CATDOLL : CATDOLL: What are the technologies for cultivating conch in greenhouses? Conch farming?

1. What is the technology for cultivating conch in greenhouse?

1. Breeding environment

When breeding conchs, you must pay attention to controlling the breeding environment. Do not breed them together with other shellfish. Keep them away from the same species of shellfish to prevent them from competing for nutrition and fighting. Determine the breeding quantity based on funds, breeding technology, etc., and then reasonably control the breeding area. The breeding farm should be surrounded by iron nets to ensure that it is strong enough to prevent the conchs from escaping or other shellfish from entering the breeding area during the breeding process. Insert an appropriate amount of small bamboo poles in the fence to help the conchs climb up the bamboo poles to breathe during the high temperature and lack of oxygen in summer.

2. Seedling selection

The selection of conch seedlings is very simple. Generally, they are caught in the ocean. Fresh conchs with lighter color, complete and thin shells are selected. At present, the number of artificial seedlings in my country is relatively small, and only a few docks in coastal provinces sell them in small quantities. After selecting the seedlings, wash them clean, and then put them into baskets for uniform speed. When stocking, pay attention to the stocking density. Never stock too densely. Evenly sow them in the prepared breeding sea area. Then do a good job of management to ensure the growth of conchs and improve the survival rate.

3. Feeding management

After stocking, pay attention to the seawater temperature and control the water temperature at around 15-30 degrees. Conchs are omnivorous shellfish. When they are artificially cultured, the feed is mainly small fish, shrimp and shellfish. We also need to pay attention to the content of diatoms in seawater, because conchs also feed on diatoms. Therefore, when there are fewer diatoms, the feeding amount should be increased, and vice versa. Check the feeding situation of the conchs about 3 days to prevent overfeeding from causing water quality deterioration, black bottom mud, and causing diseases and insect pests of the conchs. If there is a climbing phenomenon, oxygen should be added in time to adjust the water quality and promote the growth of the conchs.

4. Notes

The main breeding method of conch is captive breeding, which is a dense aquaculture project. It can be properly caught in July and August every year, following the principle of retaining the strong and supplementing the weak. For some conchs that do not meet the listing standards, they should continue to be raised and can be used as seedlings or sold on the market in the second year. Conchs have strong adaptability, but they grow faster in a suitable environment, so attention should be paid to water quality changes during the breeding process. Adjust the ratio of bacteria and algae in the water, clean the seine regularly, control the amount of bait, control the dissolved oxygen, and treat the disease in time to prevent cross infection.

Conchs have strong adaptability, but they grow faster in a suitable environment, so it is important to pay attention to changes in water quality during the breeding process. In addition, it should be noted that conchs are not suitable for breeding in fresh water.

3. Farming of conch?

.

The breeding environment should be away from other shellfish in the pond. Choose a relatively flat area of ​​about 5-6 acres, surround it with a 22-acre net, and treat the bottom well to prevent escape and affect the growth of other shellfish. Small bamboo poles should be inserted in the middle of the net to prepare for the snails to climb up and breathe during the high temperature and oxygen-deficient season. During the breeding process, the nets should be cleaned frequently to ensure unobstructed water flow inside and outside the net to ensure sufficient algae and shorten the breeding cycle.

2.

Seedling selection: Seedlings are mainly sourced from marine fishing, with less artificial seedlings. They are available for sale from fishing boats at local docks such as Haitou, Zhewang, and Chengdong in February and March each year. In addition, they are available at Yanwei Port in March and April. Seedlings should preferably be 20 grains/catties, healthy, undamaged, cleaned and transported in baskets. When stocking, spread the seedlings evenly in the prepared seine.

3.

The physical and chemical indicators of seawater adapted to the management and feeding of snails are as follows: salinity 10‰-30‰, pH value 7.5-8.8, nitrite below 0.10ppm, transparency about 30cm. When the water temperature is 10-35℃ within the above physical and chemical indicators, snails grow faster. Snails have a wide range of diets, and feed mainly small fish and low-priced shellfish. At the same time, pay attention to the diatom content in the water. Snails also filter diatoms. The daily feeding amount depends on the water quality of the pond. Ponds lacking diatoms should be fed more, and vice versa. Check the feeding situation of snails every 2-3 days to prevent excessive feeding from deteriorating the bottom quality. Pay attention to changes in pond water quality to prevent the bottom mud from turning black and causing lesions. When climbing poles, use granular oxygen in time, spray the bottom to change, and use EM water king regularly to adjust the water quality and keep the beneficial bacteria in the pond as the dominant population, thereby promoting the growth of aquatic animals. The low-priced shellfish fed in the middle and late stages of conch farming are relatively large. You can choose other places in the pond. When stocking conch seedlings, you can also stock some low-priced shellfish to prepare for catching when needed and feed them as feed. Since there are many bottom shellfish in the mixed pond and the daily filter food intake is large, you must pay attention to fertilizing the water during the breeding cycle. When fertilizing the water, you must choose a large-brand biological fertilizer product from a regular manufacturer to ensure the number of algae species and the reproduction of algae.

4.

Increase production and increase income. Conch farming is mainly intensive farming, which occupies a small pond area. The number of seedlings per mu should be controlled at about 12,000. After the Mid-Autumn Festival, large ones can be caught intermittently and small ones can be kept. Conchs that do not meet the specifications during the autumn harvest should be temporarily raised in the ring ditch. They can be used as seedlings or put on the market in advance the following year. In short, conch farming is an adjunct to polyculture ponds and a condition for reducing the risks of polyculture ponds. Although conchs do not have high requirements for the growth environment, they can grow in a comfortable environment.

4. Conch farming?

You can use an ordinary glass fish tank to raise snails.

Feeding: You can feed the snails animal feed, fish, shrimp and shellfish, and algae plants. Salinity: The salinity of the water must be controlled at 1% to 3% to feed them. You can buy some sea crystals to adjust the salinity of the water. Water temperature: Anywhere between 10 degrees and 35 degrees. Water quality: The water quality must be clean and not too dirty, otherwise the snails will get sick.

6. How to breed conch?

Sea snail seedlings are usually caught in the ocean. Choose fresh and alive ones with intact shells. The farm should be surrounded by iron nets to prevent them from escaping. Insert a suitable amount of small bamboo poles into the nets to facilitate them to climb up and breathe. After stocking, control the water temperature at around 15-30℃. Feed mainly consists of small fish, shrimp, shellfish and diatoms.

8. What are the species of conch being farmed?

1. Conch

This conch is also called flat jade conch. It is distributed in many coastal areas of my country, Hokkaido, Japan, North Korea, the Philippines, Australia and other places. This snail has a long body, a round and thick shell, and an overall long biconical shape. It lives in the sand and mud on the seabed. Because it is a saprophytic creature, it reproduces quickly, and the quality of the ones that grow out is very good, and the market trading is also quite popular.

2. Red snail

The meat of the red snail is quite special, soft and tender. People also call it the horn snail. The shell is large and hard, and the snail meat is pink. It contains a lot of vitamins, iron, calcium and other nutrients. It has a preventive effect on many human diseases and has a smooth taste when eaten. It is now distributed in the waters of Bohai Sea, Dalian, Yantai, Weihai, Qingdao and other places in my country. It is one of the more precious seafood.

3. Flower snail

Flower snails grow in an environment with low water temperature. Their meat is delicious, crispy and refreshing, without a strong fishy smell. Flower snails are sold both at home and abroad. They can still grow rapidly in a low temperature environment. Now because they are distributed in my country's southeast coast, Japan and other places, the market price is relatively high, and the economic benefits generated are high.

4. Sea Cone

This is a very small conch with a spiral shell and a pointed tail. The outer shell is generally brownish yellow. The meat is also very tender and relatively thick. It is known as the "Pearl on the Plate". It contains a lot of protein, vitamins, and amino acids. It is a typical high-protein, low-fat conch variety. It is also of high edible value, especially for athlete's foot, hemorrhoids, blood in the stool, and drunkenness. It has a particularly high edible value.

5. Coconut Snail

Coconut snail, also known as papaya snail, is distributed in the East my country Sea, South China Sea, Japan and other places in China. It does not require a high breeding environment. The preciousness of this snail is that pearls are easily hidden in the snail meat, which can significantly increase the value of the coconut snail. The snail meat is also relatively rich, tender and soft, and has a good taste. It is a relatively expensive snail variety.

There are many types of conchs, and farmers can choose suitable varieties for breeding.

9. Can illegal breeding greenhouses be demolished by force?

Hello, regarding the issue of building a breeding farm on agricultural land, the Ministry of Land and Resources clearly states that it does not constitute a change in the nature and use of land. According to Article 14 of the Land Administration Law of the People's Republic of China: "The land collectively owned by farmers is contracted and operated by members of the collective economic organization to engage in planting, forestry, animal husbandry, and fishery production. The land contract management period is 30 years." Collective land is divided into basic farmland and non-basic farmland. If the occupied arable land belongs to basic farmland, it shall not be occupied to build a breeding farm. If the occupied arable land belongs to non-basic farmland, it can be used to build a breeding farm if it meets the conditions stipulated in the Animal Husbandry Law, so animal husbandry can be carried out on collective land.

10. What is the difference between farmed conch and wild conch?

The main difference between the two is taste and price.

Wild fish live on the seabed without any food. They rely on their own efforts to hunt, avoid natural enemies, and survive and grow naturally. Artificial breeding is done in a relatively flat area near the coast, surrounded by nets, and properly fed to shorten the breeding cycle. Therefore, wild fish are better than farmed ones, and the price is also higher.

Conch meat is delicate and delicious. It is rich in protein, vitamins, essential amino acids and trace elements for the human body. It is a typical high-protein, low-fat, high-calcium natural animal health food. Eating more conch can clear the lungs, improve eyesight, supplement calcium and enhance immunity, etc.
