Razor clams often appear on people’s tables. What are the techniques for breeding razor clams?

Simulate the seawater environment in which it grows, but it is not such a good environment. The average salinity of Pacific Ocean water is 35‰, which means that 1 liter of seawater contains 35 grams of salt. If you use this concentration of salt water, the clams will breathe and spit out sand at a normal rate. Rinse the clams you bought with clean water first, then prepare a basin of clean water and add an appropriate amount of salt to dissolve it. Then, put the washed clams in the basin, and pay attention to changing the water during the process. After changing the water for the third time, add a drop of oil to the water and stir well.

But if the clams are not cleaned, the taste will be affected to some extent. Besides, the mud and sand in the clams will affect the appetite. So how to clean the clams? Let me tell you a very simple and practical trick. Never blanch them in water, which will not only affect the taste of the clam meat, but also lose nutrition. Washing the clams is the same as washing the clams and snails. Just put them in water, add salt and oil to feed for 3 to 5 hours, and then shake them continuously to clean them. Thank you, I hope my answer can help you. If you don’t follow the above steps and the cooked clams still have mud and sand, then I will teach you another first aid trick. Just remove the sandbag of the clam, and that’s it. This method is suitable for when you only want to take the clam meat and time is tight.

After about 20 to 30 minutes of standing, you will see the clams start to spit out water. After about 2 to 3 hours, the mud and sand in the clams will be spit out. During this period, you should pay attention to changing the water several times. Rinse the clams you bought with clean water first, then prepare a basin of clean water and add an appropriate amount of salt to dissolve it. Then, put the washed clams into the basin, pay attention to changing the water during this period, and add a drop of oil to the water after changing the water for the third time and stir well.

Razor clams are delicious, but if you don't clean them properly, you will eat mud and sand, which is very disappointing. So how can you clean them quickly and cleanly? I will share a trick for cleaning that is simple and practical. Razor clams will spit out mud and sand by themselves. You need to change the water several times in the middle. Generally, you should change the water three times and then add a few drops of sesame oil to the clean water. It will take about an hour. If you think there is no mud and sand in the water, it means that the clams have spit out the mud and sand by themselves and you can cook it.

To manage a clam field, after choosing a suitable breeding site, you must first harrow and plow the site, deep plow the areas with harder bottom, disinfect and sterilize them, sprinkle bleach into the water, and drain the water after about 2-3 days.

The breeding area must be very humid, preferably near a river. The hard ground must be plowed. Bleaching powder should be sprinkled in the water to kill some small fish and snails and prevent them from eating the seedlings. The time for sowing the seedlings must be chosen well. It can be chosen in April or May. Check it frequently.

After choosing a suitable breeding site, you need to prepare the clam field. First, harrow and plow the field. Deep plow the hard bottom area, then harrow and level the field to make the soil soft and suitable for the growth of clams. Before sowing the seedlings, disinfect and sterilize them. Sprinkle bleaching powder in the water. Drain the water after about 2-3 days. Use tea seed cake to kill small fish, shrimp and snails in the clam field to prevent them from eating the clam seedlings.

Few people have mastered the technology of razor clam farming. What are the main aspects of razor clam farming technology?

During the breeding process, after sowing, razor clams can be cultivated into commercial razor clams that meet market standards. This production process is called breeding. The main breeding methods of razor clams in my country are tidal flat breeding and water storage breeding. Below, Brother Feng will talk about the breeding knowledge of razor clams from three aspects, namely tidal flat breeding, water storage breeding and value-added breeding, based on the breeding technology of razor clams in our area, for reference by friends in need. The breeding site of terrain crickets should be selected in the sea area near the inner bay and estuary, where it is calm, there is fresh water injection, and the beach is flat. Because clam seedlings like to drill the soil and live in caves, the surface of the bottom material in the breeding area is preferably about 3 cm of soft mud, the middle layer is a 20-30 cm thick mud and sand mixed layer, and the bottom layer is sandy. In order to facilitate production management and observation, as well as sowing and harvesting, the razor clam breeding area should be selected in the middle and lower part of the mid-tidal zone and the upper part of the low-tidal zone, because the exposure time in this area is shorter, the feeding time is longer, and the habitat is relatively stable, which is conducive to the growth of razor clams.

The tides in tidal sea areas should be gentle and the bait should be abundant to promote the rapid growth of Sinonovacula constricta. Therefore, as long as the tide does not affect the stability of the beach, it is best to have a larger flow rate in the breeding area, and the minimum flow rate is generally required to be above 40cm/s. Salinity Sinonovacula constricta grow well in seawater with a relative density of 1.010~1.020, and it is generally required to be between 1.005~1.022. Sea areas with industrial and agricultural pollution sources cannot be selected for breeding. Cultivated production areas are generally arranged in a plowing manner, and plowing includes three steps: turning, raking, and leveling. Concrete plowing needs to be completed within 2 days before sowing. In order to prevent the impact of floods or wind and waves, embankments should be built around the estuary for protection. When building a dike, Feng Ge’s approach in the sea area is to first build a ridge dike, about 0.3m deep and 0.5m wide, then place the ridges (ferns) in bundles and stand them upright (straight ridges), and then use a bundle of ridges to cross the soil (horizontal ridges), with the horizontal ridges and the vertical ridges forming a 45° angle, and then push the sand up, with the upper end of the ridges exposed about 0.3m above the ridge surface. The construction of the ridge dike requires straightness, uniform height, and uniform thickness to minimize the impact resistance and pressure difference caused by floods and wind and waves. At the same time, in order to prevent mountain torrents from pouring over the aquaculture area, it is necessary to build a dike at the upper end, dig trenches to divert fresh water into the sea, and protect the surface from damage.

The scale of the field can be determined according to the topography of the coating surface and the direction of the tide. Generally, a drainage ditch 50m long and 3m wide is dug every 1m, and drainage ditches are opened around the field area, 20cm-25cm wide and 15cm-20cm deep. A short dam is built 30-40 meters above the field. It can prevent the tide from destroying the clam field during high tide or the water flowing into the clam field in summer from scalding the clams. Seaside topping is an important measure to improve soil quality, eliminate enemies and hazards, increase the burrowing rate of clam seedlings, and disperse toxic substances such as hydrogen sulfide in the soil layer. It is required to turn the clam field once or twice in winter, spring or 1-2 months before sowing clam seedlings, with a plowing depth of about 40cm-50cm; and harrow the surface to build a standardized model field.

According to the breeding season, razor clam seedlings can be divided into "winter seed", "spring seed" and "summer purple". Winter seedlings have the best physique and high survival rate; spring seedlings are second; summer purple is the worst. Choose seedlings with complete shells, plump seeds, uniform size, fresh and lively. Method to check the quality of razor clam seedlings: gently shake or tap the basket with your hands, and the seedlings with double shells that make a "squeaking" sound are good seedlings, and the survival rate can generally reach more than 90%. The shipment of razor clam seedlings should be done quickly, quickly, lightly and quickly, and the time on the way should be shortened as much as possible, and strive to complete it within 24 hours. Try to arrange it on a sunny day with a temperature of 10℃-15℃.

Techniques, environment, feed, temperature, soil, space, etc. must be considered comprehensively to ensure the output of breeding.

First, reasonably control the planting density, which is generally around 70 kilograms per acre; second, carefully select seedlings, as the mortality rate of seedlings soaked in fresh water is very high; third, build standard breeding places.

The first thing is to choose some areas with clear water quality, and be sure to plant some aquatic plants in the water area. Also, you must ensure the oxygen in the water area and change the water in time.

After choosing a suitable breeding site, you need to prepare the clam field. First, harrow and plow the field. Deep plow the hard bottom area, then harrow and level the field to make the soil soft and suitable for the growth of clams. Before sowing the seedlings, disinfect and sterilize them. Sprinkle bleaching powder in the water. Drain the water after about 2-3 days. Use tea seed cake to kill small fish, shrimp and snails in the clam field to prevent them from eating the clam seedlings.
