[0002] Oysters are cultured in the open sea far from the coast. Due to the strong wind and waves and the long duration, the oyster culture cages in the seawater are constantly shaking, so that the oysters in the culture cages and the culture cages are constantly rubbing against each other, resulting in the newly grown shells of the oysters. It is knocked off or ground flat, affecting the normal growth of oysters, and the oysters do not grow or grow slowly

Embodiment 1
[0015]The present invention is exactly to be attached with the scallop shell 4 of oyster seed on hard attachment bases 2 such as wooden stick or bamboo pole, hard plastic pipe, PVC pipe, begins to use rubber band 3 to band the scallop shell 4 of oyster seed Bound on the attachment base 2, along with the growth of the oyster, the oyster itself can secrete mucus and be fixed on the attachment base 2, and the attachment base 2 replaces the culture cage and the sling, eliminating the unfavorable factors of using the culture cage and the sling. The attachment base 2 is tied to the raft rope 10 of the raft culture, and the scallop shell 4 attached to the oyster seedlings is fixed on the attachment base 2. The new shell is not knocked off, and the oyster can grow normally, and the attachment base 2 is tied on the raft rope 10 as a culture cage, and the oyster seed is fixed on the attachment base 2 and feeds and grows; as the oyster grows up, the weight increases, and the hard Quality...

The invention provides a method for seaborne raft oyster culture through a hard substratum. According to the technical scheme, a circular hole (1) is formed in the upper portion of the substratum (2),grooves are formed in the outer layer of the substratum (2) at equal intervals, and scallop shells (4) are fixed to the grooves (5) through rubber bands (3); an ocean pasture oyster culture device ismainly composed of deepwater net boxes (6), a mooring rope (8), a raft rope (10), the substratum (2) and dropstone (11), connecting rings (7) are fixed to the two ends of the mooring rope (8), and the four deepwater net boxes (6) are connected through the mooring rope (8) to form a square. The method has the advantages that the scallop shells with oyster seedlings are fixed to the hard substratum, and healthy oyster growth is ensured; ocean current impact is lowered, the ocean oyster culture risk is lowered, the off-bank open sea space is expanded through the oyster culture method, and oysterculture in marine ranching and off-bank sea areas can be achieved.
Description
technical field [0001] The invention relates to the technical field of sea area cultivation, in particular to a method for cultivating oysters on a sea raft with a hard attachment base. Background technique [0002] Oysters are cultured in the open sea far from the coast. Due to the strong wind and waves and the long duration, the oyster culture cages in the seawater are constantly shaking, so that the oysters in the culture cages and the culture cages are constantly rubbing against each other, resulting in the newly grown shells of the oysters. If it is knocked off or ground flat, it will affect the normal growth of oysters, and the oysters will not grow or grow slowly. If the oysters are cultured attached to the rope, due to the effect of the wind and waves, the oysters will fall off the attached rope and fall into the sea, resulting in failure of cultivation and serious economic losses to farmers. Generally, oysters are cultivated in sea cages. Or slings, so that oysters...
