魚菜共生栽培系統研發之先導計畫

本研究應用 Arduino 單晶片於魚菜共生系統中的水位控制，有別於現今台灣一般家庭式之水位控制，確實可透過程式撰寫與控制元件的結合，即可控制系統中的水流狀況，而不需改變初始的系統設備配置。 以室內人工光源之全循環模式進行養殖試驗，種植出的小白菜平均鮮重約13g、平均葉長約 20cm，其硝酸鹽含量約在 4,000ppm；吳郭魚飼料換肉率可達2.30。以室內養殖之魚菜共生系統為例，在系統中有充足的硝化作用，每日飼料餵食量為魚體總重 1~3%，吳郭魚與小白菜之間的養殖比例，一株小白菜（鮮重13.0g）可對應吳郭魚 4.1~5.6g。

This study apply Arduino to the water level control of aquaponics systems, unlike Taiwan general family of level control nowadays. It can control the flow of this system without changing the initial equipment setting by program and control element. The experiment selected complete cycle model and used artificial light in room. Getting the plant of bok-choy, its average fresh weight about 13g, average leaf length about 20cm, its nitrate content about 4,000ppm. The mash exchange rate of tilapia is 2.30. Taking indoor aquaponics systems for example, in the condition of the system has full nitrification, the mash quantity is 1~3% of the fish weight a day, the proportion of tilapia and bok-choy is that one bok-choy(fresh weight:13g) correspond to tilapia weight: 4.1~5.6g.
