A method for cultivating oysters on a sea raft with a hard attachment base

Abstract

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...
