The invention discloses a fish and vegetable coexistence cultivating and culturing system, which comprises a water tower, fish culturing tanks, a filtering pool, planting frames and a water recycling pool, wherein the water tower is communicated and connected with the fish culturing tanks, the fish culturing tanks are connected with the filtering pool, a water delivery suction pump is arranged on the filtering pool, each planting frame comprises a frame body and a planting pipe, a suspension rod is arranged at the top part of each frame body, the two ends of each planting pipe are opened, a first biochemical cotton filling material and a second biochemical cotton filling material are arranged in each planting pipe, are used for clamping vegetable roots and have nitrifying bacteria, a strip notch is formed in the side wall of each planting pipe, the output end part of the water delivery suction pump is communicated with a drip irrigation pipe, a water recycling pipe is arranged on the water recycling pool, and a water return suction pump is arranged on the water tower. The fish and vegetable coexistence cultivating and culturing system has the beneficial effects that the water in each culturing tank circulates and flows, so the high-density fish culturing is realized; the filtered culturing water can be used for performing drip irrigation on the vegetable seedlings to provide nutrients, so the water resource is effectively utilized, the waste of water resources is prevented, and the culturing cost of the vegetables and the cleaning and labor cost of each culturing tank are reduced.
