specific Embodiment approach 1
[0006] Specific embodiment one: the silver carp of the present embodiment and the method for controlling algae combined with Cladophora are completed by the following steps: a, the silver carp are stocked in a suitable place to breed: to the eutrophication raw water of waterworks, throwing density is 60~100g / m 3 silver carp, the weight of a single fish is 60-200g; b, the construction of the floating cage: in the eutrophic raw water of the water plant, an open cage is made of a stainless steel wire mesh with an aperture of 3-7mm, and the length of the cage is × width The × heights are 1~2m×1~2m×1~2m, and the inside of the cage is fixed with nylon wire mesh parallel to each other and perpendicular to the bottom of the cage, and the nylon mesh is sewed to the bottom surface of the cage and the corresponding side wall of the cage respectively Together, the aperture of the nylon wire mesh is 1.2-1.8 cm, and the four-corner fixed floats on the top of the cage form a floating cage.
