Description

Deep water three-dimensional culture primary and secondary net

Technical field

The utility model relates to a kind of deep water culture devices, and in particular to a kind of deep water three-dimensional culture primary and secondary net.

Background technique

Traditional aquaculture is mostly using single variety large-scale cultivation as Main Patterns, natural calamity, pest and disease damage, the market price Fluctuation all influences huge, the no three-dimensional application of breeding water body resource to it.And existing Polyculture is by the period of breed variety It limits, can not be widely applied with life habit.

Utility model content

The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, design is closed Reason, deep water three-dimensional culture primary and secondary net easy to use can be applied to fishing row, on current -resistance submerged cage.

To achieve the above object, the technical solution adopted in the utility model is：It includes net cage frame, female net, subnet, anchor Pier；The diameter of the subnet is less than the diameter of female net；Subnet is located at the middle inside of female net；Subnet, the top of female net are logical Net head fixed rope is crossed to connect with net cage frame；The bottom of subnet and female net is equipped with net bottom traction rope；The net bottom of subnet bottom is led Messenger passes through the bottom of female net, and connect after passing through anchor pier together with the net bottom traction rope of mother's net with the net cage frame on the water surface； Evenly distributed shellfish culture cage is hung on the outside of net cage frame；

Preferably, the net cage frame uses annular frame；

Preferably, the mesh specification of the subnet is less than the mesh specification of female net；

Preferably, the length of subnet and the net bottom traction rope of female sieve bottom is twice of the depth of water or more, convenient for draping and Receive fish.

After adopting the above structure, deep water three-dimensional culture primary and secondary net described in the utility model, is that one kind makes full use of space The scientific culture device of resource and the ecological chain relation of breed variety, it has the following advantages that：

It 1, can be by the cultivation of carnivorous and phytophagous kind in same water body, using food chain relation excitation both sides' vigor to increase Add water body oxygen dissolved, the bait residue and excreta of subnet can be digested by female netting class, play the effect of saving and environmental protection；

2, it is different from the mesh specification of mother's net to can use subnet, by fry and adult fish culture in same water body, to adult fish Intranet is unlocked after having sold, by subnet fish culture in mother's net, to reduce loss；

3, cultivation income not only can be improved in the shellfish of net cage frame periphery hanging culture, can also filter water body, reduces fish Pest and disease damage；

4, when cultivating high value carnivority kind, subnet can cultivate living body bait fish；

5, can be with intercropping scavenging kind (such as shrimp crab), it can be significantly as its bait using the fish corpse of female net natural selection Save the cost；

6, in water temperature extreme variation, mother can be netted to cultivation fish and be compressed on the more stable water layer of water temperature；

7, low manufacture cost, assembling simply, are preferably safeguarded, can be widely applied and apply.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, is also possible to obtain other drawings based on these drawings.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is top view when the utility model does not hang shellfish culture cage.

Description of symbols：

1, female net；2, subnet；3, shellfish culture cage；4, net cage frame；5, net bottom traction rope；6, anchor pier；7, net head is fixed Rope.

Specific embodiment

With reference to the accompanying drawing, the utility model is further described.

Referring to shown in Fig. 1-2, present embodiment the technical solution adopted is that：It includes net cage frame 4, female net 1, son Net 2, anchor pier 6；The diameter of the subnet 2 is less than the diameter of female net 1；The mesh specification of subnet 2 is less than the mesh rule of female net 1 Lattice；Subnet 2 is located at the middle inside of female net 1；Subnet 2, female net 1 top pass through net head fixed rope 7 and net cage frame 4 connects It connects；Net cage frame 4 uses annular frame；The bottom of subnet 2 and female net 1 is equipped with net bottom traction rope 5；The net bottom of 2 bottom of subnet Traction rope passes through the bottom of female net 1, and pass through together with the net bottom traction rope of female net 1 after anchor pier with the net cage frame 4 on the water surface Connection；The length of subnet and the net bottom traction rope 5 of female sieve bottom is twice of the depth of water or more, convenient for draping and receives fish；Net cage The outside of frame 4 is hung with the shellfish culture cage 3 of uniform intervals arrangement；When the suspension depth of shellfish culture cage 3 is with heeling condition Not contacting female net 1 is optimum depth.

In use, female net 1 is first entangled subnet 2 on continental rise, the net bottom traction rope of 2 bottom of subnet is in female 1 bottom of net Net bottom traction rope position passes through, and then the net bottom traction rope of subnet bottom and the net bottom traction rope of female sieve bottom are also cross anchor pier 6；Female net 1 and subnet 2 are transported to net cage frame 4, tied up the net head of subnet 2 and female net 1 in net cage frame by net head fixed rope 7 On 4, then by the investment suitable position of anchor pier 6, net bottom traction rope 5 is tensed to stablize subnet and female net dictyosome；Net bottom is unclamped when draping Traction rope 5.

The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope should all cover in the scope of the claims of the utility model.
