中文摘要 | 本文針對池堰式魚道中臺灣石�a之溯游行為分區進行探討。 本研究以無線電量測 系統監測魚隻在魚道中溯游之軌跡,並利用此資料分析魚隻在魚道溯游過程中泳速及加速度 之變化,並根據魚隻泳速及加速度之大小進行運動型態之分類,進而統計魚隻在魚道各位置 上出現各種運動型態之次數,繪製魚道運動型態分區圖,最後將各組實驗之運動型態分區圖 重疊合併而得到魚隻朔游行為分區圖。 研究結果顯示池堰式魚道水池可區分為 (1) 減速→ 休息區, (2) 休息→加速區及 (3) 加速→減速區等三個溯游行為區,其中第一及第三分區 亦為魚隻處於高速狀態之區域。採用本研究發展之方法分析所得之溯游行為分區具有相當之 聯貫性與一致性,充分反映臺灣石�a在池堰式魚道中之溯游行為模式,可供後續魚道設計之 參考。 |
英文摘要 | This paper investigates the zoning of pool-weir type fishway by upstream migration behaviors of Acrossocheilus Formosanus. This study uses telemetry system for monitoring fishery migration in the fishway. The recorded data are used to analyze the swimming speed and acceleration of the fish. Based on the magnitudes of swimming speed and acceleration, the upstream migration patterns can be categorized. Theoccurrence frequencies of various migration patterns are evaluated at the corresponding locations of the fishway, and the zones of varius migration patterns are plotted along the fishway. These plots are overlapped for zoning of the upstream migration behaviors. The results reveal that the pool of the fishway can be divide into three zones, namely: (1) decelerating-to-resting zone, (2) resting-to-accelerating zone, and (3) accelerating-to-decelerating zone, of which the first and the third are also categorized as high-speed zone. The proposed methodology results in a continuous and consistent zoning that sufficiently reflects the upstream migration behaviors of Acrossocheilus Formosanus in the pool-weir type fishway. The results of the present study provide guidelines for future fishway design. |
