Some problems should be noticed in abalone farming
Single Arm Electric Medical Pendant,The control cabinet of the Tower Crane adopt the imported high-strength aluminum alloy of patent technology for the one-off extrusion molding, and the surface undergoes the primary oxidation treatment.The tray surface is non-slip. Mechanical friction damping brake.The imported electrical machine is adopted , and the rising and rotation function of the electric horizontal cantilever can accurately position without excursion.The gas pipeline, power supply and computer communication line are separately arranged without interference.

The breeders use multi-layer cages to raise the cage better. The multi-layer cages have a diameter of 45-50cm and a height of 100-200cm. The 4- to 10-layer plastic trays are integrated by an iron bar and a plastic sleeve. The interval between layers is 20 to 30cm. , outsourcing with zippered nets. Feeding, management, and replacement of net clothes are all very convenient. The bait is mainly seaweed and other seaweeds.
2. Seabed caisson cultivation:
The breeding equipment is a large cage of 2m2m0.8m steel skeletons, which is sunk to the seabed for breeding, and some are open at the upper side and both ends, with a number of staggered transverse partitions in the middle, and a cement tank with a zippered net at the opening. , Sinking in the seabed for breeding, bait to feed seaweed and other seaweed-based. The breeding environment of the abalone is stable compared to the eel culture, and the growth effect is also good, but the feeding and management are relatively difficult.
3. Wai Wai Pond Farming:
In the place where the selection conditions of the intertidal zone are appropriate, the embankment will be built with pools, stones, cement boards, tiles, etc. will be used as attachments for the abalone. There will be a number of water outlets at the upper part of the pool wall on the sea side. At the time of ebb tide, the exchange channel between the inner and outer seawater. After the ebb tide, the seawater in the pool should be maintained at a depth of about 1m, and the bait is mainly seaweed.
4. Land-based aquaculture (1) Multi-layer tank culture:
Multi-layer long thin shallow water tanks are used, and are used together with mesh screens, attachment plates and other equipment. The sink is 0.5-0.7m wide, 0.3-0.4m deep, and the length is generally between 1m and 10m. The layer spacing is about 0.5m. Some of the bait are mainly seaweed, and some are mainly bait-based, and the breeding density is 3 to 5cm. 200-400 square meters, more than 6cm abalone 100-150 per square meter.
(2) The plastic tank aquaculture pond in the pond has an area of ​​20 to 40 m2 and a depth of 1 to 1.2 m. The plastic box is a 39 cm long, 30 cm wide, and 12 cm high box-bearing box. Each 5 to 7 boxes are stacked one on top of the other. A stack and bundled, the bundles are placed in the pool and arranged in rows, and the operating channels are left in each row. The daily water supply is not less than 3-6 times the cultivation water body, 24 hours continuous ventilation, and the food is fresh kelp or Dried kelp.
