Several issues to pay attention to during abalone farming

Abalone is called the “soft gold” among marine organisms; its flavor is delicious, its texture tender and tasty, and it is rich in nutrients, with important economic value.

1. Sea raft farming: The farming device is best as a multi-layer abalone cage; the multi-layer abalone cage has a diameter of 45-50 cm and a height of 100-200 cm. 4-10 layers of plastic trays are connected into one unit by iron rods and plastic sleeves, with a layer spacing of 20-30 cm, and the outside is wrapped with zippered netting. Feeding, management, and changing the netting are all very convenient, and the feed is mainly seaweed such as kelp.

2. Seabed submerged box farming: The farming equipment is a 2 m×2 m×0.8 m large steel-frame net cage, which is sunk to the seabed for farming. Some also use cement troughs with openings on the upper side and both ends, with several staggered horizontal partition plates in the middle, and the openings have zippered netting, which are sunk to the seabed for farming. The feed is mainly seaweed such as kelp. With this farming method, the abalone's habitat environment is more stable than in raft farming, and the growth results are also good, but feeding and management are relatively difficult.

3. Seaside enclosed pond farming: In the intertidal zone, choose a suitable location and build a pond with embankments. Place stones, cement boards, tiles, etc. in the pond as attachment and hiding structures for abalone. The upper part of the pond wall on the seaward side has several water openings, serving as exchange channels between the pond water and the open sea during high and low tides. After low tide, the seawater in the pond should be kept at a depth of about 1 m, and the feed is mainly seaweed.

4. Onshore artificial farming. (1) Multi-layer trough farming: Use multi-layer long shallow troughs, matched with equipment such as mesh screens and attachment plates. The trough is 0.5-0.7 m wide, 0.3-0.4 m deep, generally 1-10 m long, with a layer spacing of about 0.5 m. Some feed is mainly seaweed, and some is mainly compound feed. The farming density is 200-400 abalone per sq m for 3-5 cm abalone, and 100-150 abalone per sq m for those larger than 6 cm.

(2) Plastic box farming in ponds. The farming pond is a cement pond with an area of 20-40 sq m and a depth of 1-1.2 m. The plastic box is a special abalone farming box 39 cm long, 30 cm wide, and 12 cm high. Every 5-7 boxes are stacked up and down into a stack and tied together. Each bundle is placed upright in the pond and arranged in rows, with operation passages left between rows. The daily water supply is not less than 3-6 times the cultivated water volume, with continuous aeration for 24 hours, and the feed is fresh kelp or dried kelp.
