A kind of tier rack type fish and vegetable symbiotic system includes one first aquatile culturing jar, one first plant cultivating pot, at least one second aquatile culturing jar and at least one second plant cultivating pot. This creation lower in a limited space can cultivate more aquatiles and the more plants of plantation by stacking the first aquatile culturing jar, first plant cultivating pot, the second aquatile culturing jar and second plant cultivating pot to create bigger economic benefit. In addition, this creation only must extract liquid using a drawing liquid part, and the circulation of liquid in the tier rack type fish and vegetable symbiotic system can be simply completed by one first siphon part, one second siphon part, an interval object, a drain part and an infusion part again.一種層架式魚菜共生系統，包含有一第一水生生物養殖缸、一第一植物栽種盆、至少一第二水生生物養殖缸以及至少一第二植物栽種盆。本創作藉由堆疊該第一水生生物養殖缸、該第一植物栽種盆、該第二水生生物養殖缸以及該第二植物栽種盆即可在有限的空間下養殖更多的水生生物以及栽種更多的植物以創造出更大的經濟效益。此外，本創作僅須利用一抽液件抽取液體，並再藉由一第一虹吸件、一第二虹吸件、一間隔物件、一排液件、以及一輸液件即可簡單地完成該層架式魚菜共生系統中液體的循環。
