Description

A kind of giant salamander simulated primitive ecology propagation method
Technical field
This invention relates to giant salamander simulated primitive ecology propagation method field.
Technical background
Is what problem giant salamander (having another name called the giant salamander) giant salamander artificial propagation techniques also in experimental stage so far, and the giant salamander artificial reproduction rate is low, is actually? we are summarized as following several problem:
(1). female, male gland is grown asynchronous, and it is because being water temperature and bait, because water temperature and bait are the decisive factors of On The Gonadal Development of Megalobatrachus Davidianus.
(2). dead ovum can not be fertilized, be commonly called as to female a large amount of ovum of giving birth to, and this explanation ovum does not also reach physiology and the modal maturation that fertilization is learned.The ovum that female salamander gives birth to is no less than ten thousand of 5-30 every year, and in fact, the giant salamander seed that each company breeds out every year only has about the 8000-30000 tail, and dead ovum rate is up to 90-95%.The reason of dead ovum: the one, the factor of protein own causes, and the 2nd, unfertilized causing.Dead ovum is the ubiquitous problem in each base, and this is undisputable fact.
(3). female difficult labour phenomenon ubiquity.Less of giant salamander natural labor accounts for 10-20%, and all the other are difficult labour; Card neck when namely laying eggs.
(4). male semen quality is poor.As everyone knows, the male sperm major part of extruding is dead essence, and secondly sperm viability is low.The poor reason of semen quality is that giant salamander lacks production of sperm protein.Sperm death is production of sperm mechanism depauperation and seminal fluid fructose, V A , V E And the material such as spermidine low due to.Say that with theory of traditional Chinese medical science semen quality is poor, then be the loss of deficiency of kidney-QI, kidney yang, change and give birth to not as good as and to cause vital essence on the decline, the body liver is lost bar and reaches, and qi and blood freely is not the basic reason that causes Necrospermia; This and giant salamander long term survival have very big correlation in the water environment of low temperature half-light, and it is the factor that causes deficiency of kidney-QI, kidney yang to lose that giant salamander survives in sombre water environment with half-light, thereby cause giant salamander Necrospermia and vigor low.There is the researcher to improve the giant salamander sperm quality with the fish sperm nutrient solution, its effect is very little, hardly realizes, because giant salamander lacks production of sperm albumen, that is to say the sperm inadequate natural endowment, you well imagine with the sperm quality poor effect that the fish sperm nutrient solution improves giant salamander.It is exactly the unsuitable required special phytoplankton of On The Gonadal Development of Megalobatrachus Davidianus in the pond that the problems referred to above are summed up; Namely there is not enough amino acid, the giant salamander congenital malformation, therefore, male sperm vigor of poor quality is low.
(5). the easy mortality of development of fertilized ova later stage embryo.The fertilized egg Late Embryogenesis refers to tail bud phase to demoulding this one-phase of emerging.Its cause of death is that ovum collagenic protein wretched insufficiency causes due to the water mold.
(6). young salamander deformity quantity is large.Young salamander deformity ratio generally has 30%, and its reason is in close salamander calcium deficiency and the water due to the heavy metal pollution.
(7). manually be difficult to select sexual maturity parent salamander.
Existing simulated primitive ecology propagation method (CN101081008) Shortcomings mainly is because do not have Illumination adjusting in the pond, does not have to cultivate and safeguard the method for boat-shaped algae, avette algae in the pond, and current lack certain flow velocity.And cultivate and safeguard that the algae such as boat-shaped algae, avette algae are the crux places of simulated primitive ecology breeding success or failure, also be the key point that can the simulated primitive ecology breeding hold breeding.

Throw in photosynthetic bacteria and probio in the pond, photosynthetic bacteria and probio weight ratio are 2:1.Safeguard algae and improve water quality.Its bacterium amount is 2~30mg/ L.
Algae composition in the simulated primitive ecology breeding pond:
A. the species composition of algae in the pond: in taxon, contain the algae of 5 Algaes, 8 guiding principles, 19 orders, 33 sections, the species number of Bacillariophyta is maximum, reaches 19 and belongs to 61 taxons, accounts for 80%; The species number of Chlorophyta takes second place, and is 5 taxons of 4 genus, accounts for 6%; Being Cyanophyta again, is 4 taxons of 3 genus, accounts for 5%.Other each algal kind number is less, only has 6 to belong to 6 taxons.The overwhelming majority is the kind of pennates in the diatom, account for 96. 55% of diatom species number, wherein especially with the Naviculaceae NavicuLaceae of bivalve seam order BiraPHinaLes and the Fragilariaceae ragiLariaceae most species of Araphidinales AraPHidiaLes, reach respectively 17 and 16 taxons.(kind of Centricae is few, only finds rotary strainer algae section (oscinodiscaceae) Melosira for the center guiding principle M eLosira2 taxons.
Algae dominant population in the simulated primitive ecology breeding pond: from the angle analysis of algae door, the ratio maximum that Bacillariophyta is shared, reaching 80%, is Chlorophyta secondly, accounts for 6%, diatom and Chlorophyta differ greatly, be Cyanophyta again, account for 5%, other each the kind ratio of counting adds up to and all is no more than 9%, this shows, diatom is dominant population.In the guiding principle one-level, diatom is maximum; In the order one-level, diatom tops the list; In section's one-level, diatom also is that the Navicula of Bacillariophyta is maximum in belonging to one-level.As seen, in each taxonomical hierarchy, diatom all is dominant population.
The species diversity of algae in the simulated primitive ecology breeding pond: the index of species diversity of Bacillariophyta is the highest H/=5.18, be Chlorophyta secondly H/=0.38, be Cyanophyta again H/=0.32, the diversity indices of all the other algae doors is lower.The Bacillariophyta algae species is the abundantest, amount to 19 and belong to 61 taxons, the green alga species number at most but diversity indices not as good as diatom, amount to 4 and belong to 5 taxons, the blue-green algae diversity indices is low, other each all only find several genus, species are more single.
The main group of algae in the simulated primitive ecology breeding pond: (1). Navicula is preponderated in the diatom group, and sociales are short and small boat-shaped algae N avicuLa. exigua, pupil boat-shaped algae N avicu2 La. pupuLa,Secondly be a small amount of kind of Melosira, gomphonema, Fragilaria, Diatoma, Nitzschia etc.This group belongs to planktonic algae community ,And be the advantage group in the streams.(2). water silk floss-sheath silk algae group is by Spirogyra SpirogyraLight water continuous S pirogy ra. comm unisWith the sheath Ulothrix LyngbyaLarge-scale sheath silk algae Lyngbya. m a iorPeriphyton community for sociales ,With it mixed give birth to the multiple diatoms such as Melosira, Navicula, Cymbella are arranged ,Some kinds that also have in addition the Cyanophyta microcystis kutz.This group often is distributed in organic more rich waters.(3). the periphyton community of dwelling at the bottom of the curved algae alliance of bridge has Cymbella Cym beLLaThe curved algae of nearly edge bridge Cym beLLa. aff inis, the partially swollen curved algae of bridge Cym2 BeLLa. ventricosa,All the other diatoms have short and small boat-shaped algae N avicu La. ex igua, blunt crisp bar algae FragiLa ria. capucina, the sheet algae such as common D. vu La2 GareWith little shank algae etc.Mainly be distributed in the milder shallow water bottom of current, be attached on deadwood, slabstone, the foreign material.(4). the sociales of nostoc group are Nostoc Commune N ostoc. comm uneWith spherical nostoc N ostoc. sPHaericum,Therebetween also must algae with Rao Shi glue R ivuLaria. jaoi, the peace and quiet algae that quivers OsciLLatoria. sanctaReach the diatom kinds such as a small amount of Navicula, Cymbella.This group often is distributed in shallow water area.
E. simulated primitive ecology is bred the temporal-spatial distribution characteristic of algae in water body in the pond: the living environment of algae is heterogeneous, from the time, the factor that significantly changes such as temperature, intensity of illumination, hydrodynamics characteristic, nutrients utilizability etc., these changes can be reflected at different time horizons.Because the intensity of illumination that the different depth water layer is accepted and the significant difference of water body thermodynamic state, the heterogeneity that little algae is distributed in spatial vertical also is obvious.And all above these factors have facilitated little algae to have successional vertical distribution phenomenon.Itself also can strengthen vertical demixing little algae, and for example, little algae descends in bottom and decomposition after the top layer absorbs nutrition, then can cause the shortage of top layer nutrition and the increase of deep layer nutrition; The microactuator suspension frond is to absorption and the scattering of sunlight, makes intensity of illumination more remarkable with the phenomenon that the increase of the degree of depth weakens.In addition, envirment factor also affects the distribution of little algae, such as wind direction, current, water level etc.
The seasonal succession rule of algae in the simulated primitive ecology breeding pond: the seasonal variation that the diatom population forms can be caused by the compound action of two kinds of mechanism or two kinds of mechanism.Two kinds of mechanism refer to that succession and order change.Succession is that the kind that the change of physics (such as light, temperature), chemistry (nutrients, water quality, toxin) and biological (compete, ingest) factor in the specific body of water causes changes, and order then is that the kind that is caused by the change of water body type changes.A typical succession is the variation of intrinsic kind, and typical order variation then is the allochthonous population introducing and breeds caused.Diatom seasonal succession also is subjected to some other factor affecting.For example, the decline of diatom biomass is probably low relevant with the regeneration rate of water body mixing layer silicon.And in the water body layering period of nutritional deficiency, swarm cell then may utilize its ability of moving about initiatively to look for suitable position and preponderate.From metaboilic level, the sloping portion of summer plankton amount can be thought due to the decline of photosynthesis and respiration rates.Because the nutrients shortage has reduced photosynthesis rate, and high temperature has improved respiratory rate, thereby causes low clean biomass.Giant salamander original producton location small stream korneforos wet season and dry season algal kind change.

2). Ecology breeding hole, cave structure: the hole, cave is the giant salamander home. the hole, cave is curved, the hole can freely ingest giant salamander to the pond in the pond, the high 20~30cm that is of the length and width of Chi Kou, long 0.8~1.2 meter of hole, cave, wide 0.8~1 meter, high 0.3~0.4 meter, the hole, cave is low early and high after, hole, cave interior wall is built into cobble stone, boulder, bottom, hole, cave spreads 5~10cm bed course with gravel pebbles, and hole, the cave top clay plate of water or local slabstone cover earthing 50~80cm heat-insulation warm keeping; The plantation pasture and water are shaded on earthing, and permeability cell is installed in top, hole, cave, and a water inlet pipe is installed in the hole, cave, and mouth of pipe clockwise direction is so that hole, cave water flow.
3) close salamander is cultivated:
Close salamander (male, female input ratio is 1:2) is dropped in the Ecology breeding pond, according to the On The Gonadal Development of Megalobatrachus Davidianus rule, adopted natural temperature differential flowing water to raise close salamander, throw something and feed fresh and alive mountain stream small fish and river prawn.Summer high light, adopt the shading screen regulating illumination, illumination is controlled at 1500~3000Lx, in order to algal grown in the water and breeding.In annual 4-10 month, 4 days with probiotics (photosynthetic bacteria and probio) once, and probiotics is watered in Xiang Chizhong and the hole, cave splashes, and decomposes residual bait and purify water.Inlet channel will be opened once every day in the hole, cave, makes to form flowing water in the hole, cave each half an hour, stimulates On The Gonadal Development of Megalobatrachus Davidianus.In time close the flood retention lock between flood period, can not allow flood pollute and cultivate the pond.10 meters on barrier is established a puddle between needing in the ecological pool, slows down flow velocity, allows the giant salamander more little algae that ingests supply with gonad development.
Concrete breeding condition comprises:
A. water source:
The water source must be streams, original producton location water, and water do not have contaminatedly, and phytoplankton and physical and chemical factor in the water source meet the requirements again.Water source and the water yield should manage to make its cleaning with stable; In the pond and the bank plant look its growth and competitive situations and do at any time gradation and put in order in batches, keep the pond biological chain of diversity.Should be removed at any time for denizen and invasion property species.The vegetal cover degree of pond face is the most suitable between remaining on 20 ~ 40%, and the food source of organism in water abundance can be provided on the one hand, and that can keep on the one hand higher green landscape and giant salamander perches, keeps away the enemy place.
Water quality: more than dissolved oxygen 5~6mg/L, mineralization degree is high, and hardness is large, pH6.4~7.2.Calcium content 38.3~52.6mg/L, the content 13.2~18.6mg/L of magnesium, water quality is pure and fresh;
C. water temperature: water temperature is the key factor of giant salamander breeding, and wherein the optimum growh developmental temperature is 19~22 ℃, and 8~25 ℃ is the suitable scope of giving birth to, and is lower than 10 ℃ or be higher than 25 ℃, and giant salamander ingests and significantly reduces, and growth obviously slows down.Water temperature in winter is 4~12 ℃, and low temperature is grown the giant salamander performance the promotion effect, and water temperature in winter is unsuitable too high, and too high water temperature can affect the giant salamander performance and grow;
D. the depth of water: water depth is 0.4~1.97 meter, 0.2~0.3 meter of hole, the cave depth of water.Water flow velocity 0.22~0.5m 3 / min, discharge is not excessive, and flow velocity is crossed conference affects biological chain normality derivation in the pond.;
E. water flow velocity: water flow velocity 0.22~0.5m 3 / min;
F. illumination: the inside illumination of hole, cave at 1500 ~ 2500Lx, must hide with shading screen when illumination surpasses 3000Lx in the pond in the pond at 300 ~ 1000Lx.It can affect the derivation of organism in water chain when illumination surpassed 3000Lx in the pond, if the abnormal derivation of biological chain in the pond, giant salamander can't absorb the required protein of gonadal maturation, so giant salamander is difficult to the naturality maturation, also just can't the natural birth salamander.
Support algae in the water: it is algae in the water that the giant salamander breeding relies on, and ecotope is external cause, and internal cause then is nutrition, and namely the ripe required algae of suitable On The Gonadal Development of Megalobatrachus Davidianus namely mainly is the algae such as boat-shaped algae, avette algae.In the situation that the external cause condition is identical, the algae such as the nutritive element boat-shaped algae of internal cause, avette algae have determined the reproduction rate of giant salamander.Certainly the dynamic equilibrium between algae door, kind and the biocoenosis is very important.This also meets the rule of fish reproduction physiology genesiology.The fish reproduction physiological knowledge is told the quality that our fish nutrition is determining the fish gonadal maturation, that is to say that giant salamander nutrient has determined reproduction rate of giant salamanders.
Result of the test:
The high literature in Ningqiang County, Hanzhong, the field is built in Zhou Zhijun Ecology breeding in Mian County then, puts then kind of a fish in a suitable place to breed, when producing seedling per year; Particularly the high literature in Ningqiang is built the pond completion in August, 2007, and August 7, he just put kind of a fish into, and September 23 was laid eggs more than 1000, and December 15 began to emerge, and emerged on January 10th, 2008 complete, and the natural spawning fertilization brooding time reaches 108 days, produces seedling 800 tails; Water temperature be 5 to 10 the degree ℃.And artificial propagation, the spawning and fertilization brooding time only has 45 days, and water temperature is 18 to 24 ℃, and saprolegniasis easily occurs when the artificial incubation water temperature is lower than below 16 ℃; And saprolegniasis does not occur in water temperature yet in the time of 5 to 10 ℃ during the hatching of Ecology breeding nature; This is because in the ovum enough natural antibodies are arranged.
The giant salamander Eco Environmental Factors mainly is height above sea level, vegetation, water quality, water temperature, PH, dissolved oxygen, the depth of water, flow, illumination, bait, hole, cave etc., these Eco Environmental Factors just help out to the giant salamander breeding, and the decisive action factor is nutrition and property functional system.
Giant salamander breeding ecology environment is external cause, internal cause then is nutrition, algae under the On The Gonadal Development of Megalobatrachus Davidianus maturation that namely suits, algae is completeness albumen, namely be nutrition, in the situation that the external cause condition is identical, the nutritive element of internal cause plays decisive role, and this also meets the rule of fish reproduction physiology genesiology.Fish reproduction physiology and knowledge are told the quality that our fish nutrition is determining the fish gonadal maturation, that is to say that fish nutrition has determined the fish reproduction rate.The On The Gonadal Development of Megalobatrachus Davidianus maturation needs a large number of nutrients, livetin chemically be not single albumen, its main component be lipovitellin (lipoprotein) it be the main body that consists of giant salamander yolk, needs for embryonic development, as seen, the giant salamander parent needs in the gonad development process from external world's absorption a large number of nutrients.Particularly lay in sufficient albumen and fat.It is the precursor that giant salamander is converted into lipovitellin, also is smart source protein institute energy requirement.The ecological algae in small stream korneforos that originates in giant salamander is rich in the On The Gonadal Development of Megalobatrachus Davidianus desirable proteins.
Test shows: tell us, the breeding of giant salamander simulated primitive ecology is produced young salamander amount at the 300-1500 tail.The breeding of Jian Da Salamander Ecology is laid eggs and the breeding of information slip and simulated primitive ecology and the artificial propagation situation comparison sheet of emerging.
