2. Submerged caisson cultivation: The breeding equipment is a large-scale cage of 2m2m0.8m steel skeleton, which is sunk in the seabed for breeding, and some are open on the upper side and both ends, with a number of staggered transverse partitions in the middle, and the opening part has a belt. The cement tanks of the zippered nets are sunk on the sea floor for cultivation, and the feed is mainly seaweed such as kelp. 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. Perimeter pool type cultivation on the seashore: In the intertidal zone where the selection conditions are suitable, the dike is built in a pond, stones, cement boards, and tiles are placed in the pool as hidden attachments to the abalone and left on the upper part of the pool wall on the sea side. There are several water outlets, which serve as exchange channels between the pool and the outer seawater during the ebb tide. 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 farming
(1) Multi-layer tank aquaculture: It adopts a multi-layer long strip-shaped shallow water tank and is 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.
1. Sea bream farming: The cultivator uses multi-layer cages to raise the quality of cages. The multi-layered cages are 45 to 50 cm in diameter and 100 to 200 cm in height, and the 4 to 10 tier plastic trays are made of steel rods and plastic sleeves. One, layer spacing 20 ~ 30cm, outsourcing with a zipper net. Feeding, management, and replacement of net clothes are all very convenient. The bait is mainly seaweed and other seaweeds.
