Description
Technical field
The present invention relates to a kind of net cage for sea farming, particularly a kind of fish culture net cage for cultivating left-eyed flounder.
Background technology
Left-eyed flounder is the large class of one in fish, and comprise the fish of Bothidae, Pangasiidae, Soleidae, be the demersal fishes that economic worth is higher, the demand of domestic and international market is larger.In recent years, a collection of high-quality left-eyed flounders such as turbot, lefteye flounder, Cynoglossus semilaevis are nutritious with it, mouthfeel good, it is high to be worth and cater to consumer market demand, and the aquaculture industry development of left-eyed flounder grows.
But end habit of dwelling because left-eyed flounder is distinctive and the very easily abrasive feature of body surface, the technology of cage culture left-eyed flounder fails to be well solved, and therefore, the cultivation of left-eyed flounder always is with batch production and Chi Yangwei master always.But the bottleneck problem of the restriction industry developments such as in recent years, along with the development of industry, left-eyed flounder land-base cultivation also faces littoral cultivation land used limited space, groundwater resources utilize excessively, unstable product quality.And cage culture, relative to batch production and pond culture pattern, there is the advantages such as aquaculture cost is low, fast growth, breeding environment are excellent, quality of fish is good.Therefore, develop the extraordinary net cage for left-eyed flounder cultivation, make full use of the natural marine site condition of the length and breadth of land, produce left-eyed flounder product that is best in quality, quality safety with more economic aquaculture model, the development promoting left-eyed flounder aquaculture industry is had great importance.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of single-point anchoring type left-eyed flounder fish culture net cage, to reach the safe handling that can ensure flounder flounder net cage, the object of the problems such as existing net cage poor stability, cost are high, complex operation can be solved again.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of single-point anchoring type left-eyed flounder fish culture net cage, comprise main body frame, the etting tied on described main body frame, heavy stone, hawser and mooring system, described main body frame is the rectangular structure that pipe fitting connects, heavy stone is connected by lifting rope bottom described main body frame, described mooring system is single point mooring system, the anchor chain comprise demersal anchor, connecting described hawser and anchor and the ball float of bubbling through the water column.
Preferably, described pipe fitting is hdpe pipe, adopts galvanized steel welding in the junction of described pipe fitting.
Preferably, described heavy stone hangs on described net cage bottom center by four isometric lifting ropes, makes net cage more stable in water, is conducive to reaching poised state.
Preferably, the height of described main body frame is 4.5m, and bottom side length is 7m × 7m, and the volume of whole net cage is about 100m
3.
Preferably, described anchor is the concrete gravity anchor of 5000kg, is fixed on seabed.
Pass through technique scheme, single-point anchoring type left-eyed flounder fish culture net cage provided by the invention can improve current exchange efficiency inside and outside net cage compared with the net cage of other type, thus effectively oxygen supply in increase net cage, when increasing fish culture density, negative effect be there is no to fish growth and health.Secondly, single point mooring system of the present invention can make net cage drift about with water (flow) direction, can alleviate the stress of marine environment load to anchoring by reducing lifting surface area.And rectangular structure of the present invention, net cage bottom framework and upper frame can be made to connect as one, thus improve the balanced capacity bottom net cage, safe and reliable platform can be provided for the growth of left-eyed flounder.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
Fig. 1 is the structural representation of a kind of single-point anchoring type left-eyed flounder fish culture net cage disclosed in the embodiment of the present invention;
Fig. 2 is the single point mooring system structural representation disclosed in the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
The invention provides a kind of single-point anchoring type left-eyed flounder fish culture net cage, structure as shown in Figure 1, this net cage can provide safe and reliable platform for left-eyed flounder growth.
Single-point anchoring type left-eyed flounder fish culture net cage as depicted in figs. 1 and 2, comprise main body frame, the etting 2 tied on main body frame, heavy stone 6, hawser 8 and mooring system, main body frame is the rectangular structure that pipe fitting connects, comprise upper frame 1, bottom framework 4 and munnion frame 3, be hdpe pipe to connect, adopt galvanized steel welding in the junction of pipe fitting, ensure the stability bottom net cage.The height of main body frame is 4.5m, and bottom framework is 7m × 7m, and the volume of whole net cage is about 100m
3, the design cultivation density of net cage can reach 60kg/m
3, actual cultivation density is about 20kg/m
3.
Connect heavy stone 6 by four isometric lifting ropes 5 bottom main body frame, carry out control subject framework by the weight changing heavy stone 6 and be immersed in the water wholly or in part, increase or reduce the buoyancy of net cage overall system, thus make the upper frame of net cage be positioned at the above position of the water surface.
Mooring system is single point mooring system, and the anchor chain 9 comprising demersal anchor 10, connection cable 8 and anchor 10 and ball float 7, two pairs of hawsers 8 of bubbling through the water column connect upper frame 1 and bottom framework 4 respectively, are then connected with anchor chain 9, and upper end connects ball float 7.Anchor 10 is the concrete gravity anchor of 5000kg, is fixed on seabed.Single point mooring system can make net cage drift about with water (flow) direction, effectively can overcome the impact of ocean current on cage structure, alleviates the stress of marine environment load to mooring system.
Single-point anchoring type left-eyed flounder fish culture net cage provided by the invention can improve current exchange efficiency inside and outside net cage compared with the net cage of other type, thus effectively oxygen supply in increase net cage, when increasing fish culture density, negative effect be there is no to fish growth and health.Secondly, single point mooring system of the present invention can make net cage drift about with water (flow) direction, can alleviate the stress of marine environment load to anchoring by reducing lifting surface area.And rectangular structure of the present invention, net cage bottom framework and upper frame can be made to connect as one, thus improve the balanced capacity bottom net cage, safe and reliable platform can be provided for left-eyed flounder growth.
