1. The pond for breeding razor clam should be at the estuary of the river, which is convenient for entering and leaving water. The bottom material is fine mud or sediment, and the aquaculture water quality should meet the pollution-free standard.

2. Mixing the bottom mud of the pond into mud can facilitate the later seedling washing. You can also cultivate a certain amount of algae in the pond, clean the pond with abamectin, triazophos emulsion and other drugs 3-5 days before sowing, completely kill the hidden pests and diseases in the pond, and sow after the medicinal properties disappear.

3. When sowing and raising seedlings, we should choose high-quality oyster seedlings, which will directly affect its yield change. Generally, the lower shell of high-quality oyster seedlings is white, clean and free of impurities. After the seedlings are selected, they are leached with seawater with appropriate concentration and then planted in the pond.

4. In order to ensure the rapid growth of SINONOVACULA constricta larvae, it is necessary to meet the needs of its biological bait, and algae culture is needed to ensure that the bait can be eaten on the same day. Usually, we should pay more attention to the algae color change of bait in water to ensure its quality. If you encounter hot weather, change the water sooner or later to prevent the larvae from being scalded by hot water.

5. The pests that need to be prevented and controlled in the prevention and control of cultured SINONOVACULA constricta are Nereis and fish. Clean the pond with Chinese herbal medicine "compound fishnet" before releasing seedlings, generally soak it in warm water for half a day, and then splash it all over the pond. It can control nereis. The triazophos emulsion is diluted and sprayed on the mud surface at the bottom of the nursery pond two days before seedling release, which can prevent fish from being injured. If the bottom of the pool stinks and rots, it needs to be improved in time. Generally, the mixed microbial inoculum of EM bacteria and Bacillus is used, and the dosage is increased or decreased according to the bottom pollution.

6. After 55-70 days of cultivation, the razor clam grows very fat, and it can be harvested properly at this time. Every year from late May to mid-June is also the peak season of razor clam consumption, and at this time, the harvest can also get higher profits.
