Abstract

The invention discloses a reinforcement type wind wave resistant oyster cultivation method, which comprises the following steps: in a buoyant raft type hanging mode, firstly, clamping a scallop shell attached with an oyster juvenile mollusk in the screwing gap of a clamping rope; fixing the scallop shell onto the clamping rope by single strand of high-strength fish wire; according to the amount of the oyster larvae, fixing one scallop shell substratum at a certain fixed distance; and finally, hanging the clamping rope on a buoyant raft for cultivation. The reinforcement type wind wave oyster cultivation method has the advantages that the cultivated oyster is prevented from falling in the mode that the clamping rope used for the cultivation is thickened and the single strand of fish wire is used for reinforcement under the offshore cultivation environment of big wind wave, and yield loss caused by the wind wave is reduced. The operation method is simple and easy to realize, and has an important function on lowering the management cost in the oyster cultivation process and improving the oyster yield.

Description

A kind of reinforced wind wave resistance oyster culture method

Technical field

The invention belongs to the shellfish culture technical field, specifically a kind of reinforced wind wave resistance oyster culture method.

Background technology

Oyster belongs to the sessile form shellfish, no longer moves throughout one's life after relying on its left shell set, by the closure of its right shell, filters planktonic algae.Oyster is the important shellfish culture kind of China, and its output accounts for the 70-80% of whole mariculture output, is the source of a kind of good protein, zinc and taurine.

Oyster culture does not need artificial bait throwing in, a kind of typical carbon remittance type pollution-free industry, but due to the again planning of country to marine economy, the fast development of offshore eco-tourism, make the coastal waters cultured area significantly reduce, these factors make oyster culture from the offshore cultivation to bank cultivation development far away.According to the difference of mariculture area, the breeding way of oyster mainly is divided into three major types: mudflat aquaculture, fish-farming in shallow marine water and pond culture.At present, fish-farming in shallow marine water mode mainly is divided into floating raft type folder rope hanging culture and floating raft type is raised in cages two kinds.Floating raft type folder rope hanging culture is suitable for the sea area that the offshore stormy waves is little.The wave is high stream anxious marine site, this mode usually causes the underproduction of oyster culture.The raft formula is raised in cages and need to often be carried out attachment and minute cage processing of whole cage to remove the cage surface.In the situation that labour cost is growing, this makes the oyster culture cost increase, and, in breeding process, the secondary shell of oyster easily will cultivate the scallop cage of use and cut, and this has also increased cost from another point of view.

The utility model patents such as " the shellfish wind wave resistance hanging apparatus that a kind of degree of depth is adjustable " that a kind of " algae wind-wave resisting rope sinking type cultivation facility and the method " that application number is 200910018386.8, " Anti-wave soft rack abalone culture device ", the application number that application number is 201120065471.2 are 201020517268.X all is studied the cultivator of different marine prods, but relate to oyster wind wave resistance cultural technique, have not been reported.

Summary of the invention

The object of the present invention is to provide a kind of oyster culture method of energy wind wave resistance, under bank breeding environment far away, by the mode that cultivation is carried out overstriking and used sub-thread high-strength polyethylene fiber fishing line to reinforce the scallop shell adherance with the folder rope, guarantee that oyster culture is because stormy waves comes off, reduce the loss of cultured output.

The present invention is achieved by the following scheme: a kind of reinforced wind wave resistance oyster culture method, adopt floating raft type hanging culture mode, the scallop shell adherance that at first will be attached with the oyster juvenile mollusk is clipped in the stubborn seam of rope, with fishing line, by the hole on the scallop shell adherance, be fixed on the folder rope again, fix a scallop shell adherance according to spat of oyster amount every 12-15cm, finally pressing from both sides restricts to hang on buoyant raft is cultivated.

The scallop shell adherance is preferably the adherance of the middle with hole that chlamys farreri shell, bay scallop shell or Patinopecten yessoensis shell make.

The folder rope is preferably the bifilar or three-ply polythene rope of diameter 1-3 cm, length 2-4 m.

Fishing line is preferably sub-thread high-strength polyethylene fiber fishing line.

The invention has the advantages that: under the land wind breeding environment that the wave is high far away, by overstriking, cultivate with the folder rope and use the mode of sub-thread fishing line reinforcing can guarantee that oyster culture does not come off, improving output; Method of operating is simple, and can effectively reduce the management cost in the oyster culture process.

The accompanying drawing explanation

Fig. 1 is that the scallop shell adherance is fixed on the schematic diagram on the folder rope by the high strength fishing line.Wherein: 1 scallop shell, 2 folder ropes, 3 fishing lines.

Embodiment

Below in conjunction with the drawings and specific embodiments, the present invention will be further described.

Embodiment: as shown in Figure 1, a kind of reinforced wind wave resistance oyster culture method, at diameter 2 cm, on the bifilar polyethylene folder rope of long 3 m of rope, every 12cm, the one chlamys farreri shell adherance that is attached with the spat of oyster is clipped in stubborn seam, then it is upper to be fixed in the folder rope with sub-thread high-strength polyethylene fiber fishing line by the hole on scallop shell, will press from both sides restricts to hang on buoyant raft is cultivated.

Claims

1. a reinforced wind wave resistance oyster culture method, it is characterized in that: adopt floating raft type hanging culture mode, the scallop shell adherance that at first will be attached with the oyster juvenile mollusk is clipped in the stubborn seam of rope, with fishing line, by the hole on the scallop shell adherance, be fixed on the folder rope again, fix a scallop shell adherance according to spat of oyster amount every 12-15cm, finally pressing from both sides restricts to hang on buoyant raft is cultivated.

2. a kind of reinforced wind wave resistance oyster culture method as claimed in claim 1, is characterized in that the oyster young adherance that the scallop shell adherance is the middle with hole made of chlamys farreri shell, bay scallop shell or Patinopecten yessoensis shell.

3. a kind of reinforced wind wave resistance oyster culture method as claimed in claim 1, is characterized in that the folder rope is preferably the bifilar or three-ply polythene rope of diameter 1-3 cm, length 2-4 m.
