specific Embodiment approach
[0021] By setting up floating-valve cages in the lake area where cyanobacteria frequently occurs, stocking tilapia with a certain density in the cage, and using the tilapia to directly feed on cyanobacteria, effective biological control of cyanobacteria in the water body, and control of cyanobacteria in the lake area Excessive growth, inhibiting the outbreak of cyanobacteria blooms. Through the method of tilapia feeding on cyanobacteria, the nitrogen and phosphorus enriched in the water body can be effectively removed, so as to achieve the purpose of removing pollution and purifying water quality. The specific implementation is as follows:
[0022] 1. Manufacture of floating valve net cage:
[0023] The net is made of polyethylene net rope, the box is made of polyethylene netting, the frame is made of double rows of moso bamboo wire twisted, and the floating part is a circular plastic foam. Net cage specification network port (2×3)m 2 or (3×4)m 2 , Cage depth 2m ~ 2.5m. M...
