Description
Technical field
The present invention relates to a kind of oyster culture method.
Background technology
Aquaculture is the activity in production of breeding under manual control, cultivation and results aquatic animals and plants.Generally comprise the overall process of forming aquatic products under artificial feeding management from seed.Broadly also can comprise Enhancement of fishery resources.Aquaculture has the modes such as extensive cultivation, intensive culture and high density culture.Extensive cultivation is to throw in seed in medium and small natural water area, forms aquatic products completely by natural bait, as lake and reservoir, breeds fish and supports shellfish etc. with shallow sea.Intensive culture is with bait throwing in, fertilizing method, to form aquatic products in less water body, as aqiuculrue, fish culture in net pen and enclosure culture, net enclosure culture etc.High density culture adopts flowing water, temperature control, oxygenation and the methods such as high-quality bait of throwing something and feeding, and carries out high-density breeding in little water body, thereby obtains high yield, as Running Water Intensive Fish Farming, shrimp etc.Oyster is subordinate to Mollusca, lamellibranchiata, Ostreidae.Be coastal the most common bivalve shellfish, of a great variety, it is said that there is kind more than 100 in the whole world, China has reported kind more than 20.Propagate artificially is mainly following 4 kinds: i.e. Crassostrea rivularis, pleat oyster, close squama oyster and long oyster.Now the cultural technique of long oyster is described below: long oyster also claims true oyster, Japan real oyster, and Pacific oyster natural distribution is coastal in Japanese continent, Hokkaido to nine.It is the euryhalinous inner bay shellfish of a kind of wide temperature.It is attached to reveals on empty rock or building at ebb tide.China introduced cultivation from 1979.
Summary of the invention
The object of the present invention is to provide a kind of oyster culture method, have physique stalwartness, individual large, spatfall evenly, the feature such as fast of growing.
Technical scheme of the present invention is: a kind of oyster culture method, comprises the following steps:
(1) place is selected: substrate is advisable with mud or argillo arenaceous, and the depth of water is more than 1.3 meters, and per day rate of water exchange should reach 50% left and right. and early stage, transparency should be controlled at 40～50 centimetres, and the middle and later periods is controlled at 50～60 centimetres;
(2) site preparation: before seed is put in a suitable place to breed, thorough desilting, by playing leveling compacting at the bottom of the pond at oyster seed place, be dimpling shape with instruments such as bulldozers, a little more than bottom surface around, can sink be buried by mud lethal by anti-oyster seedling;
(3) broadcast seedling season: generally in the middle ten days in March to mid-April, broadcast seedling comparatively suitable, in production, can broadcast in mid-May seedling at the latest;
(4) broadcast seedling: guaranteeing under normal prawn breeding density prerequisite, the amount of supporting of broadcasting of oyster seed is advisable with every 667 square metres of 30,000 left and right, broadcast at the beginning of the seedling time should be chosen in 4 months, seedling seeded player specification with shell long 2 centimetres above for well, broadcast seedling stress equilibrium, and avoid the low-lying Chu He bait throwing in of circular groove district, broadcast seedling area and account for 1/4～1/ of pond floor space.
A kind of oyster culture method of the present invention, have physique stalwartness, individual large, spatfall evenly, the feature such as fast of growing.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic flow sheet of oyster culture method one preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, Fig. 1 is a kind of oyster culture method of the present invention, comprises the following steps:
(1) place is selected: substrate is advisable with mud or argillo arenaceous, and the depth of water is more than 1.3 meters, and per day rate of water exchange should reach 50% left and right. and early stage, transparency should be controlled at 40～50 centimetres, and the middle and later periods is controlled at 50～60 centimetres;
(2) site preparation: before seed is put in a suitable place to breed, thorough desilting, by playing leveling compacting at the bottom of the pond at oyster seed place, be dimpling shape with instruments such as bulldozers, a little more than bottom surface around, can sink be buried by mud lethal by anti-oyster seedling;
(3) broadcast seedling season: generally in the middle ten days in March to mid-April, broadcast seedling comparatively suitable, in production, can broadcast in mid-May seedling at the latest;
(4) broadcast seedling: guaranteeing under normal prawn breeding density prerequisite, the amount of supporting of broadcasting of oyster seed is advisable with every 667 square metres of 30,000 left and right, broadcast at the beginning of the seedling time should be chosen in 4 months, seedling seeded player specification with shell long 2 centimetres above for well, broadcast seedling stress equilibrium, and avoid the low-lying Chu He bait throwing in of circular groove district, broadcast seedling area and account for 1/4～1/ of pond floor space.
Further illustrate, oyster seedling, after the cultivation of 3～4 months, should carry out " deeply moving rare supporting " early, exactly the intensive concrete column migration low tidal region in the district of collecting seedling is carried out to sparse cultivation, to extend its ingest time, obtains sufficient bait; Meanwhile, for collecting seedling next year, vacate vacant lot.Early move and slow phase shift ratio, early move the growth of oyster seedling fast, individual large, meat is fertile, moves then foster oyster October and moves foster comparing April in next year, output can increase by 30% left and right.Oyster results are fattened the concrete column of the forming district shale seabeach that migration water quality is fertile again, flow velocity is larger in first 5～6 months, and this is the effective measures that improve oyster Quality and yield., full grains dense through the thick look of oyster shell of fattening, specific yield can double left and right.For ease of operational administrative, the spread pattern of concrete column is with " individual plant straight cutting " for well, and the transfer between two strains is that 40 centimetres, advance are 70 centimetres, every 4 behavior one communities, and the distance between each community is 4 meters.Meanwhile, slotting concrete column requires anyhow neat, enters mud firm, and trend is unobstructed, is convenient to ship current.Management between will strengthening during oyster culture being coated with, tilts if there is concrete column, and righting in time or mention heavily slottingly and is removed the mud being attached on oyster shell, the algae of mixing, and it is returned to normal production.Meanwhile, keep a close eye on Changes in weather, as summer and autumn typhoon, heavy rain often large quantities of concrete columns can be washed upside down, oyster is poached and suffocates, therefore to assault lower painting repairing oyster beach, hold up the concrete column of straight lodging, to reduce casualty loss.In addition, also will remove various harmful organisms, as carnivority fish such as ray, Japanese seaperch, available fishing tackle hook is caught or at things such as the soft bamboo of its discrepancy place cuttage, branches, the sound that the vibrations of nationality trend are sent is drawn back with fear; Also have various snails, as dog whelk, red spiral shell, the beautiful spiral shell of spot etc., it mainly eats the young oyster of evil, can contain the phase assault of sending out at it and catches or root out together with ovum group.The invention provides a kind of oyster culture method, have physique stalwartness, individual large, spatfall evenly, the feature such as fast of growing.
