Description
Technical field
The invention belongs to oyster young enhancement releasing technical field, particularly relate to a kind of littoral zone marine site oyster young enhancement releasing
Adhesive substrate device and construction method.
Background technology
Oyster is the zoobenthos of a kind of plankton feeding habit, in attached type, clustering life, its constitute oyster bioherm ecosystem
System has important ecological functions and value, at water body purification, perches habitat composition, bio-diversity conservation, stablizes seashore
Line and the aspect such as substrate and promotion Cycle of nutrients are respectively provided with highly important effect, are enhancement releasing and restoration of the ecosystem neck
Kind that what territory was good release.Along with the heavy damage of mankind's activity oyster bioherm original to littoral zone system, China or even in the world
Littoral zone or bay oyster bioherm habitat the most in various degree by environmental pollution, the engineering activity such as enclose and cultivate and gradually disappear,
So that river mouth or the aggravation of littoral zone Eutrophic Extent, the forfeiture of fishery production rapid decrease, ecosystem function, therefore
How to recover and improve function and the structure of the littoral zone ecosystem, improve fish production power, become current people and urgently solve
A difficult problem and hot issue.
At present, both at home and abroad for the fishery kind enhancement releasing in littoral zone or bay carry out more, mainly have Chinese prawn,
Swimming crab, razor clam of hanging, blood clam, clam, large yellow croaker etc., these kinds of releasing all need not build adhesive substrate, and the oyster young
Enhancement releasing then have to build suitable adhesive substrate facility and provide good habitat for its growth and breeding.General in river mouth
Or littoral zone, sedimentation speed is relatively big, if the silt suspended in water deposits at oyster adhesive substrate, then can bury oyster children
Body make its can not normal growth and breathing and cause the death of oyster, it is therefore desirable to design a kind of new oyster young adhesive substrate dress
Put with enhancement releasing construction method to solve this difficult problem.It addition, traditional shed frame type hanging culture oyster technology is usually between tide
Band low tidal region is carried out, it is difficult to carry out enhancement releasing in subtidal zone profundal zone, required cost is the most of a relatively high.Littoral zone sea simultaneously
Territory is relatively big due to tidal current speed, and position, suitable marine site is chosen and become for oyster enhancement releasing with oyster adhesive substrate installation method
Merit is also one of important factor in order.Accordingly, it would be desirable to redesign one can carry out the oyster young in littoral zone deeper water
The adhesive substrate device of enhancement releasing and making and construction method.
Summary of the invention
The technical problem to be solved is to provide a kind of littoral zone marine site oyster young enhancement releasing adhesive substrate device and structure
Construction method, it is possible to during the enhancement releasing for littoral zone oyster is repaired with marine ecosystem simple and practically, can be local simultaneously
The species diversity maintenance in marine site provides good facilitation.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of littoral zone marine site oyster young enhancement releasing
Adhesive substrate device, including adhesive substrate and hanging apparatus, described adhesive substrate includes two column floating drums and is embedded in the silt of seabed

B () avoids spring tide to carry out the installation of adhesive substrate and hanging apparatus flood season, the direction along trend fluctuation tide carries out adhesive substrate
Lay and the choosing of mao bamboon stake 64 position；
C () is filled 2 the strip mesh bag 5 of adult oyster shell in advance and is installed to rubber tyre in after cross combining
The inner ring of 1, forms the hanging apparatus of the combined type oyster young；
D single combined type oyster young hanging apparatus is connected on float 2 by () by thin nettle 3, described float 2 is through
On buoyant rope 4；
E the sowing of () oyster young is sowed on adhesive substrate device by artificial or natural marine site dish seedling mode；
F () installs mao bamboon stake 64 in seabed silt 67, and by rope sling 66, column floating drum 61 is fixed on mao bamboon stake 64
On；
Repeat step (c)～(f), required quantity is set according to oyster quantity.
Further illustrate below in conjunction with a specific embodiment:
The combined type adhesive substrate of the oyster young and the enhancement releasing reality of hanging apparatus has been carried out in littoral zone marine site, entrance of Changjiang River, the East Sea
Testing, the oyster kind released is pleat oyster, and this marine site sediment charge is relatively big, and stormy waves is the biggest.
First, rent fishing boat and carry out mao bamboon stake and the installment work of oval floating drum in suitable marine site, along trend ebb tide
A duck eye is respectively bored with giant in time interval 100m position, direction in seabed, it is simple to mao bamboon stake is imbedded in the silt of seabed smoothly,
Upper end in mao bamboon stake is opened a horizontal apertures and fastens rope sling in advance, rope sling be connected with vertical cord and pass through circular is connected ring and
Oval floating drum is connected.So, just defining adhesive substrate, repeat above-mentioned operating procedure, interval 10m carries out next solid
The installation of base.
Secondly, the hanging apparatus made in advance is transported appointment marine site by fishing boat.Fishing boat slow train top is flowed in fixed base
One end in two floating drums, by buoyant rope bolt on the connection ring of floating drum lower end, fishing boat slow train top stream slowly leaves for floating drum subsequently
The other end, the multiple hanging apparatus on ship are slowly thrown in water by period, until it reaches by buoyant rope and floating drum after other end floating drum
The connection ring bolt of lower end is tight.Complete the adhesive substrate of the single oyster young as shown in Figure 2 and the whole of hanging apparatus
Installment work.
Finally, repeat the installment work of adhesive substrate and hanging apparatus, just define 20 row's oyster young enhancement releasings
Adhesive substrate and hanging apparatus.Oyster biomass actual demand according to enhancement releasing arranges required adhesive substrate and hanging apparatus
Installation scale.
Time-consuming about 2 days of whole installment work, required labour about 10 person-times.The enhancement releasing time of oyster typically in spring 3～
April is carried out, and the beneficially natural spatfall of adhesive substrate is carried out, and can be greatly improved survival rate.In 6 months subsequently naturally growth,
The Individual Biomass of oyster improves about 30%.This kind of method has easy and simple to handle, easy-to-understand, success rate high,
Also there is in the enhancement releasing of other oyster kind the highest feasibility.
