| 中文摘要 | 在水產養殖環境中,氨不斷地被生產、消耗、及轉換,而且累積之後會具毒性,因此養殖場管理的目的就是儘量使氨含量低。本研究調查用絲蘭Yucca schidigera萃取物(YUPE)來降低淡水中氨的潛力及效率。我們以劑量-反應試驗用來決定YUPE在不同濃度0, 18, 36, 及72 mg/l對於總氨氮(TAN) 1, 3及5 mg/l的影響。效率分析顯示YUPE濃度愈高,TAN降低愈多。每段經過的時間內TAN的降低比率顯示在12-24時之間TAN減少量最高,在爾後每12小時的觀察中則下降,可能是因為YUPE效率逐漸耗盡。當與其他方法來比較YUPE降低氨的效率及安全性,以及其為天然物的本質來看,YUPE不失為淡水養殖水質管理-有潛力且值得推薦的候選物質。 |
| 英文摘要 | Ammonia is constantly produced, consumed and transformed in aquaculture environments, and can be toxic if allowed to accumulate; hence, the goal of farm managers is to keep it at a minimum in their facilities. This study investigates the potential and efficacy of Yucca schidigera extract (YUPE) for ammonia reduction in freshwater. A dose-response experiment was conducted to determine the effect of different concentrations of YUPE at 0, 18, 36 and 72 mg/l on total ammonia nitrogen (TAN) at 1, 3 and 5 mg/l. The efficacy analysis showed that at higher YUPE concentrations, higher TAN reduction was observed. Likewise, an increase in elapsed time also increased TAN reduction. The fraction of reduced TAN at each elapsed time showed that TAN reduction was highest during 12-24 h, and decreased thereafter at 12-h interval presumably due to exhaustion of YUPE’s efficacy. The efficacy and safety of YUPE for ammonia reduction when compared to other methods, and its natural origin, make YUPE a potential and recommendable candidate for water quality management in freshwater aquaculture. |
