What should I do if I just raise the clam seedlings in the pond

Local norms reply to that norm and norm.

<>1. Cultivation site: The cultivation site should be a flat and slightly inclined tidal flat near the inner bay or estuary.

2. Construction of the razor field: The field is 50m long and 3m wide, dig a drainage ditch every 1m, and dig a drainage ditch around it, the ditch is 20-25cm wide and 20-30cm deep, and a dam is built at 30-40m above the clam field.

3. Transportation and sowing of razor clams: sowing seedlings before and after Qingming, and sowing 125kg of razor clams per mu.

4. Management: Keep the ditches connected, and regularly inspect the razor fields.

1. Lu Bo Ant Cultivation Venue

1. The cultivation site should be selected from the lower section of the middle tide area to the low tide area for about 2-3 hours a day, and it is advisable to have a flat and slightly inclined tidal flat near the inner bay or estuary, and it is necessary to bury the wind and waves as early as possible and have a certain water flow speed.

2. The bottom material of the cultivation site is required to be clearly stratified, with the bottom layer as pure sand, the middle 20-30cm as the sediment mixed layer, and the surface layer 3-5cm as the sedimentary soft mud layer.

Second, the model of the construction of the clam field

1. The mode clam field is about 50m long and 3m wide, and a drainage ditch is excavated every 1m interval, and the drainage ditch needs to be excavated around the silver mill clam field, with a width of 20-25cm and a depth of 20-30cm, to ensure that the tidal flat surface is smooth and slightly tile-shaped.

2. Build a low embankment about 30-40m above the razor field to avoid the tidal wave from destroying the razor field at full tide and the summer tide water flowing into the razor field to scald the razor clams.

3. In winter and spring or within 30-60 days before sowing razor clams, use a coating machine to deep turn the clam field 1-2 times, the depth is about 40-50cm, and rake flat.

3. Transportation and sowing of razor clams

1. High-quality clams and seedlings: the shells are shiny, the particles are full, the size is uniform, and there are few broken shells and impurities.

2. The transportation of razor clams is generally completed within 24 hours, and the transportation is carried out on a sunny day, the temperature is 10-15 is appropriate, and before transportation, it is necessary to carry out a damp to spit out the mud in the body of the clams.

3. Sow seedlings before and after Qingming, and the specific time is within 30 minutes before the high tide.

4. Generally, 125kg of razor clams are sown per mu, and the specifications of razor clams are 3000-6000 kg. In the process of sowing, it is required to sow seedlings evenly, sow seedlings sufficiently, and leave no dead ends.

Fourth, management

1. After the seedling is just sown, regular inspections should be carried out to avoid birds pecking.

2. Keep the ditches between the clam fields connected, the tide is smooth, and the surface of the tidal flat is not waterlogged.

3. Conduct regular inspections and use 1% sodium hydroxide solution to spray the stagnant water in the razor field to kill enemy eels, gobies and other enemies.

4. Harvest during the period from the beginning of summer to the beginning of summer, when the razor clams are the fattest and the yield is high.

To raise razor clams, we should pay attention to the following points in operation and management:

1) Choose a good breeding site. Coating culture is selected in the middle tide area, the lower layer to the low tide area, and it is better to have 2-3 hours of exposure every day; The bottom of the shrimp clam polyculture pond must deal with the black mud at the bottom of the pond, and the substrate is better with the substrate mixed with soft mud and sediment.

2) Construction of standard model clams. Whether it is cooked or raw coating, the outer coating breeding must be turned over, harrowing soil, flat Cheng can be stocked, the whole piece of razor clams can be divided into a small furrow with a width of 3-7 meters, there is a small ditch left between the furrows, the furrow surface is road shaped, not waterlogged, shrimp and clam polyculture pond with reference to the outer coating to build a furrow, the area is controlled in the total area of 1 3 is better, and the razor clams must be "haired pond" before stocking.

3) Carefully select and transport razor clams. The selection of razor clams must be done well, and the seedlings soaked in fresh water and the overnight razor clams must be avoided, otherwise the mortality rate will be higher.

4) Timely sowing and reasonable dense planting. In the suitable sowing season, advocate early sowing, generally end before the Qingming Festival, sowing seedlings should be carried out during the high tide flood, external coating breeding per mu can sow 70 kg of clam seedlings with a shell length of 1 cm, and the inner pond can be 60-80 kg per mu, do not be too dense. In case of rain and fresh water before sowing, about 10 kg of coarse salt can be sprinkled per mu to facilitate the drilling of clam seedlings.

Raising seafood artificial seawater is the need for professionals to blend, but their own short-term seafood can go to the seafood wholesale market to buy a bag of "sea crystal", the packaging bag has a specific proportion, can not be mixed with salt, sea crystal blended seawater razor clams for a week is no problem, but to change the water.

A lot of the sand in the razor clams is on top of the shell, after changing the water a few times, the sand is basically gone, normal 3-5 days, depending on how you eat, boil and eat directly or fry with the shell to blanch in boiling water and then eat it twice with water, so that the sand will be much less.

If you peel off the shell and fry the razor clam meat with coriander and shallots, then you don't have to raise it for so long!!

Light salt water, you can't use tap water, that will absorb water and swell.

1. Selection of breeding sites. Aquaculture is selected in the middle and low tide areas, in the inner bay or estuary flat and slightly inclined tidal flats, which requires that the tide must be smooth and calm, and can also be cultivated in ponds. The razor clams grow 30 cm below the sand layer, so the requirements for the substrate are higher, and it is best to have a few centimeters of soft mud on the surface, the middle is mixed with sediment, and the bottom layer is sand.

At the same time, its requirements for water quality are also extremely strict, requiring the specific gravity of seawater to be between, suitable for growing water temperature of 3-32 degrees, liking weak alkaline water bodies, and pH value.

2. Finishing of the clam field. After choosing the right breeding site, it is necessary to sort out the clam field, first of all, the site should be harrowed and ploughed, the hard bottom area should be deeply turned, and then the rake is fine, and the steps are leveled to make the soil soft and suitable for the growth of razor clams. Before sowing seedlings, they should be disinfected and sterilized, splashed with bleaching powder in the water body, and the water will be emptied after about 2-3 days, and then the small fish, shrimp and snails in the clam field should be eliminated with tea seed cake to prevent them from eating the razor clams.

3. Sowing seedlings. There is a slight difference in the sowing time between the north and the south, the temperature in the south rises quickly, and the seedlings can be sown before the Qingming Festival in April, while the seedlings in the north should be sown in late May. Before sowing seedlings, use wooden barrels or plastic buckets to hold the seedlings, and then wash the sediment with seawater, you can carry out the seedlings, and the seedlings can be sown and sown.

Throwing is suitable for the wide clams of the Cheng surface, gently grab the clams seedlings, throw them to the Cheng surface, when there is no wind, several people can cross the throwing, when there is wind, conform to the wind to throw; The sowing coarse is suitable for the narrow clams field, and the seedlings are also gently grabbed and sown vigorously on the Cheng surface.

4. Clam management. After sowing the seedlings, strengthen the management of razor clams, inspect frequently, check the growth rate of razor clams, and the survival rate of chickens, and carry out seedling replenishment and corresponding measures in a timely manner. In the summer, the temperature is hot, and the heat dissipation of the muddy ground is poor, which is not conducive to the growth of razor clams, so it is necessary to adjust the temperature of Gaza at this time, so that the clams are in a suitable growth environment.

Gaza time before June, generally per mu of Gaza tons, Gaza is required to be evenly sprinkled on the Cheng surface, in addition, during the storm, pay attention to the soil pile, timely push the silt to other areas. In the management of razor clams, it is also necessary to pay attention to natural disasters and biological predator control = work, so as not to cause huge losses.
