Description
Technical field
The utility model belongs to hatching larvae servicing unit, more particularly to a kind of hatching larvae of Scylla paramamosain artificial breeding
Servicing unit.
Background technology
Scylla paramamosain（Scylla Paramamosain）Belong to Arthropoda（Arthropoda）, crustacean guiding principle
（Crustacea）, Decapoda（Decapoda）, Portumidae（Portunidae）, mud crab category（Scylla）, mainly divide in China
Be distributed in entrance of Changjiang River and on the south coastal marine site, be the important marine fishery resources in China and sea-farming crab class.
Scylla paramamosain has the characteristics of big build, growth fast, nutritious and delicious meat, is loved by people.In recent years
Come, China's Scylla paramamosain artificial farming yield is continuously increased, and keeps good growth momentum, is had very big development space and is supported
Grow potentiality.
With the continuous expansion of cultivation scale, the demand of Scylla paramamosain seed is also constantly rising.But artificial seed
Proportion is also very small in cultivation, is on the one hand due to also no very ripe, the opposing party of technology of mud crab artificial breeding
Face is that the cost of artificial breeding is higher.Every single stepping in artificial breeding may all influence whether seedling percent, so as to
Influence the success or failure of artificial breeding.One of problem is, in mud crab artificial breeding, the method for collecting the young mainly collects children
Method, but collect young method and collect young process complexity, it is necessary to parent crab to be produced be moved into row children in preprepared hatchery, then
It is transferred to after light trapping using diddle-net or wooden dipper in nursery pond, in the damage collected with the young is easily lead in transfer process
Wound, the health of the young may be influenceed, so as to cause the reduction of young survival rate.
The content of the invention
The purpose of this utility model is to provide a kind of hatching larvae servicing unit of Scylla paramamosain artificial breeding to solve
Collecting young method at present, to collect young process complicated, and collects process and easily cause mechanical damage to the young, so as to cause the young into
The more low problem of motility rate, cuts one another's throat to efficiently reduce parent crab, makes parent crab activity freer, reduces parent crab and the young
Damage, survival rate of seedling is improved, reduce seedling cost, meet the needs that artificial breeding is quick, simplicity collects the young, using as follows
Technical scheme：
A kind of hatching larvae servicing unit of Scylla paramamosain artificial breeding, mainly including steel wire frame（1）, etting（2）, Buddhist nun
Imperial lifting rope（3）And nylon cable tie（4）；The steel wire frame（1）Centre it is slightly convex；The etting（2）It is fixed on the steel
Reel frame（1）On；The nylon lifting rope（3）It is interspersed in the etting（2）The top；The nylon cable tie（4）Tie up described
Etting（2）And steel wire frame（1）Between and the etting（2）With nylon lifting rope（3）Between.Nylon lifting rope is used for whole device
Suspension and fixation；Nylon cable tie is used for the binding and fixation of etting.There is nylon lifting rope etting upper end, can hang on device
In nursery pond, and the height of suspension can be adjusted as needed；A parent crab is placed in each device, it is more free to give parent crab
Activity space, reduce cutting one another's throat between parent crab；After hatching larvae goes out, nursery pond water body can be directly entered by mesh.
Further, the steel wire frame includes multilayer wire loop（1-1）, vertical steel wire connection rod（1-2）And cross
Type steel wire rack（1-3）Composition；The multilayer wire loop（1-1）Rod is connected by the vertical steel wire（1-2）Connection；Described ten
Font steel wire rack（1-3）It is arranged on the wire loop of lowermost end（1-1）Inside.
Further, the wire loop（1-1）Rod is connected with the steel wire（1-2）And the wire loop（1-1）With institute
State cross-shaped steel guide frame（1-3）Point of intersection connected by welding.
Further, the wire loop（1-1）There are three layers, minimum, the middle wire loop of the diameter of the wire loop of lowermost end
Diameter it is maximum.
Further, the etting（2）Utilize the nylon cable tie（4）It is fixed on the steel wire frame（1）On；The Buddhist nun
Imperial lifting rope（3）For two, the etting（2）After flipping up, two nylon lifting ropes（3）Respectively from the left side in turnover space
End and right-hand member enter, and are intersected after being come out through etting from the other end, with the nylon cable tie（4）It is fixed.
Further, the etting（2）For 10 mesh ettings, it is made of polythene material.
Further, shown etting（2）Length is longer than the steel wire frame（1）.
Compared with prior art, the utility model is fixed using nylon rope, can hang on device in nursery pond, and energy
The height of regulation suspension as needed；Parent crab is placed in each device, gives parent crab more free activity space, reduces parent
Cutting one another's throat between crab；After hatching larvae goes out, nursery pond water body can be directly entered by mesh, makes parent crab activity more certainly
By that can play and ensure young quantity, reduce parent crab and young damage, improve survival rate of seedling, reduce the effect of seedling cost.
Realize parent crab and hatch the young in nursery pond.
