Problems solved by technology

[0005] The purpose of the present invention is to solve the problem of wind and wave resistance of culture facilities and cultured pearl oysters by adopting simple technical measures in view of the deficiencies of the current seawater pearl oyster cultivation methods and the development trend of the culture sea area from the near-shore shallow water area to the deep water area above 20 to 30 meters, and improve the Aquaculture facilities and the ability of cultured pearl oysters to resist strong winds and waves, and avoid economic losses caused by typhoon-induced destruction of aquaculture facilities or broken suspension ropes

Embodiment 1

[0026] 1. Preparatory work: Prepare various ropes, floating balls and anchors; make sliding rings, positioning blocks, and cement sinkers.

[0027] 2. Set a series of floats 1 arranged in a straight line every 5-10m on the water surface. The floats 1 are connected by fixed ropes 8 .

[0028] 3. Connect the cement sinker 3 to one end of the dry rope 2, then fix the positioning block 7 about 5m away from the sinker 3, and sink the sinker 3 into the seabed at the position of the float.

[0029] 4. Connect a lifting rope 6 to each sliding ring 4, and fix the lifting rope 6 on the buoy 1 or the fixed rope 8 between the buoys 1.

[0030] 5. Pass the water surface end of the dry rope 2 through the sliding ring 4, and each dry rope 2 passes through a sliding ring 4, and then connect the dry rope 2 with the buoy 1.

[0031] 6. Connect the adjacent sliding rings 4 with the long rope 5, pull the lifting rope 6 upward to lift the whole long rope 5 to the water surface and fix it to the f...

Embodiment 2

[0035] 1. Preparation: Prepare various ropes and stakes; make sliding rings and positioning blocks; fix the positioning blocks at a position about 5m away from the lower end of the stakes.

[0036] 2. Set up a series of wooden stakes in a straight line every 5-10m in the water.

[0037] 3. Connect a lifting rope 6 to each sliding ring 4, put the sliding ring 4 in the wooden pile, and fix the lifting rope 6 on the water surface part of the wooden pile.

[0038] 4. The wooden stakes are connected with fixed ropes 8 on the water surface, and the two ends are fixed on the anchor fixtures 10 on the seabed through anchor ropes 9 .

[0039] 5. Connect the adjacent sliding rings 4 with the longline 5, pull the lifting rope 6 upward to raise the whole longline 5 to the water surface and fix it to the fixed rope 8 between the wooden stakes on the water surface; the pearl oyster is hung on the longline 5 on.

[0040] 6. When the typhoon comes, loosen the lifting rope 6 fixed on the fix...

Abstract

The invention relates to a lift long line windproof culturing method of pearl shell. A series of upright main lines are fixed by floats and weights in the culturing area and slip rings are arranged on the main lines. The slip rings are connected with each other by long lines and a pull rope is arranged on the slip ring. The whole pull rope and the pearl shells cultured on the pull rope can be risen or dropped under the action of pulling the pull rope upwards or the gravity actions of slip rings, pull rope and the pearl shells cultured on the pull rope. The windproof function can be achieved when the long lines drop down to the underlayer of the water body and the culturing management operations can be carried out when the long lines rise up to the surface layer of the water body.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating pearl oysters with a liftable longline against wind and waves. Background technique [0002] Seawater pearl farming is an important industry in the field of aquaculture in my country. The main production areas of seawater pearls in my country are Leizhou Peninsula in Zhanjiang City, Guangdong Province, Hepu in Beihai City in Guangxi Province and Sanya in Hainan Province. Zhanjiang City is the most important seawater pearl industry. Pearl producing areas, its output accounts for about 70% of the country's total output. At present, the vast majority of seawater pearl culture sea areas in my country are inshore sea areas with a water depth of 10 meters. The existing pearl oyster artificial culture methods include pile culture method, raft culture method, and float longline culture method. The pile culture method is to plant wooden piles or cement piles a...
