Abstract
The invention provides a high-density crab culture pond, aims to solve the problem of low density for crab culture in existing ponds, and relates to the technical field of aquaculture. A plurality of ridges are arranged in the pond to separate a water area in the pond into a continuous circular waterway, and an aerator is arranged at the bottom of the circular waterway and supplies power for water circulation. Compared with existing crab culture ponds, the crab culture pond has the advantages that the ridges are arranged in the pond, so that area suitable for crab culture in the pond is increased, and density for the crab culture in the pond is greatly increased by more than three times; the ridges separates the water area in the pond into the continuous waterway, so that water can flow, dissolved oxygen amount of the water can be increased and conditions for living habit of crabs can be satisfied; the ridges have small gradients, so that the crabs can be prevented from burrowing; the aerator aerates water underwater, so that the dissolved oxygen amount of the water can be increased and the water can be driven to flow.
Description
Technical field:
The present invention relates to technical field of aquaculture, relate in particular to a kind of high density crab cultivation and use the pond.
Background technology:
It is very high to the requirement of plant to propagate crab artificially, will quadrature and generally be advisable at 1-5 mu in the pond of culturing crab at present, and crab pond condition is had abundant water resources, and water quality is good, and Inlet and outlet water is convenient, the depth of water generally with 1-1.5 meters for well.Crab pond substrate amount is preferably sandy loam, gravel soil, and venting capability is good, is conducive to pasture and water, the end vegeto-animal growth and breeding of dwelling, and can be river crab natural feed is provided, and silt depth generally is no more than 5 centimetres at the bottom of the pond.Should build around the crab pond and prevent escaping facility, as brick wall, plastic film etc.The intake-outlet in crab pond is used wire netting and is blocked, in case the river crab flight.
In the prior art, the pond of propagating crab artificially is too high to the requirement of natural environment, is not easy to find suitable plant.According to the life habit of crab, crab likes enclosing in the pond edge, the ridge, and crab is bellicose, flood competition is strong, and the density that can culture crab in the common pond is less.
Summary of the invention:
The object of the present invention is to provide a kind of high density crab cultivation to use the pond, can culture the little problem of crab density to solve in the existing pond.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of high density crab cultivation is used the pond, it is characterized in that: be provided with the multiple tracks low bank of earth between fields in the described pond, and by the low bank of earth between fields waters in the pond is separated into continuous circulation water channel, the oxygen-increasing device of water-bed inflation is set in the described circulation water channel, and the power of water circulation is provided by oxygen-increasing device.
The described low bank of earth between fields is provided with mild low bank of earth between fields inclined-plane, and low bank of earth between fields inclined-plane in easy flights in 1/3 can prevent that crab from burrowing.
Plant on the described low bank of earth between fields inclined-plane and be implanted with pasture and water, pasture and water are convenient to water body and circulate along the parallel plantation of water (flow) direction, flowing water environment crab growth preferably.
Described oxygen-increasing device one side is provided with baffle plate, baffle plate bottom water flowing, and oxygen-increasing device is inflated from water bottom, and in the bubble floating process, a side is stopped that by baffle plate it is mobile to opposite side to drive water body, thereby makes the water generates wake flow in the pond, crab growth preferably.
Described oxygen-increasing device arranges one or more according to pond size and water velocity, according to the different power of air pump and the size of pond area, selects with an oxygen-increasing device or a plurality of oxygen-increasing device, thus water velocity and flow in the adjusting pond.
When throwing something and feeding bait, evenly throw along the water channel in the pond by the rail mounted automatic charging device and to spill bait, prevent that crab from fighting for food mutually.
The invention has the beneficial effects as follows:
Compare with existing crab cultivation pool, the present invention increases the suitable area of culturing crab in the pond by the low bank of earth between fields is set in the pond, increased the density that can culture crab in the pond greatly, compares with traditional crab pond, and cultivation density can improve more than three times; The low bank of earth between fields is separated into continuous water channel with the waters in the pond, and water body is flowed, and is conducive to improve the dissolved oxygen amount of water body, adapts to the life habit of crab; The low bank of earth between fields gradient is little, can prevent that crab from burrowing, and oxygen-increasing device can improve the water body dissolved oxygen rate from water-bed oxygenation, drives water body simultaneously and flows.And keep the low bank of earth between fields when in the pond, excavating, be convenient to when the pond reduction is ploughed flat again.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is schematic cross-section of the present invention;
Fig. 3 is the structural representation of baffle plate and oxygen-increasing device.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiments and the drawings, further set forth the present invention.
As Figure 1-3, a kind of high density crab cultivation is used the pond, be provided with the multiple tracks low bank of earth between fields 4 in the pond 3, and by the low bank of earth between fields 4 waters in the pond 3 are separated into continuous circulation water channel 5, the oxygen-increasing device 2 of water-bed inflation is set in the circulation water channel 5, and provided the power of water circulation by oxygen-increasing device 2, the low bank of earth between fields 4 is provided with mild low bank of earth between fields inclined-plane, low bank of earth between fields inclined-plane in easy flights in 1/3, can prevent that crab from burrowing, plant on the low bank of earth between fields inclined-plane and be implanted with pasture and water that pasture and water are along the parallel plantation of water (flow) direction, be convenient to water body and circulate, flowing water environment crab growth preferably.
Oxygen-increasing device 2 one sides are provided with baffle plate 1, baffle plate 1 bottom water flowing, oxygen-increasing device 2 is inflated from water bottom, in the bubble floating process, one side is stopped by baffle plate 1, will drive water body flows to opposite side, thereby make the water generates wake flow in the pond, crab growth preferably, oxygen-increasing device 2 arranges one or more according to pond size and water velocity, according to the different power of air pump and the size of pond area, select with an oxygen-increasing device or a plurality of oxygen-increasing device, thus water velocity and flow in the adjusting pond.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and the specification only is preference of the present invention; be not used for limiting the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
