Wind-and-wave-resistant pearl oyster farming device and lifting type ecological farming method using same

Abstract

The invention relates to a wind-and-wave-resistant pearl oyster farming device and a lifting type ecological farming method using the same. The wind-and-wave-resistant pearl oyster farming device comprises a farming raft and a foundation framework which is used for carrying the farming raft and can regulate the underwater penetration of the farming raft, wherein the farming raft comprises a plurality of floating ropes and oyster containing net cages which are respectively connected below the corresponding floating ropes and form an integrated extension rope clamping cage with all the floating ropes, the farming raft is connected on the foundation framework through the floating ropes, and the underwater penetration of the oyster arranging net cage can be further regulated by regulating the vertical lifting positions of the floating ropes on the foundation framework. As the farming raft comprises the plurality of the floating ropes, the integrated oyster arranging net cage formed with the floating ropes and the like and the farming rapt is connected on the foundation framework in a manner of being capable of regulating the underwater penetration, when the farming raft is used, a farming water layer can be flexibly regulated, then the wind-and-wave-resistant pearl oyster farming device can facilitate production operation and be conductive to creating an artificial ecological environment for farming the oysters and growing cultured pearls, and production and economic losses caused by typhoons can be further avoided.

Description

[0001] technical field [0002] The invention relates to the field of aquaculture, in particular to a wind and wave-resistant pearl oyster cultivation device and a method for lifting and lowering ecological cultivation thereof. Background technique [0003] In domestic and foreign pearl cultivation, the methods of raising pearl oysters (such as mother-of-pearl oyster and pearl oyster) can be roughly divided into three types: [0004] 1. Piling farming method [0005] Use wooden or cement pillars to directly drive pilings on the seabed, the number of pilings varies, pull the rope horizontally and vertically, and hang the shellfish cages to raise shellfish and raise pearls. [0006] 2. Caisson culture method [0007] Put the shellfish in the net cage and try to fix them after sinking to the bottom of the sea, so as to raise shellfish and raise pearls. [0008] 3. Floating raft culture method [0009] With the way of anchoring or piling, 4 main fixed anchor points are set o...

Problems solved by technology

[0010] The above breeding methods: the first one has to wait for the low tide to see the piles, which is not convenient for production operations; the second one is cultivated at the bottom for a long time, and the bait organisms are insufficient, which is not conducive to the growth of shellfish; although the third one is easier to operate than the first two, However, the aquaculture rafts float on the water surface with the ebb and flow of the tide, and are easily affected by wind and waves, causing serious losses to production and the economy, and the aquaculture risk is high.

[0011] And most of these existing culture rafts are a plurality of independently cultured clam cages, one by one respectively by hooks or slings hanging on the same floating rope to cultivate the mode of raising pearls, because each cultured shellfish on the floating rope The cages are all independent rather than tightly connected together and then integrated with the floating rope, so it also greatly reduces its ability to resist wind and waves, and it is difficult to meet the requirements of the majority of farmers
