Abstract
The invention relates to a method for cultivating amphiprora alata used for regulating water quality in higher-place pond prawn cultivation, and belongs to the technical field of aquaculture. According to the features of a long growth period and stable cultivation water quality of the amphiprora alata, before shrimps are put into a higher-place pond, the amphiprora alata is cultivated directionally in the higher-place pond, the method includes the specific steps that the amphiprora alata is cultivated in a laboratory firstly, then is cultivated in an outdoor cement pond and is inoculated into the higher-place pond to be cultivated finally; after being cultivated in the higher-place pond for 7 days to 8 days, the amphiprora alata becomes dominant species, and the shrimps can be put into the higher-place pond. The method is simple and convenient to operate, the technology is easy to master, the mode that the cultivation water ecological balance is sustained through large-scale discharge and large-scale irrigation in traditional higher-place pond prawn cultivation is avoided, the cultivation pond water is tawny, the transparency is moderate, the ecological system can be kept in a stable state for a long time, the usage amount of chemicals and diseases are reduced obviously, the rate of successful cultivation is increased, the cultivation cost is reduced, the economical benefit is remarkable, and the body colors of obtained prawns are good.
Description
Technical field
The present invention relates in a kind of prawn high-elevation breeding pond to cultivate there is eurysalinity, method that the stable and adaptable micro-algae of population regulates breeding environment, a kind of method that is specifically related to cultivate in prawn high-elevation breeding pond wing cocoon shape algae regulating water quality, belongs to technical field of aquaculture.
Background technology
Prawn intensive culture is under manual control condition, to use the various up-to-date technological meanses such as modern project, chemistry, biology, electromechanics, automation and use environment-protecting feed, carries out a kind of aquaculture model of prawn high-density breeding.In recent years, in prawn culturing process in order to pursue high yield, in improving cultivation density, drop into a large amount of artificial feed, cause a large amount of residual baits, prawn ight soil and dead organism chip etc. to accumulate in shrimp pond, make dissolved nitrogen become nitrogen-containing pollutant matter important in prawn culturing ecosystem water body, these nitrogen-containing pollutant matter cause the eutrophication of water body and cause the deterioration of cultivate water, make the survival rate of prawn morbidity and impact cultivation.Research shows, the nitrogen of putting in pond culturing system only has 20% ~ 30% to be converted to protein, the remaining overwhelming majority is all discharged in extraneous water environment or deposits in the substrate in pond, in fishing breeding pond, deposits every year the mud of 10 cm ~ 12 cm.NH
4 +-N and NO
2 --N is poisonous nitrogen-containing pollutant important in intensive shrimp ecosystem, NO
2 -the poisonous nitrogen-containing pollutant matter such as-N has become stress factors important in shrimp ecosystem.NH in water body
4 +when-N excessive concentration, can reduce significantly immunocompetence and the resistance against diseases of prawn." support shrimp and first support water ", the quality of condition of water quality directly affects process of growth and the resistance against diseases of prawn culturing, and the water quality environment of prawn pool carries out the regulation and control of science, can improve significantly the output of prawn culturing success rate and cultivation.
Micro-algae is living aquatic resources very important in ocean, and its reproduction speed is fast, and contains a large amount of terrestrial lifes shortages and unique bioactivator.Some planktonic microalgae are as wing cocoon shape algae also has orientable cultivation in breeding water body, the feature such as strong and structure of community easy-regulating to adaptive capacity to environment.Because micro algae growth need to be from water environment the nutriment such as absorbed nitrogen, be the important channel that in aquatic ecosystem, dissolved nitrogen transforms.Simultaneously microalgae cell can be absorbed and be removed nitrogen-containing pollutant matter poisonous in water body, has the dissolved oxygen that improves in water body and the function of pH by photosynthesis, so utilize micro-algae to purify environment of prawn ponds water quality, be a kind of water technology favourable and with low cost to environmental health.Wing cocoon shape algae (Amphiprora alata) belongs to plumage line Bacillariophyceae (Pennnatae), has shell seam diatom order (Raphidinales), Naviculaceae (Naviculaceae k ü tzing), cocoon shape Trentepohlia [Amphiprora (Ehrenberg) cleve], be a kind of diatom of brown, there is eurysalinity, the stable and adaptable Biological characteristics of population in shrimp pool water body.Therefore in the shrimp pool, large-scale culture wing cocoon shape algae can be stablized breeding environment water quality, reaches the object of prawn ecologic breeding.
From the shrimp pool, isolate purebred wing cocoon shape algae, after three grades of cultivations such as domestication and purebred cultivation, the cultivation of indoor conical flask and outdoor tank-culture cultivation, move on to high-order pond from cement pit again and cultivate, treat that wing cocoon shape algae propagation is to certain density, then throw in shrimp seedling.Cultured prawn is in this way adopted in high-order pond, breeding process water stabilization, and water colour is yellowish-brown, and transparency is suitable; Breeding process disease is few, thereby reduces dosage, has reduced aquaculture cost, increasing both production and income.The method yet there are no report at present.
Summary of the invention
The object of the invention is to provide a kind of method of cultivating wing cocoon shape algae regulating water quality in prawn high-elevation breeding pond, the method technology is easy to grasp, easy and simple to handle, can keep for a long time the breeding water body ecosystem stable, can reduce disease occurs, improve prawn output and reduce aquaculture cost, remarkable in economical benefits.
For addressing the above problem, the technical solution adopted in the present invention is:
A method of cultivating wing cocoon shape algae regulating water quality in prawn high-elevation breeding pond, comprises the steps:
(1) wing cocoon shape algae cement pit is cultivated: the cement pit area 20m that cultivates wing cocoon shape algae
2, the dark 1.2m in pond; After cement pit washes, add filtered seawater 0.8～1.0m, then carry out pond water sterilization with strong chlorine oil, after 24h hour, use again sodium thiosulfate neutralisation treatment constantly sudden and violent gas 7～8 hours; Treat that in water, chlorine residue all disappears, add the nutriment such as nutritive salt and assisting growth organic matter, then the wing cocoon shape algae in indoor cultivation is inoculated into cement pit;
(2) cultivate in the high-order pond of wing cocoon shape algae: high-order pool area 2000～3400m
2, the dark 1.8～2.0m in pond, lays respectively at Si Ge angle, pond the waterwheel aerator that a power is 0.75kv; The wing cocoon shape algae for the treatment of cement pit grows into certain density, thorough high-order pond cleaning and sterilizing, add the seawater 1.2m through sedimentation and filtration, then discharge inorganic nutrient salt, start aerator Chi Shui is fully mixed, finally the wing cocoon shape algae of cultivating at cement pit is moved on to high-order pond and cultivate, cultivate 7～8 days, wing cocoon shape algae becomes dominant population in high-order pond, just can throw in shrimp seedling;
(3) management: cement pit is cultivated the uninterrupted qi of chong channel ascending adversely in 24 hours of wing cocoon shape algae, prevents that frond from sinking, and while cultivation in high-order pond, 8 o'clock every mornings and at 17 o'clock in afternoon are started respectively aerator 2 hours; After throwing in shrimp seedling, appended inorganic fertilizer every 15 days, to keep the density of water body wing centre section cocoon shape algae.
The described pond water sterilization strong chlorine oil usage amount of step (1) is 10g/m
3, in and water in chlorine residue sodium thiosulfate used be 4g/m
