Clams are a common seafood. What are the precautions for clam farming?

The square clam, commonly known as the white clam, is named for its quadrilateral shell. Its shell is very thick and slightly quadrilateral. Both shells are extremely inflated. The top of the shell is convex, located in the center of the rear edge, slightly forward, and the tip is bent forward. The shell has a skin, the top is white, the juvenile is lavender, the near ventral edge is yellow-brown, and the ventral edge often has a narrow edge. The growth lines are obviously thicker, forming uneven concentric rings, the inner surface of the shell is white, the hinge part is wider, the left shell has a forked main tooth, and the right shell has two main teeth arranged in an "eight" shape; the front and rear teeth of both shells are lamellar, the left shell is single, and the first shell has bright double lamellar. The external ligament is small and light yellow. The internal ligament is large and yellow-brown. The adductor muscle mark is obvious, the anterior adductor muscle mark is slightly smaller and oval, and the posterior adductor muscle mark is slightly larger and nearly round. The outer coat mark is clear and close to the ventral edge.

Clam meat is edible, delicious and nutritious. Cultivating four-cornered clams is economical. 1. Proliferation methods. (1) Resource protection: Close the beach for care and protect the nursery; limit the amount of fishing, take turns to collect, prohibit human destruction, move and raise in a planned manner, and increase the amount of resources. Limit the fishing season and specifications, prohibit fishing during the breeding season, and the length of the fishing specification should be over 3.5 cm. Improve the substrate: Spreading the substrate on the good beach to provide a good attachment base for clams is an important way to increase the growth of four-cornered clams. During the seedling season, the beach is leveled to prevent flood impact and burial of floating mud. 2. Breeding methods. The site selection and preparation of farmland should be based on fine sand or muddy sand, flat and stable beaches, and medium and low tide areas. After site selection, it should be leveled and removed, and the entire farmland should be surrounded by a polyethylene net with a height of about 0.5 meters.

Larger farmland should be separated by nets and divided into several small areas to avoid the accumulation of four-cornered clams when moving. The stocking density should be determined according to the purpose of aquaculture and the conditions of the sea area, and the temporary stocking density can be higher. Generally, when larvae with a shell length of 2 cm are put into aquaculture, the density can be controlled at 50070 kg/mu. (3) When the beach is cleared and the tide recedes, the young clams are evenly scattered on the beach, and seeding can be carried out. They can also be transported by boat to pre-marked tidal flats and sown evenly at high tide. Cultivation management: Disaster prevention, pest prevention, and escape prevention should be carried out during the cultivation period. After heavy winds and heavy rains, check the blockage. If clams are accumulated due to rolling and waves, evacuate in time. Harmful snails, fish, crabs, birds, etc. in the aquaculture area should be collected or driven away frequently. In spring, young clams with a body length of 2 cm can grow to 3 cm after autumn. Four-cornered clams can be harvested when they are about 3 cm long.

First of all, it depends on the place you choose. Generally, you should choose a tidal flat with small waves and a small amount of fresh water. It is best to choose a place at mid-tide or low-tide. The land is relatively flat and the water quality is not polluted. Such a place is convenient for both the cultivation process and the later management. 2. After choosing a good place, the next step is to transport the seedlings. When transporting, remember not to transport them with water, but to transport them dry, because they are more resistant to dryness. However, winter and summer are still very different. In winter, they can survive for two or three weeks, but in summer, they can only survive for two or three days. Therefore, there must be a certain humidity during transportation, and the temperature must be controlled relatively low, which is conducive to transportation.

Breeding site. Clams should be cultured in low-tide tidal flats with smooth tides, flat terrain, and high sand content, or in ponds with good water quality and bottom conditions. The transportation conditions of the breeding site must be good and it should be far away from industrial pollution areas. For culture on tidal flats, the beach should be turned over and the mud and sand turned over should be leveled after being washed by the tide and exposed to the sun. In areas that are easily washed by the tide and covered by mud and sand, embankments should be built to prevent floods and prevent seedling loss. For pond culture, dams and sluices should be repaired. One month before stocking, the pond water should be drained, the bottom should be exposed to the sun, and disinfection should be done. Then, filtered seawater should be discharged for culture.

First, the water quality must be fertile, preferably containing rich plankton. Second, the water quality must be fresh and have sufficient oxygen. Note that weakly acidic water is not suitable for raising clams.

I always can't tell the difference between white cockles and white clams. Are white cockles and white clams the same ingredient?

I always can't tell the difference between white clams and white clams. Are white clams and white clams the same ingredient? They are not the same ingredient.

What is the difference between clams and cockles?

1. Form

Clams grow in freshwater areas and are widely distributed in waters outside Antarctica. Their shells are generally about 2-3 cm long, and some larger ones can reach 5 cm. The shell is thick and hard, round or nearly triangular, with a smooth surface, concentric contours, yellowish brown or tan, and white or green inside. Clams have 3 main teeth and 6 side teeth, which are serrated.

Clams, also known as clams, are named for their smooth shell surface and beautiful red, brown and black patterns. They are widely distributed near the North Sea and South Sea in China, Korea and Japan. They have two hard, thick round shells with slightly protruding tops. The shell is 36-48 mm long and 34-46 mm high. The inner surface is porcelain white and the overall color is monotonous.

2. Types

Ha and clams are not the same seafood. Clams are tetrahedral clams or other clams in the clam family. Clams belong to the family Corbicula, but clams are top-grade shellfish, while clams are lower-grade.

3. Method

There are many ways to cook clams, such as stir-frying, boiling, and stir-frying. The best way is to grill them over charcoal. Put the processed sand-free clams on the charcoal. When the clams are opened and cooked, you can take them out and eat them. The most delicious clam is not the meat, but the juice. The ancients said that this is called eating semen.

For clams, I think stir-fried clams are good, and the method is simple. Wash the sand out of the clams, and then stir-fry with onions, ginger, and pepper. It is especially suitable for cooking wine and vegetables. In addition, clams can also be steamed, braised, or iron plate. You will often see tinfoil flower shell shops. Cooking clams and enoki mushrooms with powder is also a good choice, but each method tastes different.

Through the above explanation, we understand the difference between clams and clams, and we also understand the two. Their nutritional content is similar, so we can distinguish them when buying them in the future. When we go home, we can choose the appropriate method. We can try different methods to enjoy the different tastes of these two foods.

Not a food ingredient. The shell of a clam is about 2-3 cm long, thick and hard, some are round, some are triangular, and the color is green or white. Clams have two hard, thick round shells, and the shell is 36-48 mm long.

White cockles and white clams are not the same food ingredient. They have different sizes, shapes, and preparation methods, and they taste different.

No, these two organisms have different shapes and are cooked differently, but their nutritional components are quite similar.
