Abstract
The invention provides a large-scale large yellow croaker culturing device for high seas and deep seas, which comprises at least three buoys, wherein the buoys are connected with each other through purse nets so as to form a sealed culturing area, wherein the purse nets are formed by connecting net pieces in sequence; ropes are respectively arranged at the upper ends and the lower ends of the purse nets; floaters are arranged at the upper ends of the purse nets; net weights capable of enabling the lower ends of the purse nets to sink into sludge are arranged at the lower ends of the purse nets; the purse nets are expanded to form net walls, so that a bottomless culturing device is formed; sinking piles are arranged outside the purse nets at intervals; and the purse nets are connected and matched with the sinking piles through connecting ropes. The large-scale large yellow croaker culturing device has the advantages of strong wave resistance, large unit culturing area and convenience for placing and recycling; through the adoption of natural resources in the deep sea, artificially cultured large yellow croakers are acclimatized, so that meat qualities and mouth feels of the large yellow croakers are closer to those of wild large yellow croakers; therefore, the economic values of the artificial large yellow croakers are increased.
Description
Technical field
The present invention relates to technical field of aquaculture, the especially cultivator of large yellow Crocker, specifically, is a kind of scale Deepwater Open Sea marine site large yellow Crocker cultivator.
Background technology
Large yellow Crocker, belongs to Sciaenidae, yellow croaker genus, is commonly called as yellow croaker, yellow croaker etc., is water warm mass migration fish, and four famous Large Marine Ecosystem of Zeng Shi China are fished for one of object, and its body colour is golden yellow, delicious flavour, is described as " four large Chinese carps ".Along with the overfishing at the beginning of the seventies in last century, resource is seriously damaged, and cannot recover so far, can not form population.The wild large yellow Crocker that can catch is now very rare, expensive.Start the eighties, people constantly make up the demand to large yellow Crocker by the way of propagating artificially, but seawater cage culture is because of the restriction of the capacity of anti-storm of facility, can only the phytal zone in coastal harbour carry out and net cage monomer area little, water body exchange is poor, cultivation density is large, the yellow croaker body colour that causes forming, bar shaped, mouthfeel etc. all with wild yellow croaker cannot compared with, thereby be worth also not high.And by " deep water mesh cage " of extensive introducing and employment although monomer net cage supports area to increase to some extent, wind wave resistance performance increases, net cage monomer area is still limited, does not break through thousand square metres.
Existing publication number is the deep-water netted case resisting wind and wave that patent that CN1393125 name is called " deep-water netted case resisting wind and wave " discloses the adjustable workbench of a kind of buoyancy, buoyancy ring and sinker; Separately have publication number by the patent that CN1568675 name is called " submersible type deepwater net cage " a kind of cylindrical tubing, intermediate connector are disclosed, be equipped with strengthen rope netting gear and vertical orientated balancing weight and air inlet system and exhaust system formed submersible type deepwater net cage, complex structure relatively, operational administrative difficulty, cost is high, popularization is difficult, finally cannot effectively realize and improve the target of forming quality of large yellow croaker.
Summary of the invention
Technical problem to be solved by this invention is for the above-mentioned state of the art, provides wind wave resistance strong, and cultured area is large, and monomer cultured area can reach hundreds of thousands square metre, and places, reclaims a kind of scale Deepwater Open Sea marine site large yellow Crocker cultivator easily.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind of scale Deepwater Open Sea marine site large yellow Crocker cultivator; include at least three floating drums; between floating drum, be connected to form the culturing area of sealing by purse seine; wherein; purse seine is connected and composed successively by net sheet; the top and bottom of purse seine are respectively arranged with hawser; the upper end of purse seine is provided with float; and the lower end of purse seine is provided with and can makes the lower end of purse seine be absorbed in the net pendant in mud; purse seine opens formation leader and forms bottomless cultivator; purse seine is arranged at intervals with pile sinking outward, and purse seine is connected and matches with pile sinking by connection cord.
For optimizing technique scheme, the concrete measure of taking also comprises:
Above-mentioned purse seine is double-decker, and purse seine includes external network and interior purse seine, and the upper end of external network is provided with cover net foam plastic float, and the upper end of interior purse seine is provided with string hole foamed float.
Above-mentioned cover net foam plastic float includes cover net and foam plastic float, and foam plastic float is loaded in cover net successively, ties up the rope that is useful on insulation foam float between adjacent foam plastic float, and cover net foam plastic float matches with wire binding.
Above-mentioned string hole foamed float includes foamed float, and foamed float is placed through in steel wire successively, between adjacent foamed float, is provided with tie string, and tie string is tied up and matched with the upper end of interior purse seine.
Above-mentioned steel wire is wrapped with palm layer.
The height of above-mentioned purse seine is higher than 1.2 times～1.5 times of marine site highest water level.
Above-mentioned floating drum is connected and matches with spud pile by cable wire.
Above-mentioned spud pile is fixed on seabed or shore reef.
The lower end of above-mentioned floating drum is provided with the cement heavy stone used as an anchor that increases stability.
Above-mentioned net pendant, for anchor chain, is the plummet hanging with for increasing weight on anchor chain.
Compared with prior art; a kind of scale Deepwater Open Sea of the present invention marine site large yellow Crocker cultivator; include at least three floating drums; between floating drum, be connected to form the culturing area of sealing by purse seine; wherein; purse seine is connected and composed successively by net sheet; the top and bottom of purse seine are respectively arranged with hawser; the upper end of purse seine is provided with float; and the lower end of purse seine is provided with and can makes the lower end of purse seine be absorbed in the net pendant in mud; purse seine opens formation leader and forms bottomless cultivator, and purse seine is arranged at intervals with pile sinking outward, and purse seine is connected and matches with pile sinking by connection cord.Cultivator of the present invention adopts the steel wire of soft purse seine and rigidity to combine, in forming culturing area, guarantee the stability of purse seine, the present invention surrounds the culturing area of sealing at deep water sea area with purse seine, and keep culturing area relatively stable with floating drum, purse seine utilizes the effect of the buoyancy of float of upper end and the gravity of the net of lower end pendant to open formation leader, float is bubbled through the water column upper, and net pendant sinks in the mud in seabed, and this cultivator is without bottom structure.Purse seine adopts the double-decker of external network and interior purse seine, can farthest reduce because of the damaged risk that causes fish to run away of purse seine, and the height of etting is higher than 1.2 times～1.5 times of marine site highest water level, can avoid thoroughly not causing the loss of fish because flood tide causes purse seine interception; Steel wire is wrapped with palm layer, can avoid steel wire by the too fast corrosion of seawater, thereby improves the service life of cultivator.Cultivator wind wave resistance of the present invention is strong, and cultivation scope is large, and it is convenient to place, reclaim, and is suitable for different waters, varying environment situation.
