Alga control method for freshwater environment based on cultivation of barracudas and mullets

The invention discloses an alga control method for a freshwater environment based on cultivation of barracudas and mullets, relating to a water treatment method. Aiming at solving the problem that algae can not be stably and thoroughly controlled in a eutrophic fresh water body, the method comprises the following steps: at least introducing one species of estuarine/marine fishes, such as barracudas and mullets which can only be propagated in sea water, and carrying out desalination processing before cultivation to enable the barracudas and the mullets to be adapted to a freshwater living environment, wherein the mesh size in the large water body ensures whether the cultivated fishes can escape; dividing or mixing according to different ages, carrying out culture in enclosure in girds by meshes, and simultaneously cultivating and propagating silver carps, bighead carps, other local fishes and local shellfish; and propagating local common aquatic plants. Thus, the fishes can be fed on the algae in a filter-feeding mode and simultaneously swallow detritus substances, thereby achieving the purpose of thoroughly purifying the water environment. By harvesting the cultivated and propagated aquatic organisms to remove nitrogen/phosphorus nutrients in water and humus in bed material from the water body, the method disclosed by the invention greatly improves the water quality of the cultivation water body.
