Description

A kind of prawn industrial cultivation pond microalgae levitation device
Technical field
The invention belongs to aquaculture fields, more particularly to a kind of prawn industrial cultivation pond microalgae levitation device.
Background technique
Prawn industrial cultivation is mainly characterized by cultivation density height, and daily ration, feeding quantity is big.High cultivation density and a large amount of bait throwing in gesture Increasing for residual bait and excrement in breeding water body must be caused, is risen so as to cause inorganic nitrogens indexes such as ammonia nitrogens in water body.It swims micro- Algae can effectively absorb the inorganic nitrogen in breeding water body, have the function that improve water quality.Illumination is influenced in prawn culturing water body The main ecological factor of micro algae growth, however, a large amount of residual bait and excrement, which often lead to water transparency, to be reduced and make bottom Microalgae lacks illumination.During prawn culturing, high density microalgae is easily precipitated, and due to illumination deficiency, is in bottom frustule Hardly result in illumination.It maintains the basic light application time of frustule growth not to be able to satisfy, often leads to the death of microalgae, it is difficult to construct Stable excellent algae phase.
Summary of the invention
The technical problem to be solved in the present invention is that providing a kind of prawn industrial cultivation pond microalgae levitation device, the present apparatus By the way that micro-pore oxygenation pipe is arranged at aquaculture pond bottom, gas stone, gas collecting tube and steering elbow are matched, and make culturing pool recycle stream Dynamic, algae is in suspended state, is conducive to algal grown, and the algae of breeding water is kept to balance each other.
The present invention is achieved by the following technical solutions:
A kind of prawn industrial cultivation pond microalgae levitation device, it include positioned at the micro-pore oxygenation pipe at aquaculture pond bottom, gas stone, Gas collecting tube turns to elbow, fixed frame, tracheae and air blower, and bottom of pond micro-pore oxygenation pipe parallel laid is in aquaculture pond bottom, aquaculture pond bottom Periphery is equipped with the 2-4 gas stones for being fixed on aquaculture pond bottom, and 2-4 centimeters are provided with a collection perpendicular to aquaculture pond bottom right above gas stone Tracheae, gas collection pipe diameter are greater than gas stone diameter, and gas collecting tube is fixed on pool wall by fixed frame, turn to elbow one end and connect gas collection tube top End opening, the other end is parallel and lower than 2-4cm below water surface for aquaculture, and port open, steering elbow is consistent with water inlet pipe direction, gas Stone and micro-pore oxygenation pipe are connected by tracheae with air blower.
In use state, enter micro-pore oxygenation pipe by air one of tracheae entrance, by micro-pore oxygenation pipe Venthole flows water flow from bottom to top, and the gas in tracheae another enters gas stone, and the gas come out from gas stone impacts water flow Upwards, just enter gas collecting tube, after reaching gas collecting tube upper end, the water flow in gas collecting tube be diverted elbow change direction, with into The water (flow) direction for entering aquaculture pond is consistent, drives the water in aquaculture pond to rotate horizontally, therefore, the breeding water of entire aquaculture pond is micro- Hole oxygen increasing tube, gas stone, gas collecting tube and turn to elbow cooperation under, up and down, horizontal cyclic rotation, to make the algae phase in aquaculture pond In suspended state, algae Xiang Wending is maintained.
Detailed description of the invention
Fig. 1 aquaculture pond and microalgae levitation device sectional view of the present invention: 1, aquaculture pond, 2, micro-pore oxygenation pipe, 3, gas stone, 4, collection Tracheae, 5, steering elbow, 6, fixed frame, 7, tracheae, 8, air blower.
Specific embodiment
Explanation is further described to technology of the invention below by specific embodiment.
Unless otherwise specified, raw material employed in the embodiment of the present invention are the common raw material in this field, are implemented Method employed in example, is the conventional method of this field.
A kind of prawn industrial cultivation pond microalgae levitation device, as shown in Figure 1, it includes micro-pore oxygenation pipe 2, gas stone 3, collection Tracheae 4 turns to elbow 5, fixed frame 6, tracheae 7 and air blower 8, and micro-pore oxygenation pipe parallel laid is in 1 bottom of aquaculture pond, aquaculture pond bottom Periphery is equipped with 3 gas stones for being fixed on aquaculture pond bottom, and the vertical aquaculture pond bottom of 2 centimeters is provided with a gas collecting tube right above gas stone, Gas collection pipe diameter is greater than gas stone diameter, and gas collecting tube is fixed on pool wall by fixed frame 6, and gas collecting tube top is connected with elbow 5 is turned to, and turns Gas collecting tube top end opening is connected to elbow one end, the other end is parallel and is lower than water surface 2cm, belongs to open type, turns to elbow and water inlet Pipe direction is consistent, and gas stone and micro-pore oxygenation pipe are connected by tracheae 7 with air blower 8.
The construction method of brackish water prawn industrial cultivation pond green alga algae phase is carried out using described device, the green alga is Platymonas helgolandica var, the specific steps are the algaes of preparation stage mutually to construct, cultivates algae early period, which mutually maintains, cultivates middle and later periods algae mutually maintains;
The algae of the preparation stage mutually constructs, including intakes in aquaculture pond, after being sufficiently aerated without chlorine residue, will train through expanding Platymonas helgolandica var algae solution after supporting slowly uniformly is poured into aquaculture pond and is inoculated with, and initial inoculation concentration is (1-3) × 104cell/ Ml, after inoculation, it is ensured that green alga is in suspended state, observes water body color daily, counts under optical microscopy and observes green alga life Long situation, after 3-5 days, chlorella cell number reaches (0.8-1.0) × 10 in water body5Cell/ml can launch shrimp seedling.
Early period is cultivated, does not change water, blowdown after bait throwing in 1-2h, blowdown flow rate is about the 3-5% of total breeding water body, is filled after blowdown New water, water is through 230 mesh net filtrations;
The cultivation middle and later periods algae mutually maintains, and cultivates the middle and later periods, observes water body color daily, counts under optical microscopy And observe Platymonas helgolandica var growing state.According to count results under microscope, adds Platymonas helgolandica var culture solution or pass through row Water discharge part Platymonas helgolandica var, makes micro algae density maintain (0.8-1.0) × 105cell/ml.It supplements within every 10-15 days Apply an one-lime phosphate, dosage 3-5g/m3;Every 15-20 days, apply an ironic citrate, dosage 0.2-0.5g/m3.It supports Grow the middle and later periods, every 10-15 days, spilled once it is activated after bacillus subtilis.With the increase of prawn daily ration, feeding quantity, arrange daily Dirt amount is the 5-10% of total breeding water body;
Embodiment 1
Experiment carries out (amounting to 84 the experimental period 5-8 month in 2015 at Jiangzhou brackish water prawn industrial cultivation test site It).Litopenaeus vannamei breeding density is 300 tails/m3.Experimental water mud sump is round (radius=0.97m, height=1.0m), Totally 36, wherein 30 inoculation Platymonas helgolandica vars, operate according to the above method;6 are tradition " shining water " cultural method, are not inoculated with micro- Algae, daily quantity of exchanged water are 10-30%.During experiment, salinity (20.78 ± 0.06) ‰, temperature (29.87 ± 0.13) DEG C.
The result shows that algae Xiang Wending during inoculation Platymonas helgolandica var group cultivation, and traditional cultivation group cultivation later period appearance is micro- Capsule algae and silkweed.Being inoculated with Total inorganic nitrogrn in Platymonas helgolandica var group water body reduces by 89.4% He than traditional cultivation group respectively 90.5%;Prawn opisthosoma is respectively (18.04 ± 1.36) g and (14.30 ± 0.08) g again;Prawn yield difference (4.41 ± 0.14)kg/m3(2.41 ± 0.04) kg/m3
Apparatus of the present invention can be equally used for other beneficial algae cultures and cultivate to aquatic livestock.
