Japanese experts have developed a new method for breeding shellfish: they will put shellfish or oysters, which are lurking in the sand and will not migrate outward, into containers filled with sand. It is put into the seawater under cover and cultured.
The container used may be made of plastic, or it may be used as a container after being lined with a thin mesh plastic cage, as long as it is a container that does not leak sand. Sand is best used for sand, such as sand where shellfish habitat is preferred. The amount of sand loaded into the container should be such that the thickness of the grown shellfish cannot escape from the upper edge of the container.
When cultured, sand is first packed into the container and the shellfish of the inhabited sand are placed in the container. Then, place all the containers containing shellfish side by side in the shallow sea, or attach the rope to all the containers and sink the containers into the sea water. In this way, the seedlings begin to grow normally and cannot escape from the container. After the shellfish grows, the container can be easily taken out of the sea water. The more containers used, the higher the yield of shellfish.
In this method, since the sand-filled containers are not covered with rope nets but are cultured in an open state, seaweeds, floating sludge, etc. do not accumulate on the rope nets, and fresh seawater can be directly flowed into the containers to prevent shellfish. The type of death caused by lack of oxygen, but also can save the net manpower, material resources and improve the breeding efficiency.
