Mastering the breeding technology can be easily cultivated, what is the clam breeding technology?

Clams are one of the four major cultured shellfish in China, and their meat is delicious and nutritious, containing protein, sugar, carbohydrates and a variety of nutrients, and is loved by many customers. With the expansion of market demand, its total breeding area is also slowly expanding, and the clam farming technology is produced by the pro-farmer net.

Back to master the breeding technology to easily breed, what is the clam breeding technology?

1. Breeding sites.

The origin of clam breeding should be selected in the tidal flat of the valley area where the fashion trend is smooth, the terrain is flat, and the sand content is high, or in the pond with good water and sediment standards, and the road transportation standards of the aquaculture origin must be good, so as to avoid industrial production pollution. The tidal flat aquaculture should be changed to the tidal flat, and the fine sand turned out will be leveled after being washed by the tide and exposed to the sun, and the embankment should be built for flood control in the area that is easy to be washed by the tide and covered by the fine sand, so as to avoid the outflow of seedlings. The pond aquaculture should do a good job in the river embankment, sluice repair, before the seedlings in January to drain the water surface, expose the sediment, do a good job of disinfection and sterilization, in the discharge of the sea surface aquaculture.

2. Sowing seedlings. The time of seedling sowing is clear with the size of the seedling, generally the white seedlings are in April and May, and the middle seedlings are in December to next spring, and the large seedlings are before laying eggs. There are two ways to sow seedlings, dry sowing and wet sowing, dry sowing after the tide recedes and the exposed ground is sown, and the clam seedlings are evenly sown to avoid large piles; Wet sowing is when the tide has not disappeared, in the area where the fashion trend is slow, the planting time of wet sowing is long, and the survival rate is high, but only suitable for large and medium-sized seedlings.

The relative density of seedlings must be paid attention to, the relative density of seedlings is very large, the growth and development of clams is stunted, but the relative density is too thin, the production is low, so it is necessary to grasp the relative density of seedlings.

3. Strengthen management.

After sowing seedlings, it is necessary to frequently inspect the management methods to check whether the seedlings are outflowing, how the growth rate and survival rate of clams are, and to facilitate the immediate replenishment of seedlings and make relevant countermeasures. In addition, it is also necessary to pay attention to the restoration work of Chengdi and river embankments to avoid clams escaping, in addition, the clams that have just been bred are extremely weak in physical fitness, and often float to the ground.

4. Strengthen disease prevention and control.

Disease prevention and control should be strengthened during breeding, especially in the summer when the high temperature natural environment is the stage of clam disease, and often after the clams die and rot, they often feel each other after they die and rot. In addition, high temperature weather is easy to make the water body and sediment be polluted by the environment, is the breeding period of Schizocephalus and microbial strains, to carry out disinfection and sterilization of the breeding origin on time, you can use quicklime powder or chlorine dioxide to sprinkle disinfection and sterilization of water quality. In addition, when raising seedlings in summer, oxytetracycline can be added to the water quality to prevent pests and diseases, inhibit the breeding of small seedlings, and benefit the growth and development of clams.

The above is the clam breeding technology produced by the pro-agricultural net, and the clam breeding technology is introduced in detail here, I hope it can help you.

When breeding, we must first find a beach away from industrial pollution, and then the sand content must be particularly high, and the water quality must be relatively clear, and then we must strengthen management, and then we must circle this piece of beach, there must be personnel waiting, and do not step on it during the seedling hunting.

It is necessary to learn technical management skills, pay attention to water temperature, but also pay attention to the way of breeding, choose the right breeding site, pay attention to the time of seedling sowing, and understand the specific breeding cycle.

To choose a good geographical environment for aquaculture, we should pay attention to the principles of aquaculture, pay attention to the management during aquaculture, and also pay attention to the construction of ponds and understand the situation of water sources.

There is a difference between them. The harm of staying up late and not being able to sleep is not the same. Trouble falling asleep may be due to insomnia. Staying up late is because I don't want to sleep because I'm excited.

Good breeding geographical environment, pay attention to the principle of breeding, pay attention to the management during breeding, pay attention to the pond, understand the water source.

Clams are shellfish that grow on the seashore, and the common species is variegated clams. When variegated clams are harvested, they are usually landed at the same time for thousands or tens of thousands of catties, and the shells inside are selected and sorted by workers. I don't know when people invented this mud separation method.

A few years ago, I participated in clam farming and experienced this method of removing empty clams. I would like to share it with you.

<> is to make mud and prepare it for harvest. The master is in the folk, this sentence is true. Farmers build a cement pond on the shore and pull some soil from the fields.

When harvesting clams, farmers pump some seawater into the pond before going ashore. Then, they add the mud from the trolley to the water, stirring while until a slightly thicker mud is formed. Sieve to remove broken shells and impurities.

Dead clams are part of the clam farming process, and at harvest time, the empty shells are mixed with the clams and brought ashore.

At the same time, the harvested clams contain other impurities, such as small shellfish. Clams that have just come ashore first have to pass through a sieve. The sieve, which is made by the farmers themselves with angle iron, iron plates, and steel bars, used to be hand-screened by two people, but now most of them are electric.

Electric sieves are generally divided into two lanes, and the size of the sieve is also different. The first sieve hole is small, and the crushed mussel shell is sieved out; The second sieve hole is slightly larger, which sieves out small mussels and other impurities, and then puts them into the sea for the separation of the culture slurry. An electric sieve was used to remove broken shells and impurities, and the clams were sent directly into the mud pool, where workers kept stirring so that all the clams that fell into the pool were hung with mud.

After manual agitation, the empty shells settle at the bottom of the pool, while the live clams float on top of the mud, which are fished out with nets.

Rinse off the mud. After live clams are removed from the mud pool, their shells are covered with mud. Workers pump out seawater and rinse the clams repeatedly to remove the mud from their shells and restore them to their true color.

Hand-picked. Most of the empty shells can be removed by mud separation, but some shells and other shellfish can still be mixed in with clams. Therefore, the final step in cleaning clams is to go through simple manual sorting.

With the previous slurry separation step, manual sorting in this step is much easier.

When breeding clams, we must pay attention to the temperature problem, do not freeze the clams to death, and when breeding clams, we must pay attention to the problem of feed, never feed low-end feed, and when breeding clams, we must pay attention to environmental problems, do not let clams grow in places with poor environments, but I think the most important point is that when breeding clams, we must pay attention to the details, and do not bring unnecessary trouble to yourself.

The key points of clam breeding technology are: to choose a flat breeding site, and to do a good job of cleaning and disinfection, choose a pond with high water quality, maintain a suitable water temperature, clams are suitable for growing in seawater with high salinity, not suitable for growing in fresh water, so we must pay attention to the salt content of good water.

Choosing excellent varieties, preparing fresh water, and oxygen concentrators, it is best to do your own farm, do a good job of disinfection, and control the water temperature, which are all technical points.

Choose near the beach with a lot of sand, choose a relatively flat and smooth place to breed, and pay attention to the size of each batch of clam seedlings when selecting seedlings, and there is no damage to the shell. When raising seedlings in summer, oxytetracycline can be added to the water body to control diseases.

1.The aquaculture water environment is very strict, the water temperature should also be suitable, and the water needs to be changed regularly to ensure that there is no problem with the water quality; 2.Samples should be tested every month to check the growth of clams and supplement their nutrition; 3.

Nutrient is very important, you can use fresh small fish and shrimp slurry to sprinkle fertilizer water and increase the amount of organic debris in the pond, but also to supplement it with appropriate compound fertilizer.

Choose flat, pollution-free, high-sand tidal flats, and the sowing time depends on the size of the seedlings. Generally, the seedlings are in April-May, the middle seedlings are in December-the following spring, and the large seedlings are before egg-laying. Both dry and wet sowing are available.

1.The first thing to do in the cultivation of clams is to choose a place, which must be clean, clean, and disinfected before stocking.

2.The choice of seedling sowing time is also particular, it is best to choose in April-May, and the survival rate should be larger.

3.Disease prevention and control is also very important, in the summer hot weather is the high incidence of clam disease, to regularly sanitize the breeding area.

Clams are common seafood, and clam farming techniques have these:1The breeding site should be selected in the middle and low tide areas with a sediment content of 70% and 90%; 2.

When sowing seedlings, it should be carried out when the tide is low or the tide is slow, which can avoid the loss of clam seedlings; 3.The sowing density of seedlings is determined according to the size of the clam seedlings, the height of the tidal area, and the substrate conditions.

When breeding clams, you should choose tidal flats, the environment should be very good, there can be no pollution, you should do a good job of anti-escape measures, you should regularly disinfect, you should change the water regularly, sow in April and May every year, the density should not be too high when sowing, you should feed regularly after sowing, and you should also observe the survival rate of Gali, and you should regularly put vaccines to avoid clam disease.

It is necessary to pay attention to the time of clam reproduction, during the breeding period of clams, it is necessary to pay strict attention to the water temperature, to ensure that the water temperature is between 26 and 28, in addition to paying attention to the sandy quality of the clam life, to ensure that the sand content is more than 75%, and to disinfect the environment where the clams live in time.

Clams are rare seafood, and clam farming techniques have these. The breeding site should be in the tidal flat of the medium and low tide area with a sediment content; Seeding should be done at low tide or at slow tide, which may prevent the loss of clams;

The sowing density of the seedlings follows the concave and convex areas of the large and small tidal areas of the individual clam seedlings.

The breeding ground must be flat, the sediment content must be high, the water quality must be very good, and the transportation conditions must be good, and there must be no pollution.

Clam breeding to catch seedlings, after sowing to check the distribution of seedlings in time, the distribution of too dense, too thin or partially dead seedlings should be replaced in time. Clam farming catches and colonizes. After 6 or 7 months of cultivation, the individual seedlings are enlarged, the amount of food increases, and the ability to resist predators is enhanced, and the seedlings should be moved to the low tide area to accelerate their growth.

Clam farming should do a good job in disaster prevention. In areas that are susceptible to pollutants such as typhoons, floods, extreme heat, and oil slicks, preventive measures and rescue measures should be taken. Harvest early before a typhoon or move to a safe area.

After the flood, it is necessary to clean up the sediment in time and collect the scattered clams to reduce the loss. (4) Clam breeding should be prevented from enemy pests, and frequent inspections should be carried out during the cultivation period, and serious enemies should be eliminated in a timely manner. Water temperature and water quality are monitored every morning (6:

00) and noon (14:00) to measure the water temperature and observe the water color. The daily water storage is mainly according to the water quality for water exchange, the pH value in the pool should be controlled between 7-8, the dissolved oxygen should reach more than 4mg l, the water color should be maintained in a more ideal yellow-green color, and the transparency should be controlled at 20-40cm.

Clam farming should be sampled and measured regularly.

Samples are taken every half month to measure and observe their growth. If clams are found to be too dense or locally accumulated, they should be evacuated and raised in time. As long as conditions are good, clams rarely migrate.

Bait management for clam farming. The main thing is the bait biomass in the culture pond. In early spring, spray the whole pond with fresh fish and shrimp slurry to increase the organic debris in the pond.

In summer and autumn, compound fertilizer and organic fertilizer water are used on sunny days; In late autumn and winter, soy milk is used for bait throughout the pool.

Prevention and control of clam farming diseases. Every other month, water quality disinfection and disease prevention are carried out with drugs such as quicklime (10kg mu) or chlorine dioxide (mu). The prince who blocks the enemy and prevents escape is generally tall and buried on the surface of the tidal flat, but it must be checked frequently, and if it is found that it is dumped or damaged, it must be repaired in time.

After each drainage, the beach should be carefully inspected for invasion of predators such as blue crabs, and once found, the predators should be removed in time. Farmed clams prevent intestinal protozoa from growing on the beach.

When the clam is raised, we should pay attention to the seedlings, check the distribution of the seedlings in time, the seedlings will increase, the amount of food will increase, and the anti-coagulation ability will be enhanced, the seedlings can be moved to the low-tide area to accelerate the growth, and we should also pay attention to the impact of natural disasters such as typhoons and floods on the breeding of clam seedlings.

Mainly the use of concentrated breeding, need to choose a suitable farm, and then also need to regularly replace the water source, need to feed some feed in a timely manner, must choose some nutrition more comprehensive feed, to continue to learn the method of planting, so as to improve efficiency.

The breeding mode is mainly based on the artificial breeding mode, which is relatively reliable, and can make the effect of breeding better.

The breeding model needs to strengthen management, need to learn this aspect of breeding technology, to ensure the skills of breeding, but also to frequent inspections.

There are two methods: dry sowing and wet sowing: dry sowing is to dry the dew after the tide is low, and the clam seedlings are unloaded from the moored nursery ship and placed on the ground. When sowing, it is required to sow evenly to prevent piles from gathering, if the tide has risen and can not continue to sow seedlings or sowing seedlings are not completed, the clam seedlings should be taken out, soaked in water, and then sown when the next tide comes; When the tide does not come out, the clam seedlings are transported by boat to the marked Chengdi and sown evenly in the marked area.

Sowing should be done at low tide or at low tide to avoid the loss of clam seedlings. The sowing time depends on the size of the seedlings, generally in April and May, the white seedlings, the middle seedlings in December to the following spring, and the large seedlings before spawning. Note that the water needs to be light brown.

If it clears, we need to apply some fertilizer. Generally speaking, it can mature after 1-2 years of breeding, and it can be closed when it grows to more than 3 cm. The breeding area of clams should be selected in the tidal flow, flat terrain and high sediment content in the low tide area, or in the pond with good water quality and bottom conditions, and the traffic in the breeding area should be good.

Do a good job of staying away from industrial polluted areas. Intertidal aquaculture should be turned over the beach to change the land, and the turned out silt will be washed out by the tide and exposed to the sun, and then leveled, and the embankment will be built to prevent the loss of seedlings in the areas that are susceptible to tidal erosion and silt covering. For pond aquaculture, it is necessary to do a good job in the repair of dams and sluices, drain the pond water one month before releasing seedlings, expose it to the substrate, carry out disinfection treatment, and filter the fish at the outlet.

Mainly on the harbor road near the first city and the edge of the subtidal zone, casuarina is used to prevent the loss of clam seedlings.
