翡翠水庫水質與魚類食性之關係研究

The Research of Relationship between Variations on Water Quality and Fish Feeding Habits in Feitsui Reservoir

指導教授 : 侯文祥

摘要


翡翠水庫自1987年啟用後為大台北地區公共用水的主要來源。翡翠水庫管理局除了建立長期的水質監測資料,自1988年起亦開始監測魚類及浮游生物資料,但非連續之魚類監測調查無法提供生物控制水質管理法有效的背景資料。因此本研究目的為調查近五年翡翠水庫魚類組成與其各自之食性變化,探討水域別與季節別之空間與時間變化差異對魚類食性之影響,進一步探討魚種食性變化與水質及浮游生物之關係,以提供翡翠水庫管理單位及本土集水區水質永續經營管理的本土化資料。 本研究調查翡翠水庫內魚類食性與浮游動物濃度,以浮游動物採集濃度、組成百分比;魚類攝食成分、組成百分比,配合捕獲時的水域水質資料,探討自2006年6月至2010年3月,累計15次的水庫水生生物相的調查。首先探討浮游動物與藻類在時間與空間的分布狀況,再分析水庫優勢魚種的食性隨水質之變化。最後將食性分析結果分別與總磷、葉綠素a、透明度、藻類個數等水質優養化因子進行相關性分析。 結果得知,原生動物在浮游動物中的百分比會隨著水溫升高而增加,其數量百分比與水溫之線性相關R2為0.51。藻類亦隨水溫升高而提高數目,2006年至2009年之月平均水溫與月平均藻類個數之線性相關R2為0.61。黑鰱與高身鲫隨著水溫越高攝藻率也越高,黑鰱與高身鲫的攝藻率與水溫之正相關R2分別為0.69與0.64。表示黑鰱與高身鲫可於水體藻類數增加時,經由攝食抑制藻類過度繁殖,改善水質透明度與葉綠素a濃度。 由調查結果顯示,翡翠水庫於夏秋季節不宜捕捉黑鰱與高身鯽兩種魚類,以抑制藻類生長。並應持續監測魚類組成的變化,以建立更詳盡的魚類與水質關係之基礎資料,提供水庫水質保全與永續管理之重要參考依據。

並列摘要


Feitsui Reservoir is a main source of the public water in Taipei since completing in 1987. Feitsui Reservoir Administration Bureau established a long-term water quality monitoring since 1988. It also started to monitor the fish and plankton, however, discontinuous monitoring investigation of the fish can not provide effective background data for biomanipulation. This research purpose is to probe into the relation that fish feeding habits change and water quality change, offering the Feitsui Reservoir Administration for biomanipulation management of water quality as the sustainable management of reference materials. This research investigates fish feeding habits and zooplankton concentration in the Feitsui Reservoir, probe into it from 2006.6~2010.3, total 15 times aquatics survey. Recording zooplankton and algae in the distribution of time and space, and then analysis fish of dominant species in reservoir water quality with changes in feeding habits. We discuss the relation between the variations of fish feeding habits in different water quality with analyzing the correlation, including the total phosphorus, chlorophyll-a, transparency and alga, etc. The results shows that protozoa in the percentage of zooplankton increases proportionally with the water temperature. The percentage of its number and water temperature of the linear regression R2 is 0.51. From 2006 to 2009 the monthly average water temperature and monthly average number of algae correlation R2 is 0.61. Aristichthys nobili and Carassius cuvieri promotes phytoplanktivorous rate when water temperature increases, the phytoplanktivorous rate and water temperature of the linear regression R2 is 0.69 and 0.64. Aristichthys nobili and Carassius cuvieri can improve water transparency and algal concentration. This research investigation shows that do not capture Aristichthys nobili and Carassius cuvieri when the summer and autumn in Feitsui Reservoir, in order to inhibit the growth of algae. We propose that the monitoring of variation in the condition of fish fauna should be carry out continually, and establish the continuous, correlative information between fish and water quality.
