CATDOLL : CATDOLL: Many people don’t know the environmental requirements for clam farming. What are the environmental requirements for clam farming?

Clams use their well-developed axe feet to dig sand and mud and live in caves. When the tide rises to the beach surface, they extend their water tubes to breathe, eat and excrete. When the tide dries up or encounters external stimuli, the double shells close or rely on the expansion of the feet to return to the bottom of the cave, leaving two holes formed by the water tubes very close to the beach surface.

The depth of the burrows of clams varies with individual size, sediment composition and season. When the individual is small, the sediment is soft or the water temperature is high, the depth of the burrow is shallow. Larger, harder, or in cold winters, they dive deeper. But generally speaking, the depth of the cave is usually about 3 to 15 cm. The breeding area of ​​clams should be selected on the beach in the low tide area with large tidal flow, flat terrain and high sand content, or in ponds with good water quality and bottom conditions. The transportation of the breeding area should be good and it should be kept away from industrial pollution areas. Intertidal zone breeding requires turning over the beach and changing the land. The silt that has been turned over should be washed by the tide and exposed to the sun, and then leveled. It is better to build embankments and flood control in areas that are easily washed by the tide and covered by silt to prevent the loss of seedlings. For pond breeding, the dams and sluices should be repaired, the pond water should be drained one month before the seedlings are released, the bottom should be exposed, disinfected, and seawater breeding should be carried out after filtering at the outlet.

The breeding site should be in a place with convenient transportation and clean water sources. At the same time, the breeding pond should be flat and tidal. In addition, the sand content at the bottom of the pond should be more than 70%, that is, the bottom quality should be stable. It is generally recommended to use Miscanthus to build a flood control pond with a width of 30 to 40 cm and a height of 20 to 30 cm above the surface of the pond to stabilize the surface of the pond and prevent the loss of seedlings. Finally, the sea temperature should be adjusted. The temperature suitable for the growth of clams is 15℃ to 30℃, which can be used as a basis for adjustment.

You need to choose a suitable temperature, use some fresh water and lay a layer of sand and mud on the bottom of the water. Finally, you need to maintain sufficient oxygen and replace some water sources in time. The feed used must be of very high quality and maintain a certain level of hygiene and cleanliness.

When breeding dandelions, you must choose a high-quality environment, and then you need to clean the rocks and replace the water source in time to ensure that there is sufficient oxygen and gas in the water. You also need to regularly remove some aquatic plants or impurities in the water, feed some bait, and keep the water quality from being polluted.

It is necessary to maintain a very good temperature, there should be some water flow, and there should be some mud and sand at the bottom of the culture. They should be fed according to their growth. The breeding position should be adjusted more during the breeding period. This will lead to better breeding results.

Clams have relatively high requirements for the environment. Try to choose beaches with relatively flat terrain, large tidal flow, and high sand content. The depth of the cave should be about 3 to 10 centimeters. It is also necessary to stay away from polluted or contaminated industrial areas.
