本試驗目的在提升魚菜共生系統中氮利用率。以吳郭魚搭配作物之魚菜共生系統為 雛型，利用系統中培養生物絮團來養殖經濟價值較高的觀賞蝦類，包括設計培養生 物膠羽與觀賞蝦的養殖空間，規畫操作的收獲方式，評估生物絮團及相關生產效能 ，藉由系統增加觀賞蝦養殖來提升系統氮的利用。本系統規格如下:系統總水量 1000L；養殖水量500L；養殖魚吳郭魚 養殖重量20公斤；種植萵苣； 時間30天 ；Biofloc桶120L ；玫瑰蝦養殖桶70x45x40 cm 3 塑膠黑桶 (136L) ；吊掛不織布 40x30 cm 26片；可蓄養玫瑰蝦成蝦1800尾。生物絮團試驗結果顯示: C/N比分別為 0、10、15、20、25的組別中，以C/N 25 有最佳的絮團生成量18 ml/L。在形成生物 絮團的組別中，水體氨氮、亞硝酸鹽、硝酸鹽量都相較於對照組低。此外，為簡化 魚菜共生系統系統的組裝，將系統進行模組化設計，完成模組化魚菜共生系兩型(室 外型、室內型)，這項技術對應用推廣有極大的助益。 本年度完成屋外型、室內型 兩款魚菜共生模組，並分別設置於口埤實驗國小及新化分院進行耐久試驗及情境試 驗。室內型系統著重於美觀及容易維護，室外型系統除提供生態景觀亦能實際進行 生產。試驗總計回收45份問卷資料，其中不同族群所回饋的意見亦有所差異。小學 生重視省水的特性，老師重視環境永續性，醫療院所人員則重視魚類生活狀態。主 要的外溢效應為魚菜共生模組具有實際的療癒作用，具有能夠舒緩壓力安定情緒的作用。

The purpose of this study is to increase the usage of nitrogen in the aquaponic system. Tilapia and lettuce were cultured in the system and Biofloc was cultivated to feed the ornamental shrimps. The system was extended with a Biofloc culture tank and an ornamental shrimp culture space. Biofloc formation was assessed in order to increase the usage of nitrogen in system. The aquaponic system is described as follows. The total water volume is 1500 L in which 500L water was set in the fish culture tank. The total fish weight is 20 Kg. Lettuce were cultivated for 30 days. The volume of Biofloc culture tank is 120 L and the volume ofNeocaridina sppculture tank is 136 L in which 6 pieces of nonwoven fabrics (40x30 cm 2 ) were set to host the shrimps. There are 1800 shrimps cultured in the tank. In Biofloc experiments, C/N25 has the most Biofloc formation(about 18 ml/L) among the groups C/N0, C/N10, C/N15, C/N20, and C/N25. The concentrations of ammonia, NO 2-and NO 3-in the Biofloc formed groups were lower than control. Additionally, the aquaponic systems were modularized in order to simplify the assembly process of the systems. We have completed two modular aquaponic sytmes which are indoor and outdoor. The modular techniques will facilitate the promotion of aquaponic systems.This year, the two types of aquaponic modules were completed, They were set up in theKoupi Experimental Elementary Schooland MOHW Tainan Hospital SIN-HUA Branch for endurance test and situational test. Indoor system focuses on aesthetics and easy maintenance, outdoor systems can actually be produced in addition to ecological landscapes. A total of 45 questionnaires were collected from the trial, and opinions from different ethnic groups were also different. Primary school students attach importance to the characteristics of water conservation, and teachers attach importance to environmental sustainability, Medical staff pay attention to the living conditions of fish. The main spillover effect is that the aquaponics module has an actual healing effect and has the effect of relieving stress and stability.
