The present invention relates to a kind of method using the big oyster of suspended longline farming, comprise the following steps:1) 10~20 meters of the depth of water is selected, salinity is not less than 0.9%, and minimum water temperature is not less than 5 DEG C, and the offshore sea waters of the mg/litres of dissolved oxygen > 5 is mariculture area, and buoyant raft is built in mariculture area;2) immersed under buoyant raft with the attachment base of 1~4 meter of the big oyster oyster seedling of rope suspensions set, attachment base in a manner of interval is hung on rope in seawater;3) culturing time totally three years, from the hanging culture of a length of 10~20 millimeters big oyster oyster seedling of body during First Year, the marine site that buoyant raft is fixed on to salinity 0.9%~1.5% is cultivated, and during Second Year, buoyant raft transfer is fixed on into the marine site that salinity is 1.5%~2% and cultivated;At the 3rd year, the marine site that salinity is 2%~3% is fixed in buoyant raft transfer and cultivated, can be harvested after the body of big oyster is grown more than 10cm.This can not only provide the nutrient of abundance in breeding process for big oyster, additionally it is possible to reduce the destruction to environment.

Description

Utilize the method for the big oyster of suspended longline farming

Technical field

The present invention relates to field of marine product cultivation technology, has and is related to a kind of method using the big oyster of suspended longline farming.

Background technology

Big oyster, scientific name Crassostrea rivularis, it is one of marine products rare greatly of Qinzhou four, meat can be eaten raw, can also be processed into oyster Fermented soya beans, salted or other wise, oyster sauce.Big oyster oyster meat protein content is more than 40%, nutritious, delicious flavour, is known as the title of " marine milk ", simultaneously It can also be used as medicine.Qinzhou Wan Mao Weihai is national maximum big oyster natural seeding, wild fry breeding area, is famous " Chinese great Hao Zhi townshiies ", mesh The preceding coastal shoal in the whole city, which applies the slotting foster and big oyster area of deep water hanging culture, more than 140,000 mus, and the beach for being available for exploitation to cultivate has more than 130 Ten thousand mu.Traditional big oyster cultural method is column cultivation, needs during cultivation to build column, and investment is larger, and due to seawater tide The change of nighttide, the height of seawater also change, it is difficult to the nutrient of abundance are provided for big oyster, in addition, the easy heap of column set Rubbish when product mud and cultivation, is highly vulnerable to breakage environment.

The content of the invention

The technical problem to be solved in the present invention is to provide a kind of method using the big oyster of suspended longline farming, can not only cultivate Process provides the nutrient of abundance for big oyster, additionally it is possible to reduces the destruction to environment.

In order to solve the above technical problems, the present invention uses following technical scheme:

A kind of method using the big oyster of suspended longline farming, comprise the following steps:

1) 10~20 meters of the depth of water is selected, salinity is not less than 0.9%, and minimum water temperature is not less than 5 DEG C, the mg/litres of dissolved oxygen > 5 Offshore sea waters be mariculture area;Buoyant raft is built in mariculture area, buoyant raft fixes floatability using bamboo and wood as main body frame under bamboo and wood Thing, buoyant raft edge are drawn with hawser, and buoyant raft is fixed on sea by the water intake end connection anchor of hawser;

2) restricted under buoyant raft with the attachment base of 1~4 meter of the big oyster oyster seedling of rope suspensions set, attachment base with interval hanging Mode on rope is immersed in seawater, and 5~20 attachment bases, the distance of the attachment base of the top apart from sea are hung on every rope For 20~50cm, the spacing between adjacent attachment base is 2~20cm;

3) culturing time totally three years, from the hanging culture of a length of 10~20 millimeters big oyster oyster seedling of body during First Year, buoyant raft is consolidated Cultivated due to the marine site of salinity 0.9%~1.5%, during Second Year, buoyant raft transfer is fixed on salinity for 1.5%~2% Marine site cultivated;At the 3rd year, the marine site that salinity is 2%~3% is fixed in buoyant raft transfer and cultivated, treats big oyster Body length can harvest more than after 10cm.

In above-mentioned technical proposal:

The bamboo and wood is formed the main body frame of buoyant raft in the form of being built into square net, the specification of each grid for 20~ 50cm × 100~200cm.

The floatability thing is foam, tire or empty barrel.

The attachment base is stone, tile, ceramics, cement block or shell.

The mariculture area is preferably the marine site in the range of 0.5~5km of mangrove edge.

The amount of supporting of broadcasting of the big oyster oyster seedling is preferably 1~30,000/mu.

Beneficial effects of the present invention are:

The big oyster buoyant raft hanging culture of the present invention, big oyster fully can be soaked in seawater, and buoyant raft can enter as needed Row migration, can provide sufficient nutriment for the cultivation of big oyster, it is ensured that the Fast Growth of big oyster;And big oyster is to keep hanging on sea In water, substantial amounts of mud will not be produced because hindering tidal fluctuations, effect on environment is small.
