CATDOLL : CATDOLL: There are many methods for abalone farming. What are they?

The annual seawater salinity is controlled at about 30% and shall not be lower than 25%. Density: 800-1000 abalone fry with a shell length of 2cm/box; 600-700 abalone fry with a shell length of 3-4cm/box; 400-600 abalone fry with a shell length of 4-5cm/box. Feeding: Feed once every 5-7 days, and feed abalone mainly with red cabbage, asparagus, and kelp. If kelp is fed to the seedlings during the period of seedling growth, the shell will grow faster and more obviously. The shell grown by eating kelp is green. If there is no kelp, red cabbage can also be fed. The shell grown by eating red cabbage is red (the same is true for asparagus).

Check all of them once; the hatching tank, filter drum, and siphon are all routinely disinfected with sodium hypochlorite, and then rinsed with filtered seawater disinfected with ultraviolet light for use; prepare microscopes, beakers, pipettes, counters, platelet counters, flashlights and other equipment that can be used at any time.

Pond farming: In areas where conditions permit, ponds can be built on land, using flowing water and aeration for farming. Factory farming: Building abalone breeding rooms, using cooling and heating systems to control water temperature. Tunnel farming: Using the natural conditions of the tunnel's own constant temperature, put something to increase weight in the cage and let the cage sink to the bottom of the sea. This growth environment is more suitable for abalone, and it grows and develops quickly. It can be fed with kelp or seaweed.

The seabed caisson is relatively simple. It is to tie the box with ropes and sink it to the seabed in a fixed place. The feed needs to be fed according to the different specifications of the growth needs of abalone. Generally, fresh and tender kelp, wakame and asparagus are the favorites of abalone. When collecting seedlings, strict requirements must be placed on the water quality. When abalone is artificially raised, the water quality requirements are very strict. The water used for collecting seedlings must be dark and precipitated for 12 hours, and then filtered twice before use.

Choose an area without any pollution sources, with water quality that meets fishery water quality standards, smooth tides and convenient transportation. Choose healthy seedlings that have been cultivated and quarantined locally, with complete body shape, full appearance, no deformities, strong vitality and strong adsorption capacity. Avoid strong winds, heavy rains and high temperatures when releasing seedlings.

First of all, you should choose a fish pond with good water quality. Then you can plant some aquatic plants when breeding. You should also keep the pond full of oxygen, put some small shrimps in it, and change the water regularly.

In daily breeding, it is necessary to regularly and irregularly check whether the cages are firm and whether there are any holes. It is necessary to ensure that the cages are not damaged or worn during the breeding process of abalone. If any problems are found, they should be repaired in time. At the same time, the growth of abalone seedlings should be monitored to prevent them from escaping through damaged parts to ensure the breeding efficiency. In the typhoon season, the cages should be safely fixed and protected to reduce the breeding risks. In addition, water quality monitoring should be done in daily work, and the water color and water quality of the breeding area should be inspected frequently. The water layer of the cages should be adjusted according to seasonal changes. The pH value of the water quality should be adjusted well. When the temperature is high in summer, sunshade should be done well.

1. Raft culture at sea: This culture method uses multiple layers of abalone cages. The diameter of the abalone cage is about 45 to 50 centimeters, and the height is about one to two meters. After one year of culture, the shell size of the abalone can reach about two to three centimeters, and after two years, it can grow to about four to five centimeters. Use four to ten layers of plastic plates or iron rods and plastic tubes to put together, and connect the abalone cages in series. The distance between each abalone cage is about 20 to 30 centimeters. The advantage of this culture is that it is very convenient to feed, manage, and replace the net.

2. Seabed caisson farming: The breeding site is a large steel-framed cage that is sunk to the seabed for breeding. In this breeding method, the abalone breeding environment is more stable than abalone cages, and the growth effect is also better, but feeding is more difficult.

3. Breeding in a pond near the sea. Choose a suitable place in the intertidal zone to build a breeding pond. Put stones, cement boards, tiles, etc. in the breeding pond as attachments for abalone. There are several water inlets on the side of the breeding pond facing the sea, which serve as channels for seawater to interact during high tide and low tide. After low tide, the seawater in the breeding pond should be kept at about one meter.
