Description

Suitable oyster submarine breeding device

Technical Field

The invention relates to an oyster cultivation device, in particular to a device suitable for cultivating oysters on the sea floor of the open sea, and belongs to the field of aquaculture.

Background

The oyster is one of four cultured shellfish in China, the yield of the oyster in 2019 is 522.56 ten thousand tons (the statistics yearbook of fishery in China in 2020), which accounts for 1/3 of the total shellfish culture yield in China and accounts for more than 85% of the total oyster production in the world. At present, oyster cultivation in China is mainly carried out on the surface layer of the inland sea in the north by using a traditional raft type lifting rope cultivation method on the surface layer of the shallow sea. Because the surface layer of the sea area is very large in wind waves, oysters cultured by the lifting ropes grow continuously along with the oysters, the lifting ropes are difficult to support the oysters with larger weight and larger volume, so that the oysters are easy to fall off from the lifting ropes, and the yield of the oysters is greatly reduced; and the breeding mode can not breed large-size high-quality oysters. In addition, the raft type lifting rope cultivation mode is not suitable for deep water in the open sea or sea areas with large waves, and is only suitable for inner gulf and shallow sea with calm wind and waves, so that the cultivation area is limited to the surface area of the offshore sea area, and the bottom area with less waves and attached organisms is not developed and utilized for cultivating oysters.

In addition, the raft type hanging oyster is cultured on the upper layer of the sea area, and due to strong light and more attachment organisms, a large amount of attachments such as mussels and the like are attached to the surface of the oyster cultured by the raft type hanging rope; these attachments affect both oyster growth and further oyster quality and market value. In addition, oyster is bred to raft formula lifting rope not only influences the sea area view generally at nearly bank buoyant raft, still can influence the navigation of sea ship, causes inconvenience to the marine navigation management.

Therefore, a new culture method and technology which can meet the high-quality and environment-friendly development concept of aquaculture and break through the traditional oyster culture mode are urgently needed.
