First, the breeding method is usually used to cultivate cultured pearl mussel. First with bamboo, wooden piling, with coarse nylon rope for cross bar, stand on the water. Fixed a plastic foam or sealed empty plastic bottle every few meters on the rope to increase the buoyancy, and then placed the pearl mussel in a wire cage suspended on a rope with a row spacing of 1.5 meters and a cage distance of about 1 meter, stocking in Rope 20 to 30 cm of aquaculture, the depth of suspension should change with the seasons, the spring 25 centimeters from the surface, the summer 50 cm from the water surface, the fall from the water 40 cm,
