BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to shellfish cultivation used for cultivating scallops, pearl oyster shellfish, oysters and other oysters that do not feed on seaweed, suspending them in the sea, and culturing them. The present invention relates to a seaweed vegetation sheet for shellfish cultivation used by being attached to a basket.

2. Description of the Related Art When cultivating shellfish that do not feed on seaweed such as scallops, pearl oysters for pearl cultivation, or oysters, they are currently suspended in nets in fishnet cages. . There are various types of aquaculture baskets, such as square baskets, round baskets, so-called pockets, and so-called windsocks. There are various sizes of fish cage cages,
For example, 1.5 min, 2 min, 3 min, 4 min for scallop culture
There are various things such as minute, 7 minute, 1 inch, etc.

[0003] Scallops take two to three years from the start of aquaculture to the size that can be sold. During that time, the scallop continues to grow. Has been replaced with a culture basket. At the time of this replacement, the number of scallops to be placed in the culture basket was reduced by the size of the scallops. Also, if foreign matter adheres to the cultivation cage during cultivation in the sea, the tide will deteriorate, so at this time the cultivation cage is replaced with a new one. The period of use (the period until replacement) of the culture basket is about 1 to 10 months, and the smaller the shellfish to be cultured, the shorter the period because the growth is remarkable. The replacement work of the above-mentioned culture baskets has been increasing since around July,
This replacement is done three or more times before the shellfish can be sold.

As mentioned above, the cultivation period is 2 to 3 years before the scallop becomes large enough to sell.
It takes years, so you have to spend several high summer temperatures in the meantime. However, oxygen deficiency occurs at that time, causing massive death of juvenile shellfish and massive death (over 90%) due to oxygen deficiency in other organisms.

It is considered that the cause of the mass death of the larvae is the bait of the scallop, and the water becomes oxygen-deficient due to the remarkable decrease of the phytoplankton which is considered to be the largest source of oxygen. Such a situation is considered to be mainly caused by the following. . The number of shellfish being cultivated exceeds the permissible range of the volume in the bay to be cultivated. . Seawater is dirty due to inflow of domestic wastewater into the bay. . Soil flowing into the bay at the same time as rain due to the overcutting of trees in the mountains, making the bay shallow, dirty, or the plants in the bay withering. . Seagrass in the bay is decreasing. . Because the farm is fixed, dust and other debris accumulate on the sea floor of the farm and have become rotted.

[0006] The problem of the mass death of juvenile shellfish as described above is that every fisherman and local residents must be careful and consider a solution, but such signs are not seen at all.
This is almost all the farms in Japan and the sea is getting thinner. For this reason, similar accidents are repeated every summer in the summer, which has become a major concern for fishermen, and a solution to this problem has been awaited.
