中文摘要 | 天然環境下魚類大量出現脊柱畸形的現象並不常見。然而自從1993年起,每年夏天在台灣北部第二核能發電廠之溫排水口水域,皆可發現為數不少的畸形花身雞魚。本研究利用X光成像及透明骨骼染色法,解析在此水域中釣獲的花身雞魚之畸形率及其畸形模式。結果顯示,1994年出水口整建前後的畸形魚出現率,自88.7%顯著地下降至10.8%。畸形魚脊柱的彎曲可分為三種上下彎曲的類型,其比例分別為單峰型34.9%、雙峰型63.5%及三峰型1.6%。脊柱彎曲的嚴重程度與魚體長無關,顯示在此水域中任何體長的花身雞魚都可能發生畸形。 |
英文摘要 | Massive occurrences of vertebral deformities of fish are not commonly found in the natural environment. However, a great number of deformed thornfish, Terapon jarbua, have been routinely found every summer since 1993 in the thermal effluent outlet of the second nuclear power plant (NPP II) in northern Taiwan. The quantitative prevalence and patterns in deformity of thornfish angled in the outlet water were roentgenogram and bone double-staining examined. The prevalence of malformation decreased dramatically from 88.7% to 10.8% after outlet reconstruction in 1994. Spinal curvature of the fish could be classified into three lordosis types (single-, double- and triple-peak), accounting for 34.9%, 63.5% and 1.6%, respectively, of total deformed individuals. Severities of the spinal curvatures were not correlated with fish length, indicating that the deformity may occur at any fish length in the outlet water. |
