Artificial culture model of abalone

Abalone is one of the most valuable "sea treasures". It is delicious and nutritious, and is known as the "soft gold" of the ocean. Abalone is a valuable marine edible shellfish, known as "table gold, the crown of Haizhen". Let's take a look at several modes of artificial culture of abalone.

Submarine caisson culture:

The aquaculture equipment is a large 2m × 2m × 0.8m steel frame cage, which is cultured on the seafloor, and some use the openings on the upper side and both ends, with several staggered diaphragms in the middle, and the opening part has a cement trough with zippered mesh coats, which sinks on the seafloor for breeding, and the bait is mainly fed to seaweed such as kelp. The habitat environment of this method of abalone culture is more stable than that of raft culture, and the growth effect is better, but it is difficult to feed and manage.

Raft culture at sea:

The multi-layer abalone cage is better, the diameter of the multi-layer abalone cage is 45~50cm, the height is 100cm 200cm, the plastic plate is composed of iron rod and plastic casing, the distance between layers is 20~30cm, and there is a net coat with zipper. It is very convenient to bait, manage and change the net clothes, and the bait is mainly seaweed such as kelp.

Aquaculture by the seaside enclosure:

In the place where the selection conditions of the intertidal zone are suitable, stones, cement slabs and tiles are placed in the pool, and several water openings are left in the upper part of the pool wall on the side of the sea, which can be used as the exchange channel between the inner and outer sea water of the pool during the ebb tide. After ebb tide, the sea water in the pond should be kept at a depth of about 1 m, and the bait should be dominated by seaweed.

Land artificial culture

The main results are as follows: (1) Multi-layer flume culture: multi-layer long strip shallow flume is adopted and used with screen, attachment board and other equipment. The flume is 0.5 ~ 0.7m wide and 0.3m ~ 0.4m deep, the length is generally between 1m and 10m, and the distance between layers is about 0.5m. Some of the diets are mainly composed of seaweed and some are mainly compound diets. The culture density of 3~5cm abalone is 200mm per square meter, which is higher than that of 6cm abalone per square meter. (2) the plastic box aquaculture pond in the pond is a cement pond with an area of 20~40m2 and a depth of 1m to 1.2m. The plastic box is a special abalone culture box with long 39cm, wide 30cm and high 12cm. Every 5 to 7 boxes are stacked into a stack and bundled, and each is placed in the pool and arranged in rows. There are operating channels between the rows, the daily water supply is not less than 3 to 6 times that of the cultivated water, and the bait is fresh kelp or dry kelp.
