1. The benefits of razor clam farming are very good. What are the environmental requirements for razor clam farming?

For external coating aquaculture, it is best to choose a location with 2-3 hours of exposure every day in the lower layer of the mid-tide zone to the low-tide zone; for mixed culture of shrimps and clams, the black mud at the bottom of the pond must be treated, and the bottom is preferably a mixture of soft mud and mud and sand. 2) Build a standard model clam field. For external coating aquaculture, whether it is cooked coating or raw coating, it must be turned over. Aquaculture should be chosen in the mid- and low-tide zones, in the inner bay or at the estuary, on flat and slightly inclined tidal flats. The tide must be smooth and the wind must be calm. It can also be cultured in ponds. Razor clams grow 30 centimeters below the sand layer, so the bottom quality requirements are relatively high. It is best to have a few centimeters of soft mud on the surface.

The razor clam candy for razor clams should be selected in areas with smooth tides. The outer coating should be selected in the lower layer of the mid-tide zone to the low-tide zone. It is best to have two to three hours of exposure every day, so that it can still enter the water at the lowest tide. Razor clams, like clams, grow in the sand by the sea. The living environment is very clean. When harvesting, they also need to be dug in the sea sand. When raising razor clams, the salinity cannot exceed 10%, and the water temperature is about 20 degrees.

During its growth process, it will adhere to some impurities in the environment, and the adhesion is relatively firm. Under normal circumstances, you can use a toothbrush to collect some salt water to brush it clean. But if it is very dirty even with the naked eye, it is recommended to use a steel wool, which can quickly remove the dirt on the surface of its shell. Razor clams in the south can still survive for a period of time under 39C temperature conditions. The suitable water temperature for the growth of razor clams is 15-30C. Within this range, the higher the temperature, the faster the growth. The adaptability range of razor clams to relative density is 1.005-1.020. Within this range, a lower relative density is beneficial to the growth of razor clams.

Raising clams in this clam trough saves labor, has high yield, few enemies and good benefits. The yield of one mu of clam trough can reach about 1,000 kg, and the highest can exceed 2,000 kg. The purchase price is 15-20 yuan/kg. Also known as Shengzi, bamboo locust, etc., this shellfish food is rectangular with pure round ends. It is mainly distributed in the north and south coasts of China. It is rich in nutrition and delicious. Razor clams are high-protein foods, which are beneficial to maintaining one's own immune function after consumption.

It is important to choose a good temperature for the breeding environment. It must not be too dry, but moist. Clams like humid places. Also, the breeding area must be large, so that the quality of the clams can be better.

It has very high requirements for the breeding environment, and also requires relatively good water quality, and also requires sufficient oxygen, and also needs to change the water in time, and also needs to do a good job of ventilation, and also needs to choose some baits with nutritional value.

The first thing is to choose a place with relatively clear water. Also, you need to ensure air circulation and sufficient oxygen within the environment. Also, you need to feed these marine organisms in a timely manner and change the water in a timely manner.

Choose a good site, try to choose a low tide area. Arrange the relevant clam fields. Master the relevant time, and then strengthen the management. It is best to plant seedlings in April every year. It is also a very profitable project. Then turn the field. Try to drain the water within three to four days. Check frequently to prevent some small animals from eating the clams.

2. Can clams be raised in cement pools?

The method of breeding razor clams in freshwater is as follows:

1) Choose a good breeding site.

For external coating culture, it is best to choose a location from the lower layer of the mid-tide zone to the low-tide zone where the area is exposed to the sun for 2-3 hours a day. For mixed culture of shrimps and clams, the black mud at the bottom of the pond must be treated, and a mixture of soft mud and muddy sand is preferred.

2) Construct standard model clam fields.

Whether it is cooked or raw coating, external coating aquaculture requires turning the coating, raking the soil, and leveling the field before stocking. The entire clam field can be divided into small ridges 3-7 meters wide, with small ditches between the ridges. The ridge surface is road-shaped and water-free. The ridges for mixed shrimp and clam culture ponds can be built in the same way as external coating, and the area should be controlled at 1/3 of the total area. The pond must be "fermented" before stocking clam seedlings.

3) Carefully select and transport razor clam seedlings.

The selection of clam seedlings must be done carefully. Avoid clam seedlings that have been soaked in fresh water or left overnight, otherwise the mortality rate will be high.

4) Sow seeds at the right time and plant at a reasonable density.

In the appropriate sowing season, early sowing is recommended, which usually ends before the Qingming Festival. Seeding should be carried out during the high tide. For external mud culture, 70 kg of 1 cm shell length clam seedlings can be sown per mu, and 60-80 kg per mu in the inner pond. Do not plant too densely. Before sowing, if it rains and there is a lot of fresh water, about 10 kg of coarse salt can be sprinkled per mu to facilitate the clam seedlings to drill holes.

5) Strengthen the management of coating room.

Razor clam farming takes as short as 6-7 months and as long as 15-16 months from the start of stocking to the end of catching. Strengthening the management of the coating is an important measure to protect and increase production. In the early stage of stocking, the coating should be checked for the survival rate of the clam seedlings, and the seedlings should be replenished in time. After the strong wind and waves, the coating surface should be leveled in time. In summer, the seedlings should be weeded in time to make the coating surface loose; after the summer ebb tide, water accumulation should be prevented to prevent the clams from being scalded to death. During the breeding period, typhoons and rainstorms before and after the White Dew should be prevented, and fish pests and diseases should be expelled in time. After entering the cold season, the pond should be covered in time. When raising clams and shrimps together, attention should be paid to feeding enough shrimp bait to prevent the shrimps from eating clams due to insufficient bait, resulting in a reduction in production. After the shrimps are caught, fertilizers can be applied to ensure the normal life of the clams.

6) Harvest at the right time and return home with the grains.

The harvesting period for razor clams is from July to August or around the Spring Festival to Qingming Festival. The harvesting of razor clams must be thorough, and try not to leave old or dead clams, otherwise it will cause hydrogen sulfide accumulation at the bottom, affecting the yield and the breeding of the next year.

3. Why are clams sold in water?

This is ice expansion. When food is boiled in hot water for a while and then soaked in ice water, it will expand and become larger. It is the same as the principle that if you put beer in the refrigerator for a long time, the beer bottle will swell and explode. When liquid turns into solid, it will expand slightly.

4. Nutrition and cooking methods of yellow clams

Razor clams (chēng) are small shellfish of the sea, belonging to the family Solenidae of the class Bivalvia. Mollusks. The shell has two clams, which are narrow and long in shape. The outer shell is egg-yellow in color, and the inner shell is white. They live in coastal waters and can also be cultivated artificially. The meat is delicious. There are several types, such as constrictor razor clams and bamboo razor clams.

Razor clam meat is delicious and nutritious. According to the test, every 100 grams of fresh meat contains 7.2 grams of protein, 1.2 grams of fat, 2.4 grams of carbohydrates, 3 grams of sugar, 133 milligrams of calcium, 114 milligrams of phosphorus, 227 milligrams of iron, and 200 kilojoules of calories. Razor clams also have certain medical effects. Razor clam meat is sweet, salty and cold, and is used for postpartum coldness, dysentery and fever. The shell can be used to treat stomach problems and sore throats.

Razor clams are easy to wash. Just rinse off the mud with running water. There is no need to keep them in salt water. They do not absorb mud and sand like other shellfish. Wash the clams, drain the water, and then you can fry them. Heat the oil in a pan, pour the clams in when the oil is hot, and stir-fry. When frying clams, the fire should be high and the hands and feet should be quick, because clams shrink easily. If you are a little slower, they will shrink and will not be delicious or tender. When frying clams, you need to add cooking wine, which can be added as soon as they are put into the pan, and then add some light soy sauce. The color is not dark but it can enhance the flavor. Sprinkle a handful of chopped green onions when taking it out of the pan. It is called "scallion oil clams". The green onions are just a garnish.

There is a science to eating razor clams, just like many people who like to eat crabs don't know to dig out the "hexagonal meat" (crab heart), and many people don't really know how to eat it. The clam and the shell are very easy to separate. Pull the clam meat out of the shell. There is a circle of dark-colored "silk" on each side of the clam meat. You need to pull this circle of things off. There is a vermicelli-like thing in the middle of the clam. It is as long as a finger and is smoother and shinier than vermicelli. This thing cannot be eaten. It is said that it is as extremely cold as the crab heart, and eating too much will hurt your body. Some people pick up the clams and stuff them into their mouths, and then spit out the two shells. Whether this way of eating is damaging to the image or not is not the point, but it is definitely harmful to the body. Clams are suitable for drinking, and they must be eaten slowly to taste their deliciousness.
