Description
Technical field
The invention belongs to aquaculture field, be specifically related to a kind of net cage used for aquiculture, the multi-layer aquaculture net cage that particularly a kind of safety is ecological.
Background technology
According to Historical Data Data About, China supported in by rivers the fry of fishing for temporarily with Dense mesh screen case before 800 years, support about 15 ~ 30 days time temporarily, etc. to be vended, this can regard as the blank of cage culture, but fish culture in net pen truly starts from 1973, object utilizes the primary producer of construction of reservoir (phytoplankton) and arranges net cage, cultivate the large gauge silver carp of more than 13 centimetres, Variegated, put in a suitable place to breed again in reservoir, to improve the survival rate of fingerling in reservoir, this intensive aquaculture model just obtains success very soon and promotes rapidly, the cage culture of China is started late, but it is reservoir, lake, the important channel of cultivating large area development.
Cage culture utilizes bamboo and wood, metal mesh sheet or synthetic fibers etc. as web pre fetching, be assembled into the case structure that definite shape is open, its etting part to be submerged completely in water and is strutted, space in etting is used for cultured fishes or shrimp, and by highdensity bait throwing in intensive culture, due to its economic benefits, make current cage culture more and more flourishing.Though current China net cage technique has large development, breed variety is also diversified, but also still there are some technical problems:
Chinese patent CN201595082U discloses a kind of Multi-layer solid mariculture net cage, it comprises the etting of framework and the case structure made with plank, framework passes through the buoys float of bottom on the water surface, the upper opening place of etting is fixed on framework, the bottom sides edge and each bar rib of surrounding of etting are all fixed with sinker, with make bottom etting sink and entirety strut, etting is provided with three layers, float is that density is less than the foam of water or seals empty bucket, although this device can allow different fish live in the most applicable water layer, and the waste of fish grain can be reduced when feeding, there is environmental pollution little, cultivation survival rate is high, the advantages such as opposing natural calamity ability is strong, but he adopts empty bucket, plank builds buoyancy and the supporting construction of net cage, the service life of this structure shorter and corrosion-vulnerable, larger threat can be caused to the safety of net cage and staff,
Chinese patent CN201319807 discloses a kind of big fixed net cage for cultivating seawater fishes, the pile of this net cage distributes along surrounding, pile outer cover etting surrounds case structure, etting is up and down respectively around the exaggerated and etting infraclass of etting, pile top is connected with oblique pull guiding principle II, pile top is connected with oblique pull guiding principle I, and the top of corresponding pile is connected by horizontal guiding principle.The utility model is by post of driving piles in seabed, and exaggerated, the infraclass that increase horizontal guiding principle, oblique pull guiding principle and etting fix large etting, expand the cultivation volume of net cage.Although the cultivation volume that it expands, owing to generally can only cultivate a kind of fish in a net cage, the fixing water layer and fish generally all live, therefore the change of increase to Fish Survival space of net cage height has little significance.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, the multi-layer aquaculture net cage that a kind of safety is ecological is provided, this net cage safety is high, there is significant economic benefit and environmental benefit.
Object of the present invention is achieved through the following technical solutions: the multi-layer aquaculture net cage that a kind of safety is ecological, it comprises internal layer net cage, middle level net cage and outer net cage, described internal layer net cage, middle level net cage and outer net cage are the upper shed casing that the etting that is fixed on boxed frame by boxed frame and edge is formed, middle level net cage is arranged at the inside of outer net cage, internal layer net cage is arranged at the inside of middle level net cage, all be connected by nylon rope between middle level net cage with outer net cage and between middle level net cage with internal layer net cage, the upper surface of outer net cage is provided with pedestrian's plate, the arranged beneath of pedestrian's plate has buoyant device, all bait table is furnished with in internal layer net cage and middle level net cage.
Described buoyant device is the airtight steel pipes in two ends, and the below of pedestrian's plate is evenly arranged the airtight steel pipe in multiple two ends.Described pedestrian's plate is reinforced concrete plate, and the top of pedestrian's plate is equipped with slipmat.
Described etting is polyethylene material.
The inside of described internal layer net cage forms fine work culture zone, forms economic culture zone, formed to mix and raise district scattered between middle level net cage with outer net cage between internal layer net cage and middle level net cage.
Described etting changes the different etting of mesh according to cultivation fry to the individuality change of adult fish.
The length of described internal layer net cage is respectively 5 ~ 6m, 5 ~ 6m, 3 ~ 5m, the length of middle level net cage is respectively 8 ~ 16m, 8 ~ 16m, 6 ~ 15m, the length of outer net cage is respectively 18 ~ 30m, 18 ~ 30m, 8 ~ 20m, and spacing distance >=1.5m between three-layer network case.
The present invention has the following advantages:
1. the present invention is mainly used in big lake cultivation, it is provided with three layer box body structures, different types of fish can be optionally cultivated in different housing area according to the kind of fish, habit of growth, economic benefit etc., overcome and solve the problem that cannot increase breed variety that conventional apparatus causes, the economic benefit of cultivation can be significantly improved;
2. because internal layer and outer net cage are provided with bait table, facilitate the feed of fish, the excreta that is interior, midwater fishes generation and the fish of outer cage culture can eat, therefore the waste of bait can not only be reduced, and it is little to water quality environmental pollution around, decrease the impact on lake ecosystem, more ecological, environmental protection;
3. net cage frame structure of the present invention adopts angle steel, channel-section steel, I-steel and steel pipe by being welded, the buoyant device in net cage region is the airtight steel pipes in two ends, the steel pipe adopting airtight two in two ends parallel is as connection device, the airtight steel pipe that between steel pipe, welding two is parallel in addition simultaneously makes it form the quadra structure of an equivalent specifications, the cement plank containing reinforcing bar is filled out in framework, Anti-slip ground cushion is established on its upper berth, both facilitated the management and maintenance work of staff, there is again longer and characteristic that is not corrosion-vulnerable in service life.
