The invention relates to a fish and vegetable symbiotic circulation system, which mainly comprises a cultivation box, a channel, a kinetic energy conversion unit, a culture box and a transportation unit, wherein the cultivation box is used for planting plants, and the transportation unit is extracted from the culture box. The culture water is used to water the plants, and the plants absorb the nutrients in the culture water and then convert them into clean water. The clean water flows from the channels to the culture tank for use by the fish groups, and the clean water is converted into the plant water after being used by the fish group； In particular, during the passage of the water of the tillage tank to the culture tank, the displacement of the water can be converted into kinetic energy by the kinetic energy conversion unit, and the transport unit is activated by the kinetic energy of the foregoing conversion to The culture water is pumped to the cultivation box, so that the kinetic energy and nutrients can be recycled in the fish and vegetable symbiotic circulation system.本新型為一種魚菜共生循環系統，主要包含有一耕種箱、一渠道、一動能轉換單元、一養殖箱及一運輸單元，該耕種箱供以種植植物，而運輸單元則會自養殖箱內抽取養殖水以澆灌植物，經過植物吸收養殖水內的養份進而轉化為乾淨的水，乾淨的水自渠道流至養殖箱內供魚群使用，乾淨的水經魚群使用後又轉化為養植水；特別的是，該耕種箱的水在經過渠道流至養殖箱的過程中，水位移的位能經過動能轉換單元轉為動能，在藉由前述轉化的動能啟動運輸單元，以將養殖箱內的養殖水抽至耕種箱，藉此使動能及養份能夠於此魚菜共生循環系統中反覆循環。
