specific Embodiment approach 1
[0005] Specific embodiment one: the method of the present embodiment is: one, the stocking of bighead carp and grass carp: in the eutrophication water body, the feeding amount of bighead carp is 60~100g / m 3 , the weight of a single tail of bighead carp is 60-200g; the dosage of grass carp in eutrophic water is 20-60g / m 3 , the weight of a single grass carp tail is 30-100g; the weight ratio of bighead carp to grass carp is 3:1-4:1. Net cage, the length × width × height of the floating net cage is (1~2m)×(1~2m)×(1~2m). 0.2-0.4m, two pieces of nylon wire mesh with a diameter of 1-2cm parallel to the side wall and perpendicular to the upper and lower bottoms are fixed inside the floating cage. The wall and the lower bottom are sewn together, and the distance between the two pieces of nylon mesh and the side walls of the floating cage parallel to it is 30-35cm. Cladophora grows attached to the nylon mesh, and at the same time, the net cage There are transparent daphnia with a den...
