Are pike crabs artificially farmed, and are pike crabs farmed or sea caught

Barracuda crabs are artificially farmed.

Artificially bred pike crabs have soft shells and poor mobility. There is a black substance hidden in the cracks of the abdominal shell, and the joints are blackened. The legs and claws are shorter than those of wild crabs, and they are not as strong as wild crabs.

Artificial breeding methods

1. Prepare the pond.

Prepare saltwater, and the water quality is not polluted, and the depth of the water should not exceed 6 meters when irrigating. You can put some small fish and shrimp in the water to provide natural food for the pike crab.

The pike crab likes to bask in the sun on the shore, and when building a pool, you can leave a part of the land area to satisfy its preferences. An appropriate amount of sand can be spread on the land to meet the habit of barracuda crabs like to throw sand.

2. Pond disinfection.

Before the seedlings are put into the water, the water in the pond should be drained and the silt at the bottom should be removed, leaving only a small part. Put some containers such as water bottles at the bottom of the pond to provide a more suitable adjustment space for the crabs.

Once the pond has been cleaned, an appropriate amount of water can be injected. At the same time, an appropriate amount of fertilizer is applied, and the pike crab seedlings can be put in a few days.

3. Put crab seedlings.

Due to the competitive nature of crabs, when stocking seedlings, crab seedlings should be fed separately according to their size.

The temperature of the pool should not be lower than 20, and there should not be much change up and down, and the water temperature should be strictly adjusted according to the change in air temperature.

4. Daily management.

In addition to adjusting the water temperature in time, it is also necessary to change the water in the pond in time. In the summer, when the climate is hot, you need to change the water twice a week. When the climate is hot, the appetite of the pike crab will decrease, and you can feed some small fish and shrimp and other foods that the pike crab likes.

Pay attention to the oxygen content of the pool, when there is less oxygen, it may cause a large area of pike crabs to die.

Can pike crabs be farmed? 1.Can be farmed.

Barracuda crabs can be farmed in captivity. In the process of breeding, sandy wasteland or saline-alkali land near the sea area can be selected as the breeding site, and the breeding pond can be built here. The area of the pond should be controlled between 5 and 20 acres, and the water depth should be controlled at a height of 1 meter and 5 to 2 meters.

You can also place stones and tiles at the bottom of the pond to provide a hiding place for the pike crabs. 2.Selection of crab seedlingsWhen breeding pike crabs, you should also pay attention to the selection of crab seedlings.

First of all, it is necessary to observe the appearance of crab seedlings, and select crab seedlings with normal body shape, hard shell and complete body for breeding, or observe their posture and choose crab seedlings with strong physique, strong vitality and no scars for breeding. 3.Provision of foodIn the process of breeding pike crabs, it can be fed three times a day.

When preparing the feed, you can use fresh shellfish, fish, shrimp and other foods, which need to be mashed before use. The feeding amount should be controlled at 15% of body weight, and biological immune growth agents can be mixed into the feed at noon feeding to improve the immunity of pike crabs. 4.

Water quality control: Three-wart crabs are suitable for growing in an environment with clear water quality. Therefore, in the breeding process, it is necessary to change 20% of its water every day to keep the water clear. The water temperature can also be controlled at about 20 degrees Celsius, and the salinity of the sea water can be controlled at 2%, so that the three-wart crab can grow healthily.

Portunid. It can be farmed, and the pike crab sold in the off-season vegetable market is an artificially cultivated species, while the pike crab that appears in the peak season is a wild species caught by the sea, and when breeding pike crabs, it can provide them with high protein content and mineral-rich food, so that the pike crabs can grow more robust.

1. It can be cultivated

Barracuda crabs can be farmed, after December, the pike crabs sold on the vegetable market are artificially farmed, which can make up for the lack of pike crabs in the off-season, and in the peak season of pike crab growth, most of the wild species sold in the market are caught from the sea, and the wild pike crab is glossier than the shell of the farmed pike crab.

Higher. 2. Provide food

In the process of cultivating pike crabs, shellfish can be provided for them.

Fish and shrimp-based food can also be used with special feed to supplement protein for pike crabs. In addition, when feeding shellfish and shrimp, it is necessary to mash the shell and chop the meat before using it to avoid the phenomenon of barracuda crabs fighting for food.

3. Regulate water quality

In the process of breeding pike crabs, changes in water quality need to be adjusted. It is best to control the water temperature above 18 degrees and keep the temperature difference less than eight degrees, and you can also control the pH of the water quality.

Maintain it at about eight, and you can also control the salinity in the water at about eighteen to thirty-two, so that the pike crab can grow healthily.

4. Disease prevention

In the process of breeding, measures can also be taken to prevent diseases. First of all, it is necessary to change the water regularly according to the breeding density to keep the water clean and hygienic, and you can also splash sodium trichloroisocyanurate solution into the water every ten days to eliminate the bacteria in the water and improve the immunity of the pike crab.

Barracuda crab can be artificially cultivated, in the breeding need to choose the saline-alkali land near the sea, or the barren beach as the breeding site, and then need to select the crab seedlings with normal body shape and strong physique for stocking, in the process of breeding, can provide the pike crab with high protein content, high calcium content of food, so that it grows more robust.

1. It can be cultivated

Barracuda crab can be artificially cultivated, in the process of breeding, you can choose the sandy barren beach or saline-alkali land near the sea as the breeding site, and build a breeding pond here, the pond area is controlled between five acres and twenty acres, and the water depth is controlled at a height of one meter five to two meters, and stones and tiles can also be placed at the bottom of the pond to provide a hiding area for the pike crab.

2. Selection of crab seedlings

When breeding pike crabs, it is also necessary to pay attention to the selection of crab seedlings. First of all, it is necessary to observe the appearance of crab seedlings, select crab seedlings with normal body shape, hard shell and complete body for breeding, or you can observe their posture and choose crab seedlings with strong physique, strong vitality and no scars for breeding.

3. Serve food

In the process of breeding pike crabs, they can be fed three times a day. When preparing feed, you can use fresh shellfish, fish and shrimp and other foods, and need to be mashed and used, the amount of food needs to be controlled at 15% of the body weight, and at noon feeding, you can mix biological immune growth agents into the feed to improve the immunity of the crab.

4. Water quality control

Barracuda crabs are suitable for growing in an environment with clear water quality, so in the process of breeding, it is necessary to replace 20% of the water every day to keep the water quality clear, and the water temperature can also be controlled at about 20 degrees, and the salinity of the seawater can be controlled at 2%, so that the pike crab can grow healthily.

Pond conditions: When breeding pike crabs, it is necessary to choose a pond with clean water, no pollution and salinity to build a crab pond. Crab fry stocking:

From late May to mid-June each year, the crab fry are put into the pond with neat size, robustness and vigor. Bait feeding: Provide plenty of fresh bait for the crabs and clean up food residues regularly.

1. Pond conditions

Barracuda crab is a crab that grows in the ocean, so when breeding, it is necessary to ensure that the water quality of the pond is clean, pollution-free, and has a certain degree of salinity, and the water level of the pond cannot exceed three meters, and the water temperature in winter cannot be lower than seven degrees, so as not to affect the growth of the pike crab.

2. Crab fry stocking

In the process of raising pike crabs, you can choose natural and healthy or artificially cultivated crab seedlings, and the crab seedlings are required to be neat in size and have a soft shell rate of less than 10%.

10. Strong physique, complete appendages, strong vitality, and crab seedlings are stocked from late May to mid-June every year.

3. Bait feeding

When breeding pike crabs, it is necessary to provide them with fresh and palatable bait, and the amount of food to be fed can be determined according to the water temperature and feeding rate, so as to reduce the excretion of feces, ensure that the pike crabs are full and not wasted, and prevent food residues from polluting the water quality and affecting the health of the pike crabs.

1. Barracuda crabs can be farmed.

2. Choose a suitable pond. It is best to choose a pond in a place where there is no wind and waves, and the tide can flow freely; At the same time, the water in the pond should be clean enough and rich in oxygen. It is best to have a slope made of fine sand in the pond.

Barracuda crabs like to dive into the sand, and the presence of fine sand in the pond can make them more active and vibrant; It is best to have shrimp roe and trash fish in the pond so that they have enough food.

3. Add an aerator. The aerator can continuously fill the water with oxygen to ensure that the dissolved oxygen content of the water reaches the standard value. It is conducive to the growth and breeding of pike crabs, so that they can grow healthily and have better meat quality.

4. Clean up the pond. In order to ensure the healthy growth of the pike crab and the delicious meat, we must ensure that the pond is clean. The pond should be cleaned of silt and disinfected before farming.

5. Choose high-quality pike crab seedlings. There are four types of pike crabs: green shells, yellow shells, flower shells, and purple shells, among which the green shell crab has the best quality.

6. Set up a cultivation pool. The phenomenon of bullying the small with the big in the pike crab occurs from time to time. In order to prevent larger crabs from bullying smaller crabs, we should classify and breed crabs separately according to their growth and size to ensure that each crab can grow healthily.

7. Male and female are raised separately. Due to the practice of polyculture staring method, it is found that the yield is extremely low, and the ** of male pike crabs will be much lower than that of female pike crabs in winter, and it is a good method to choose male and female to be raised separately. Not only does the yield of pike crabs be maximized, but it can also be used to select the best quality crabs in the right season, so as to maximize the benefits and improve the growth of crabs.

8. Choose the right feed. In order to make the crab live in good condition and get delicious crab meat, it is important to supplement them with the necessary nutrients in time. For the selection of feed, it is necessary to observe the growth of crabs in a realistic manner.
