Description

A kind of construction method of Underground Water in Salinization Area prawn industrial cultivation pond green alga algae phase
Technical field
The invention belongs to aquaculture fields, more particularly to a kind of Underground Water in Salinization Area prawn industrial cultivation pond green alga The construction method of algae phase.
Background technique
Acute Hepatopancreatic necrosis syndrome (the Acute Hepatopancreas of litopenaeus vannamei caused by vibrio parahaemolytious Necrosis Syndrome, AHPNS) diseases such as/Deaths syndrome (Early Mortality Syndrome, EMS) give Shrimp culture industry brings about great losses.As a kind of Halophiles, salinity is lower, and vibrio parahaemolytious growth and breeding speed is slower.Cause This, Underground Water in Salinization Area cultivation litopenaeus vannamei has higher success rate.Underground Water in Salinization Area due to pH and carbonate alkalinity compared with It is high and water quality is thin, planktonic organism negligible amounts, therefore experienced shrimp agriculture often first " shines water " in reservoir, recycles " green Water " supports shrimp.However, microalgae diversity is complicated in the water body through reservoir exposure, type is also unstable, is easily mixed into the nocuousness such as cyanobacteria Algae causes during prawn culturing microalgae sociales constantly to be become feeble and die and succession, it is difficult to which excellent algae phase is stablized in formation.Especially Harmful microalgae mass propagation such as microcystic aeruginosa, protokaryon unarmored dinoflagellate is often resulted in when cultivating the mistake eutrophication of middle and later periods water body, is made It is sick or dead at prawn.In addition, high density microalgae easily causes extinction to be obstructed and dead, generation due to precipitating in breeding process " algae " phenomenon, eventually leads to the failure of prawn culturing.
Constructing stable green alga algae mutually can be improved prawn culturing success rate.Platymonas helgolandica var all has salinity and temperature Extensive adaptability is green alga common in prawn culturing water body.Platymonas helgolandica var unsaturated fatty acid rich in, is pair Common bait micro-algae in shrimp seedling raising process.Some researches show that the secretion of flat algae and fat-soluble extractives etc. are to vibrios and vacation Monad has inhibiting effect.
Summary of the invention
The technical problem to be solved in the present invention is that providing a kind of Underground Water in Salinization Area prawn industrial cultivation pond green alga algae The construction method of phase.For this method by choosing eurysalinity, high temperature resistant, adaptable Platymonas helgolandica var, which constructs, stablizes algae phase, To optimize brackish water prawn industrial cultivation Water quality, promote prawn health fast-growth;
The present invention is achieved by the following technical solutions:
A kind of construction method of Underground Water in Salinization Area prawn industrial cultivation pond green alga algae phase, the green alga are that Qingdao is big Flat algae, the specific steps are the algaes of preparation stage mutually to construct, cultivates algae early period mutually maintains mutually to maintain with cultivation middle and later periods algae;
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 moves into aquaculture pond and is inoculated with, and initial inoculation concentration is (1-3) × 104cell/ml.Inoculation Afterwards, it is ensured that green alga is in suspended state, observes water body color daily, counts under optical microscopy and observe chlorella growth situation. After 3-5 days, chlorella cell number reaches (0.8-1.0) × 10 in water body5Cell/ml can launch shrimp seedling;
Cultivation algae early period mutually maintains, and cultivates and does not change water early period, blowdown after bait throwing in 1-2h, and daily blowdown flow rate is about total The 3-5% of breeding water body fills new water after blowdown;
The cultivation middle and later periods algae mutually maintains, cultivate the middle and later periods, make water body green alga density maintain (0.8-1.0) × 105Cell/ml, supplement applies an one-lime phosphate, dosage 3-5g/m within every 10-15 days3;Every 15-20 days, apply a lemon Sour iron, dosage 0.2-0.5g/m3;Every 10-15 days, spilled once it is activated after bacillus subtilis.The middle and later periods is cultivated, with The increase of prawn daily ration, feeding quantity, daily blowdown flow rate be total breeding water body 5-10%;
Further, the cultivation early period is before the long 3cm of shrimp seedling body;
Further, when being inoculated with Platymonas helgolandica var, Platymonas helgolandica var cell density (5-10) × 10 in inoculation liquid5cell/ mL;
Further, the aquaculture pond is equipped with microalgae levitation device, it includes micro-pore oxygenation pipe, the gas positioned at aquaculture pond bottom Stone, gas collecting tube and steering elbow, for bottom of pond micro-pore oxygenation pipe parallel laid in aquaculture pond bottom, aquaculture pond bottom perimeter is equipped with 2-4 admittedly 1-2 centimeters are provided with a gas collecting tube, gas collection pipe diameter perpendicular to aquaculture pond bottom right above the gas stone at aquaculture pond bottom, gas stone Greater than gas stone diameter, gas collecting tube is fixed on pool wall by fixed frame, turns to elbow one end and connects gas collecting tube top end opening, another to hold level with both hands It goes and is lower than water surface 1-3cm, belong to open type, steering elbow is consistent with water inlet pipe direction, and gas stone and micro-pore oxygenation pipe pass through tracheae It is connected with air blower.
The present invention compared with prior art the utility model has the advantages that
1) eurysalinity, high temperature resistant are chosen, adaptable Platymonas helgolandica var constructs algae phase, it is ensured that it is in brackish water aquaculture The adaptability in pond.
2) pass through building shrimp culture pond microalgae levitation device, it is ensured that in breeding process, Platymonas helgolandica var is in outstanding always Floating state, effectively prevent Platymonas helgolandica var that algae occurs down because of coagulation.
3) cultivate the middle and later periods, splash it is activated after bacillus subtilis, both facilitate ammonia nitrogen, the nocuousness such as nitrite nitrogen The removal of substance, and CO required for growth can be provided for Platymonas helgolandica var2
4) by control microalgae quantity, effectively building stablizes excellent algae phase, is conducive to the rapid life of regulating and controlling water quality and prawn It is long.
