1. Abalone is expensive, what are the techniques for abalone farming?

Abalone is a rare marine treasure, listed as the first of the eight treasures. It is delicious, tender and tasty, and has always been a delicious delicacy on people's tables. In recent years, with the steady improvement of the economic benefits of the abalone market, the artificial breeding of abalone has also developed rapidly. However, abalone breeding has high technical requirements and many methods. If it is not suitable, it may cause breeding risks. So, what are the methods for breeding abalone? How to carry out daily breeding management?

1. Stone cover farming. This method is suitable for farming in intertidal sea areas. Long strips of stones are piled up as the farming area. It should be noted that the stacking direction of the stones should be consistent with the direction of the tide. After the stacking is completed, the stone pile is covered with two layers of stone cover nets with the stone pile as the center. The bottom area is about 12 to 18 square meters and the center height is 70 cm. This can effectively prevent the invasion of enemies.

2. Seabed caisson culture. This method is to place abalone in a box, and then place the box on the seabed for culture. This method requires the use of some professional culture tools and equipment, such as culture cages, steel nets, etc.

3. Build a pond for breeding. The obvious way is to choose a suitable location and build an abalone pond. It should be noted that when building the pond, some water outlets should be built, which is conducive to both drainage and water discharge.

4. Ground farming. This method is fundamentally different from traditional marine farming. Abalone can be raised in some ground farming boxes. The boxes should be large enough to provide abalone with a good growth space. In addition, the boxes need to be arranged in order, and there should be an operating channel in the middle of each box to facilitate daily management and feeding. Proper ventilation should be carried out every day.

The daily management of abalone mainly includes the selection of abalone seedlings, daily feeding of bait and disease prevention. When selecting abalone seedlings, try to choose abalone with large body, complete shell and complete physique, so as to ensure the survival rate of abalone. In terms of feed feeding, the bait processing work needs to be done in advance. Abalone's food mainly consists of kelp, kale and water shield, and the amount of abalone's food varies with the season.

If not managed properly, abalone will also get sick. Ordinary abalone basically has solitary syndrome. The symptoms of abalone are slow movement, reduced food intake, accompanied by white spherical pus bubbles, and pus overflow. In severe cases, abalone muscles will ulcerate and necrotize. It is recommended to soak for 3 hours with 3.12g of aspergillus per cubic meter, once a day, for three days as a course of treatment. Chloramphenicol or aspergillus plus 5% silver sea water solution can also be used to wipe the wound, which has a good inhibitory and therapeutic effect on the disease.

The above are some common abalone breeding boxes and daily breeding management points. However, no matter which breeding method and management points are used, they must be adapted to local conditions and reasonably arranged according to actual growth conditions to maximize breeding benefits.

When adopting dry breeding, it should be noted that the direction of stone accumulation should be consistent with the direction of tide, which can effectively prevent the invasion of enemies. Pay attention to controlling the light intensity, and only feed artificial feed for breeding. In the early stage, powdered bait can be used, and in the later stage, flake bait can be used. It should be noted that we should feed a reasonable amount according to our own high-sensitivity breeding density.

First, the caisson farming model is adopted when breeding abalone. Second, areas suitable for the ecological characteristics of abalone are selected for breeding. Abalone likes kelp and Sargassum, which are very abundant in the coastal areas of Guangxi. Third, when choosing abalone seedlings, we should choose seedlings with good vitality and suitable for breeding.

It is necessary to ensure that the water quality is suitable, the water temperature and pH value are suitable for the survival of abalone, and attention should be paid to the microorganisms in the water and whether the plankton content is sufficient to provide basic nutrients for abalone.

Choose high-quality water sources for breeding, add appropriate amount of salt to the water to imitate seawater, plant aquatic plants in the breeding area, do a good job of drainage, choose high-quality feed for feeding, and regularly check the growth environment and growth conditions.

2. Is it risky to raise abalone? Is it troublesome? Is the investment large? How much can you earn?

Of course there are risks, and it requires a certain amount of human and material investment. The abalone industry is usually divided into two stages: seedling cultivation and growth. As for the growth stage, that is, the so-called abalone farming, it is divided into two models: northern and southern farming. Recently, the more popular method is north-south relay farming, which requires many links to be connected, such as renting fish rafts in the south, and building good relations with local government departments in the south. I am doing research in this area, and I will contact you if you need it.

It shouldn't be that easy to raise.

3. How to cultivate abalone?

Abalone is one of the marine treasures living in the ocean, and its nutritional value and economic value are very high. Abalone is tender and delicious, and is favored by consumers. It is the most common high-end delicacy on people's tables and is listed as the "first of the eight delicacies". The following editor will introduce the artificial breeding technology of abalone. 1. Seedling conditions 1. Mature parent abalone: ​​Select healthy abalone without damage, generally with a shell length of more than 6 cm, and the appearance of the gonads is required to be extremely full, covering most of the digestive glands, and the gonads protrude from the shell edge. 2. Prepare the parent abalone temporary breeding pool and the young abalone breeding pool, and black plastic cloth is needed to promote seedling breeding. 3. Collector: Mainly made of transparent plexiglass, polyethylene plastic algae board and film. 4. Collection frame: Made of steel bars, wrapped with film, or made of thin bamboo and wood. 2. Breeding method Abalone generally takes seaweed as its main food. They like clean and fresh seaweed as bait. If you choose to soak dry algae, you can also eat it. When abalone is cultivated artificially, the selection of abalone seedlings is very critical. Seedlings with bright colors, uniform sizes, and no obvious scars on the shells should be selected as seedlings. Generally, seedlings with a length of 2 cm are most suitable. It is necessary to observe whether the growth line and adsorption capacity of the abalone seedlings are strong. Selecting abalone seedlings with vigorous vitality can improve the ability to resist rolling skin bending disease. Abalone is usually cultivated in cages. At the same time, a plastic cage is placed in the cage, which is about the size of two soap boxes, and then neatly hung in the cage. Another very important task in cultivating aquatic products in the sea is to clean the cages, because over time, a lot of seaweed and other things will be attached to the net, thereby hindering the flow of water. At the same time, seaweed and other substances are easy to rot and breed bacteria, so they must be removed in time. 3. Daily management In daily management, we must do a good job of keeping a close eye on the feeding. The abalone seedlings that have just been put into production are mainly fed with seaweed, and artificial feeding is carried out in combination with actual conditions. In autumn, because there is relatively less bait in the sea, it is necessary to pay attention to artificial feeding. That is, the dried kelp is processed and turned into bait for feeding. Whether the feeding is timely and scientific is directly related to whether the abalone babies can grow quickly. If they are highly nutritious, the corresponding disease resistance will also be greatly enhanced. 4. Disease prevention and control When breeding abalone, it is necessary to prevent diseases. Because abalone grows at sea, it is basically unreliable to use medicine to treat diseases, and the cost is also very high. Therefore, the breeding of abalone is mainly prevention-oriented. In normal times, the water quality and environment must be controlled well, and the feed must be kept clean and fresh, so as to prevent diseases in time. The above is the artificial breeding technology of abalone. Abalone breeding is a high-input, high-output, and high-efficiency aquaculture project, and the breeding cycle is long, and the requirements for breeding technology are also high. Therefore, abalone breeding has certain investment risks, but its breeding profits are very considerable. Farmers who want to raise abalone must master the breeding techniques, investigate the market, and find good sales channels.

Abalone feeds on algae and plankton.

Abalone is very delicate and difficult to breed. If you are not careful, the whole army will be wiped out. Therefore, scientific water purification methods are essential. It is impossible to breed abalone with directly introduced seawater. It needs to be purified. Farmers have always used sand filtration technology to purify seawater. In addition, ultraviolet light seawater purification technology can kill some bacteria and microorganisms in seawater that are not conducive to the growth of abalone, while retaining microorganisms that are beneficial to the growth of abalone, greatly increasing the yield of abalone and the survival rate of abalone seedlings by nearly 70%.

Autumn is a season of rapid growth, and sufficient fresh bait needs to be fed every 4 to 5 days. In winter, the water temperature is low, and the abalone eats less. Fresh algae will not rot after being soaked in water for 7 to 8 days, so it is sufficient to feed once every 8 to 10 days in winter. Zheng Chansen noted that each feeding should be done after removing the bait residue and abalone excrement and replacing fresh seawater. Abalone likes dry young seaweed. In the absence of fresh seaweed, dry algae can be soaked and fed as bait, and algae feeding is better with mixed effect. Among the algae, wakame, goose intestines, kelp, horsetail, etc. are seaweeds that abalone likes to eat more, with good bait effect and fast growth rate. The test results of laver, which is relatively abundant in local resources, show that it is not ideal and has a great impact on the digestion of abalone.
