魚菜共生系統之原理與應用方法
The Principle and Application Method of Aquaponics System
摘要
近年來透過水產養殖和農耕結合之魚菜共生的概念，正慢慢延伸到世界的各個角落。許多人紛紛在大廈的屋頂、客廳角落及居家的陽台設立靠著養魚水灌溉植物的生態系統。既能營造宜人景觀，也能提供家庭新鮮、衛生的蔬果。魚菜共生系統其原理係將養殖物排放至水中的排廢物經硝化作用後由作物吸收。藉由作物將水淨化後再回收當做新的養殖用水，因而提高了水的利用效率。本研究建置兩種不同型式的魚菜共生系統進行試驗，結果顯示養殖水可提供作物生長所需的養份，但會有微量元素缺乏的問題，而透過適量補充就能讓作物正常生長，作物能淨化水質讓養殖水得以能不斷的循環利用。因此如能控制合適的放養密度，適量的投餌餵食並配合季節選擇作物，以及適時適量的補充作物所需的養分，則此系統實為一種能同時達到節能、省水、省肥的生產系統。

In recent years, aquaculture and farming combined with the concept of acquaponics, it is gradually extending to every corner of the world. Many people in the building's roof, living room corner and home of the balcony, set up relying on fish water irrigation plants of the ecosystem. Not only to create a pleasant landscape, but also to provide fresh, healthy fruits and vegetables. The principle of the acquaponics system is the fish waste that is discharged into the water and is absorbed by the crop after nitrification. The water is purified by the crop and then recovered as fresh aquaculture water, thus improving the water use efficiency. In this study, two different types of acquaponics system were designed, the results show that aquaculture water can provide the nutrients needed for crop growth, but there will be a shortage of microelements, by appropriate supplement can make the crop normal growth, and crops can purify the water so that aquaculture water can be recycled. So as long as the control of the appropriate stocking density, the amount of feeding and with the season to select crops, as well as the right amount of nutrients needed to replenish the crop, this system can be regarded as a production system that can achieve energy saving, water saving and provincial fertilizer at the same time.
