1. High score! ! How many types of clams are there? How to transport and store them?

There are many varieties of clams, and they vary according to where they grow. Long-distance transportation of clams must first shorten the transportation time - ensure that the clams are still alive after arriving at the destination, and minimize violent vibrations and severe impacts; use a van for transportation, and use a split transfer box for loading. During transportation, they cannot be thrown directly into the water, but they must be sprayed with water every once in a while on the way to prevent excessive drying and death of the clams... Wait, let me say this first, and I will add more after the bonus points are added!

There are many kinds of things, and they are different in different sea areas. Your question is very general, but you can't transport things with water. When you sell them, soak them in water to make them spit out sand. When transporting them over long distances, keep them out of light and keep them moist. Generally, there is no problem

2. 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.
