Abstract
The invention relates to the technical field of aquaculture, in particular to a high-density breeding method used for a green crab breeding pond. Green crabs are bred in the pond. The method is characterized in that a plurality of earth ridges are arranged in the pond and used for dividing a water area in the pond into continuous circulating water channels; water in the pond directionally and circularly flows in the circulating water channels; oxygenation devices used for filling the bottom of the water with oxygen are arranged in the water channels of the pond and used for providing power for water circulation; the earth ridges are provided with gentle earth ridge inclined surfaces; the slope of each earth ridge inclined surface is not greater than 1/3; aquatic weeds are planted on the earth ridge inclined surfaces. The earth ridges are arranged in the pond, so that the suitable crab breeding area in the pond is enlarged, the crab breeding density in the pond is greatly increased, and the breeding density can be increased by more than three times in comparison with that of a conventional crab pond; the earth ridges are used for dividing the water area in the pond into the continuous water channels, a water body flows, the dissolved oxygen amount is high, and the slope of each earth ridge is small, so that the crabs can be prevented from making holes.
Description
Technical field
The present invention relates to technical field of aquaculture, especially a kind of high-density breeding method for blue crab cultivation pond.
Background technology
Propagate crab artificially very high to the requirement of plant, at present the pond of cultivation crab, quadrature and generally be advisable at 1-5 mu, crab pond condition is had abundant water resources, and water quality is good, and Inlet and outlet water is convenient, and the depth of water generally with 1-1.5 meters as well.Crab pond substrate amount is preferably sandy loam, gravel soil, and venting capability is good, and be conducive to pasture and water, vegeto-animal growth and breeding is dwelt at the end, can be river crab and provides natural feed, silt depth at the bottom of pond is generally no more than 5 centimetres.The surrounding in crab pond should be built and be prevented escaping facility, as brick wall, plastic film etc.The intake-outlet application wire netting in crab pond blocks, in case river crab flight.
In prior art, the pond propagating crab artificially is too high to the requirement of natural environment, is not easy to find applicable plant.According to the life habit of crab, crab is liked at Wei Geng edge, pond, and crab is bellicose, flood competition strong, and the density that can cultivate crab in ordinary pond is less.
Summary of the invention
The object of the invention is to provide a kind of high-density breeding method for blue crab cultivation pond to overcome above-mentioned technical disadvantages.
The technical scheme that technical solution problem of the present invention adopts is: a kind of high-density breeding method for blue crab cultivation pond, be included in pond and cultivate, the multiple tracks low bank of earth between fields is provided with in described pond, and by the low bank of earth between fields, the waters in pond is separated into continuous print circulation water channel, water in described pond circulates at circulation water channel interior orientation, the oxygen-increasing device of water-bed inflation is set in the water channel in described pond, 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, low bank of earth between fields inclined-plane in easy flights in 1/3, low bank of earth between fields inclined-plane are planted and are implanted with pasture and water.
Throw something and feed feed time, evenly throw along the water channel in pond and spill feed, prevent crab from fighting for food each other.
Described pasture and water, along the parallel plantation of water (flow) direction, are convenient to water circulation flowing.
The oxygen-increasing device of described bottom inflation adopts oxygenation aeration pipe or nanometer aeration pipe to inflate from water bottom.
The oxygen-increasing device of described bottom inflation arranges one or more according to pond size and water velocity, the size of the power different according to air pump and pond area, select with an oxygen-increasing device or multiple oxygen-increasing device, thus regulate water velocity and flow in pond.
The beneficial effect that the present invention has is: the present invention by arranging the low bank of earth between fields and increasing in pond the optimum plot size cultivating crab in pond, and considerably increase the density that can cultivate crab in pond, compared with traditional crab pond, cultivation density can improve more than three times; Waters in pond is separated into continuous print water channel by the low bank of earth between fields, can make water body flow, is conducive to the dissolved oxygen amount improving water body, adapts to the life habit of crab; The low bank of earth between fields gradient is little, can prevent crab from burrowing, and oxygen-increasing device, from water-bed oxygenation, can improve water body dissolved oxygen rate, drive water body flow simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation in high-density breeding pond of the present invention.
Embodiment
Below in conjunction with accompanying drawing, 1 couple of the present invention is described below.
As shown in Figure 1, present invention resides in pond and cultivate, the multiple tracks low bank of earth between fields is provided with in pond, and by the low bank of earth between fields, the waters in pond being separated into continuous print circulation water channel, the water in pond circulates at circulation water channel interior orientation, arranges the oxygen-increasing device of water-bed inflation in the water channel in pond, and the power of water circulation is provided by oxygen-increasing device, the low bank of earth between fields 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, low bank of earth between fields inclined-plane is planted and is implanted with pasture and water; Being provided with above pond can the charging device of automatic charging, can ensure uniform feeding, improve the efficiency that feeds intake, reduce the workload of poultry feeders, be convenient to automatic management.
