中文摘要 | 本研究從1996年7月至1999年6月以三年間調查埔里中華爬岩鰍在台灣之分布及其與棲地環境的關係,發現於台灣西部的高屏溪、曾文溪、濁水溪、烏溪及大甲溪等流域海拔25-340m有埔里中華爬岩鰍分布之河段,流速、底質、導電度和海拔高度為影響埔里中華爬岩鰍單位努力捕獲量(catch per unit effort, CPUE )和分布的最重要環境因子,根據資料顯示,其偏好的環境條件中最適合流速為1.0 m/s,導電度為366 μmhos/cm,水深為38 cm,底質為卵石(直徑7.7-30.5 cm)。 |
英文摘要 | Distribution and environmental requirements of Sinogastromyzon puliensis, an endemic species of fish in Taiwan, were investigated from July 1996 to June 1999. The fish were found in the Kaoping, Tsengwen, Choshui, Wu and Tachia rivers in the western portion of Taiwan at altitudes from 25m to 340 m. Velocity, substrate, conductivity and altitude were the important environmental factors affecting the population density (catch per unit effort, CPUE) and the distribution. The preferred habitats of the fish were at velocity of 1.0 m/s, conductivity of 366 μmhos/cm, water depth of 38 cm, and substrate of 7.7-30.5cm in diameter. |
