[0031] Application Cases

[0032] This aquatic floating three-dimensional aquaculture combined device has been used in the workshop pools and ponds of Wuming Base in Nanning, Guangxi. The cage float frame of the device is made of 30 mm diameter PVC pipes and joint components, with a length, width and height of 1.5×1×0.4 meters; the wide-mouth narrow-bottom cage is sewn from 9-mesh polyethylene mesh, with an upper mouth length and width of 1.5×1 meters, a lower bottom of 1.2×1 meters, a cage depth of 0.6 meters, and an anti-shrimp (frog) enclosure film sewn on the outer edge of the upper mouth; the semi-submersible aquaculture platform is 1.2×1×0.4 meters in length, width and height, and is made of two 110 mm diameter PVC pipes and joint components (to make U-shaped pipes) and four 75 mm diameter PVC pipes. The space formed by the four 75 mm diameter PVC pipes uses a plastic mesh with a 5 cm aperture. The package is stretched and tightened into two planes; the fence-type feeding frame is fixed in the center of the large-pore plastic net on the upper layer of the semi-submersible breeding platform, and is connected by four 25 mm diameter PVC pipes and right-angle elbows to form a rectangular frame with a length equal to the width of the semi-submersible breeding platform, that is, 1 meter. Holes are drilled on the inner sides of the PVC pipes on the two long sides of the frame, and plastic tubes are inserted to form a fence; the shade cover is 1.52×1×0.2 meters in length, width and height, and is made of four 50 mm diameter PVC pipes and a three-dimensional tee, a 50 mm diameter to 110 mm diameter reducer, and a black shade mesh. The black shade mesh is opened at the center of the frame, and the fence-type feeding frame is directly below it.

[0033] After the device is assembled as a whole, water is poured into the U-shaped water level regulating pipe of the device until the semi-submersible breeding platform, which is a component, sinks to the plane of the upper macroporous plastic net, and is placed in water for one week. After the algae in the water attach to it, the breeding seedlings are put in. First, 150 loach seedlings with no disease or injury and a total length of 5 cm are gently placed in the semi-submersible breeding platform. After they swim down to the bottom of the wide-mouthed narrow-bottomed net cage, 300 yellow eel seedlings with a total length of 18-20 cm are put in, and covered with a shade cover. Three days later, the formal feeding work is carried out at a ratio of 12% of the seedlings' weight. Feeding is carried out at 17:00 every afternoon. When feeding, gently press or move the device, knead the bait into a ball, and place the bait from the feeding port in the center of the shade cover into the fence-type feeding frame fixed in the center of the semi-submersible breeding platform. After feeding for 1 hour, the residual bait in the fence-type feeding frame is crushed and sunk to the bottom of the wide-mouthed narrow-bottomed net cage, and the water quality is detected and recorded at the same time. Spray the biological agent EM bacteria stock solution once every 10 days, remove the dead fish immediately for harmless treatment, and give timely prevention and treatment according to the symptoms. After nearly 10 months of breeding, the average size of the eels produced by the device reached 2-3 taels, and the average size of the loach was 30 grams, with a survival rate of more than 85%. The dissolved oxygen in the breeding water was sufficient at all stages, and the ammonia nitrogen index and nitrite index of the water quality test were maintained below 0.02 mg / L. When catching, the shade cover and semi-submersible breeding platform are taken out of the wide-mouthed narrow-bottomed cage in turn, the wide-mouthed narrow-bottomed cage mouth is tightened, and the eels and loaches in the cage are concentrated and moved out of the cage floating frame for screening and sale.
