Description

Technical Field

[0001] The utility model relates to the technical field of artificial cultivation of seafood, in particular to an oyster cultivation cage. Background Art

[0002] Oyster cage cultivation generally uses scallop cages. Seed oysters without a fixed base or those fixed on shells together with the shells are loaded into scallop cages and suspended for cultivation on floating ropes.

[0003] Due to the relatively large coastal winds and waves in China, under the impact of the winds and waves, the sharp edges of the oyster shells are likely to cut through the cages, causing losses and increasing the cultivation cost.

[0004] During the oyster cultivation process, seedling sorting or cage inversion is required. The existing cages are sealed with ropes. The ropes are similar in color to the cages and have a lot of attachments, resulting in difficulty in finding the cage openings. Two people are needed to rotate the cages to find the openings, which consumes a great deal of labor and time costs.

[0005] In different sea areas, the cultivation water layer of the cultivation cages should be appropriately adjusted according to seasons, water temperature, attached biological groups, etc. Usually, the water layer is maintained at 0.5m - 1.0m. During the high-temperature period and the season when a large number of marine organisms attach, it should be appropriately adjusted to a deep water layer of 0.5m - 4.0m. Currently, the depth of the cage placement depends on manual estimation, which is not accurate enough and affects the growth rate of oysters. Content of the Utility Model

[0006] The purpose of the utility model is to provide a new type of oyster cultivation cage for the above problems existing in the prior art.

[0007] To achieve the above object, the utility model adopts the following technical solutions:
