high turbid muddy water. These results indicate that the harmful radicals which generate by high level of turbidity could be removed partly by antioxidant enzymes in the kidney. The concentrations of micro heavy metal ions accumulated in the gill increased drastically at the 1,000 NTU. Based on the above results, it is considered that the exposure to the high level of turbidity for long period may affect on the structures of tissues, and change the enzymatic balance in Z. koreanus, causing the fatal disease. |
