Several problems to be paid attention to in abalone culture

Abalone is called "soft gold" in marine life, its taste delicious, tender and delicious, rich in nutrients, has important economic value.

1. Raft culture on sea: Multi-layer abalone cage is better. The diameter of multi-layer abalone cage is 45~50cm, the height is 100~200cm, 4~10 layers of plastic tray are connected by iron rod and plastic sleeve, the layer spacing is 20~30cm, and the outer layer is covered with net clothes with zipper. Bait, management, replacement of nets and so on are very convenient, bait to kelp and other seaweed-based.

2. Submarine caisson culture: culture equipment for 2m × 2m ×0.8m steel skeleton large cage, sinking in the seabed for culture, some with upper and both ends open, with a number of staggered horizontal partition, the opening part has a zipper net coat cement tank, sinking in the seabed for culture, bait to feed kelp and other algae. The habitat environment of abalone cultured in this way is more stable than raft culture, and the growth effect is good, but the feeding and management are more difficult.

3. Enclosed pond culture by sea: in the intertidal zone, select suitable places, build ponds around dikes, place stones, cement boards, tiles and other abalone attachment concealments in the ponds, and reserve several water outlets on the upper part of the pond wall on the seaward side as exchange channels between the pond and the outer seawater during ebb tide. After ebb tide, the seawater in the pond should be kept at a depth of about 1m, and the bait is mainly algae.

4. Land artificial culture (1) multi-layer tank culture: the use of multi-layer strip shallow tank, and with the mesh screen, attached to the plate and other equipment supporting the use. The flume is 0.5~0.7m wide, 0.3~0.4m deep, 1~ 10m long, 0.5m interval between layers. Some feeds are mainly algae, some are mainly compound feed. The culture density is 200~400 abalone per square meter of 3~5cm, and 100~150 abalone per square meter of more than 6cm.

(2) The plastic box culture pond in the pond is a cement pond with an area of 20~40m2 and a depth of 1~ 1.2 m. The plastic box is a special abalone culture box with a length of 39cm, a width of 30cm and a height of 12cm. Every 5~7 boxes are stacked into a stack and tied up. Each bundle is placed vertically in the pond and arranged into rows. An operation channel is reserved between each row. The daily water supply is not less than 3~6 times that of the culture water. The continuous ventilation is 24 hours. The bait is fresh kelp or dried kelp.
