Detailed description of the invention

The stone frog is the animal of a kind of integration of edible and medicinal herbs, cures mainly that children's's consumptive disease is thin at medical aspect, infantile malnutrition, weak after being ill, has benefit Deficient, relieving heat toxin, driving that consumptive disease is thin, effect of removing toxic substances skin ulcer, its ovum has the function of improving eyesight, and modern study also finds to contain in the skin and flesh of the frog There is the Kallidin I that isolated uterine can be made to shrink；Simultaneously as stone frog lower limb is stout and strong, delicious meat, is also that the delicious food on people's dining table is good Meat and fish dishes；So the stone frog has the highest edibility and medical value.But due to the seizure without restraint of the mankind, the stone frog day in nature Becoming to reducing, price constantly raises up, and wild resource destroys extremely serious, and many areas stone frog quantity is endangered.And due to the stone frog The market demand and economic worth, the artificial cultivation stone frog becomes necessary trend.

Technical staff, by studying the life habit of the stone frog and growth characteristics, gradually finds out a set of artificial cultivation The method of the stone frog, specifically comprises the following steps that

(1), the construction in stone frog pond

The aspects such as the artificial domestication stone frog, is become domestic from wild, living environment all there occurs that huge change, the stone frog are carried out manually Raise, must take reasonably to design to frog pond, make frog pond should be similar to natural environment, be easy to labor management again.Environment Quality directly affect growth promoter and the breeding of the stone frog, frog pond is not limited by place, and in general farming site preferably selects , irrigation and drainage convenience, environment quiet good in water quality, the most flooded, convenient management cool in summer and warm in winter, the non-irrigateiest, the anti-place escaping anti-evil.Support frog pond Can build indoor or outdoors in, indoor requirement is ventilated, and nice and cool, without sunlight direct projection, outdoor can set mat shelter, under build frog pond.Building the frog Before Chang, first reply water supply situation carries out probe, it is necessary to have abundant water resources, and the physicochemical property of water is suitable for the growth of the stone frog, in water Do not contain source of disease, near there is no polluter, water does not has or less containing source of disease.When designing drainage channel, should make each Frog pond can intake from inlet channel individually, and directly water can be entered gutter, can not make grown frog pool string and fill phenomenon, and this is favourable Spread and disease preventing and treating in preventing frog disease.Frog pond is divided into four types, is respectively suitable for the stone frog growth of different times.All kinds of frogs Pond, pond shape is preferably rectangle, and pond slanted floor 3～5 degree, osculum makes water thoroughly to be drained at lowest part, sets water in pond The things such as face, land, stone cave, food platform, the pond square that sets suitable for reading, to abscond in case leapfroging, harmful organisms is attacked.Water inlet pipe is arranged on pond Top, near the lower section of square.

(1) hatchery: area 1～2 m², pond height 0.5m, the depth of water 15～20cm, water quality is pure and fresh, pH6～8, and containing abundance Oxygen.

(2) Tinea Ranae pond: area 3～8 m², pond height 0.8m, the depth of water 3～10cm, pH6～7, land and water ratio 2: 1, need shading to raise Supporting, the Tinea Ranae of the same specification of a group is raised preferably in every pond.

(3) froglet pond: area 4～6 m², pond height 0.8m, the depth of water general 10～15cm, land and water ratio 2: 1, in pond lay 3～ The handstone of 5 centimetres, has built stone cave, and water quality is good, pH value 6～7.5.

(4) grown frog pool: area is generally 4～10 m²It is advisable, pond height 0.8m, pool inner water deep 10～20cm, face, pool inner water land Long-pending ratio is 3: 1, and is provided with the stone cave perched, and is covered with bigger cobblestone at the bottom of pond, and light is dark, and humidity keeps 80%, brings up one The ecological environment that preferably the stone frog perches, promotees its growth promoter, thus improves spawning rate and rate of fertilization.

(2) selection of the frog, is planted

4 annual～June is the egg production peak time of the stone frog, spawning rate to be improved, incubation rate, it is necessary to kind of frog hibernation recovery with After, before breeding breeding, carry out the selection of kind of the frog, breeding, lay eggs, the preparation such as hatching.Selecting kind of a frog is to do artificial breeding well The basis grown, after hibernation, to becoming the frog to check classification comprehensively before the spring is numerous, selects individuality relatively big, healthy and strong, skin light Slide, physically well develop, without disabled, without damaged, reach the sexually matured one-tenth frog and give over to kind of a use: general two age the female frog, body weight reach 150 grams with Upper property is the most ripe, and the male frog can be used as more than 200 grams kind, and primiparity Rana ovum is less, and the frog egg laying amount producing 1～2 time is higher, and quality is relatively Good, individual big aged frog egg laying amount is many, but poor quality, rate of fertilization is the highest, the most should not be elected to be kind of a frog, and the male frog requires strong Strong, kind jumping, skin light lower limb is strengthened；The female frog requires that short legs is thick, abdomen drum, skin light, 2～3 age kind frog reproductive capacity stronger.

(3), breed and lay eggs

After stone frog hibernation, follicle is grown rapidly, generally in April, starts breeding and lays eggs, terminate by the end of September during temperature more than 20 DEG C. Breeding female-male proportion is 1:1, plant frog pond breeding density be 15～20 every square metre, plant the frog typically when night 9 after embrace Right, the female frog of breeding ovulates when early morning 4～7, and output pieces of an egg usually adhere to stone pool wall, on pasture and water, lays eggs 300 the most every time ～500, high up to 1000～2000, ovum grain spheroidal, ovum grain is sticked together by ectoglia film, and the ovum of output is 1 The most do not stir within hour, in order to avoid pieces of an egg crush, reduce incubation rate, when the breeding of kind of the frog is laid eggs, if startled or by force Light irradiates, it will impact breeding, ovulates and is fertilized, and therefore, very important person is for one dim light of manufacture, peaceful, water quality is pure and fresh, water level Environment that is stable and that have the suitable breeding of running water and singing of the stream to produce, in daily raising operation more it should be noted that these.

(4), artificial incubation

Stone Rana ovum is spherical in shape, similar flake, ovum diameter about 2～3 millimeters, ovum outer layer glue, and plasma membrane is rounded, after ovum output is overboard, Cutose water suction is i.e. expanded, and ovum cutose is connected with each other into pieces of an egg, in botryoidalis, and pieces of an egg absorption stone in spawning pond, water Grass or pool wall on, unfertilized ovum after 3 days animal pole substantially turn yellow, vegetative pole White-opalescent, germ cell germinates to Ke Tadpole hatches, and the whole incubation period is the period that embryo sends out good, and embryo changes the most sensitive to external world, and this period requires environmental ecology Conditional stability avoids direct sunlight, and it is necessary careful manually to fish for during germ cell operation, light and slow, otherwise will reduce incubation rate.? In hatching process, water to clean, water temperature 23～28 DEG C, and pH value neutrality is advisable, and hatching density each hatching frame brood can not separate. Observing according to stone frog experiments of artificial incubations, stone Rana ovum 5～10 minutes after production, animal pole is black, and vegetative pole is white, the frog Ovum is hatched under 23～28 DEG C of water temperatures, and seen from the 5th day, germ cell animal pole stain is elongated in line, and within the 7th day, embryo is strip, and one End is big, one end is little, the 8th day embryo shapes evident from head and tail, Tinea Ranae, and can rock, and within the tenth day, just has a little Tinea Ranae to incubate Dissolving film, within the 13rd day, have 76% to hatch, within the 15th day, all hatch, incubation rate reaches more than 96%, and Rana ovum was hatched whole Cheng Zhongying accomplishes the technology requirements such as the sterilization of proper temperature, water nonpollution, Rana ovum, hatchery oxygen supplement.

(5), Tinea Ranae feeding and management

The stone frog is under Artificial feeding conditions, and after female frog lays eggs, its ovum can hatch Tinea Ranae through artificial incubation 10～15 days.Small tadpole Hatching rear health is brown color, body length 0.6～0.8cm.In drum hammer shape, generally absorption at the bottom of pond and on egg membrane, seldom movable, also Not looking for food, after three days, activity increases, and starts to look for food, and according to experimental observation, Development of Tadpole to experience: the initial stage, Early stage, mid-term, later stage four-stage.Later growth is also Larvae During Metamorphosis.The growth characteristic in Tinea Ranae each period and to raising The requirement of management is different.

(6), the feeding and management of froglet

Just abnormal froglet is small, and body length is less than one centimetre, and body weight is at about 2 grams, less than original Tinea Ranae, feed intake and Eupepsy is all not as good as the Tinea Ranae before metamorphosis, and froglet feedstuff has mobility's feedstuffs such as fly larvae, tenebrio molitor, Lumbricus.When throwing something and feeding of feedstuff Between between the lights before darkness, inventory depending on its feed intake, general keep pond in slightly bait residue be advisable.Froglet is at a monthly age Within feed fly larvae be main；One month later Lumbricus of can throwing something and feeding, along with growth and the increase of body weight of froglet age in days, is thrown something and fed Lumbricus also constantly to increase slightly, and the amount of feeding also to continue to increase.Just can throw such as the Lumbricus of chopsticks thickness after 2 monthly ages.Feed Note during froglet throwing in the bait lived on Sinl'Perca chuatsT eating on platform in pond, it is impossible to directly throw in water in order to avoid contaminant water Matter, and should grasp location, regularly, quantitatively, determine the principle of matter, before and after the every day of bait throwing between the lights, 5～7% by body weight are thrown Hello, also take the circumstances into consideration to increase and decrease, feed request wide variety because of Individual Size, appetite, weather, temperature, quantity simultaneously, fresh rich battalion Supporting, the carrying out of enough, few time is thrown something and fed, and to ensure frog comprehensive nutrition, grows rapidly, suffers from the disease less.Disable chloride tap water, change water Fixed depending on water temperature, change of water quality, when 20～26 DEG C, every day changes water once, and when temperature is more than 37 DEG C, the depth of water keeps 10～20cm, takes Running water is raised, and pond, feed table should carry out disinfection termly, and particularly high temperature in the busy season that frog activity is searched for food, more should carry out sterilization Anti-pre-operation with reduce disease generation, to froglet use breed in grades, carry out classification by the difference of the Individual Size of the frog, combine into Row is raised, and cultivation density typically rests in 100～300/square metre, and for rat preservative, frog pond suitable for reading adding covers screen window lid, prevent Abscond, carry out antifreeze sunstroke prevention work simultaneously.

(7) feeding and management of the frog is become

Become that frog management is upper takes lucifuge measure daytime it is noted that keep pond Zhou Anjing, dark, water deeply generally 10～ 15cm, water quality requirement is identical with tadpole period, disables chloride tap water, changes water depending on water temperature, change of water quality, every when 20～26 DEG C It changes water once；When temperature is more than 37 DEG C, the depth of water keeps 10～20cm, takes running water to raise, and pond, feed table should enter termly Row sterilization, particularly high temperature, in the busy season that frog activity is searched for food, more should carry out anti-pre-operation of sterilizing to reduce the generation of disease.

(7), the safe overwintering of the stone frog

Surviving the winter of Tinea Ranae can be carried out in indoor, and when water temperature is less than 10 DEG C, Tinea Ranae i.e. tends to resting state, do not eats motionless, dive in water In bedstone seam or thick grass, when surviving the winter, the depth of water keeps 20cm, uses perennial draingage, the antifreezing measures such as frog pond is added a cover, insulation, as there is water Surface freezes and then should be cracked in ice face, so that water body has certain oxygen exchange, is unlikely to make Tinea Ranae death by suffocation, froglet hibernation The general depth of water is about 15cm, is advisable not flooding cave, and leaves certain land, meets low temperature, freezing weather, also should mould Material thin film adds a cover heat-preserving anti-freezing measure, outdoor pond, and fine day can be raised thin film and irradiate by sunlight, and cover in the evening, and hibernation temperature is low Time be typically not required to feeding, temperature gos up, and the frog will come up activity, and has ingestion ability, now should give a small amount of feedstuff, to strengthen the frog Body constitution.Environment quiet should be kept when surviving the winter, defend harmful animal, prevent water quality from degenerating.

(8), frog disease preventing and treating

The generation that any frog is sick, is all various paathogenic factors and the frog body id reaction characteristic these two aspects phase interaction of external environment Result, pathogenicity strengthens along with the increase of environment undesirable element again.Ecological deterioration, frog body resistance declines, and some causes Pathogenic bacteria can be from the saprophytic parasitism (such as vibrio, Aeromonas) that is converted into, and virulence is strengthened.So whether frog disease occurs, not only depend on In the quality and quantity of pathogen, it is more dependent upon environmental quality and the resistance against diseases of frog body, therefore strengthens feeding and management work, be to prevent and treat disease Sick premise.Tinea Ranae breeding density to be controlled in period, often keeps water quality pure and fresh, and prevention occurs trichodinasis, gas bubble disease, fish molds Sick, hemorrhagic disease；Froglet and become frog period it is noted that often sterilize in frog pond, prevention red leg disease, gastroenteritis are sick, bark rot.

The specifically paathogenic factor of the stone frog includes three aspects:

(1), biological factor: include the biologies such as virus, antibacterial, parasite.In water environment in addition to there are some pathogenic microorganism, many Number is facultative pathogenic bacterium.At ordinary times, frog vibrio, Acarasiales, pseudomonas and oxygen Zymomonas mobilis etc. often and in breeding environment facultative cause bacterium Contact, though there being infection not fall ill, but along with the deterioration of environment, weakening of resistance, these antibacterials are converted into cause by not pathogenic Sick.

(2), environmental factors

Environmental factors not only affects Ranaspinosa David., also affects pathogenic organisms；If we meet the environmental condition needed for Ranaspinosa David., just Ranaspinosa David. resistivity can be strengthened；Relatively weaken the invasive ability of pathogenic organisms, the wherein temperature of water, acid-base value, dissolved oxygen；Sulfur Change the heavy metals such as hydrogen, the toxic gas such as methane, hydrargyrum lead, and pesticide etc., Ranaspinosa David. can be directly contributed and cause a disease or fatal.

The stone frog in breeding process it should be noted that problems with:

(1), breed Tinea Ranae the most on the spot and cultivate froglet, it is to avoid because strange land frog disease being brought into when shipping Tinea Ranae, froglet from other places.

(2), reasonable density breeding, carrying out " four fixed " bait throwing in is to strengthen its premunition, improves one of important measures of yield, " four Fixed " bait throwing in practice, also should according to season, weather, the frog ingest and growing state etc. suitably adjusts.

(3), strengthening daily management, keep frog pool environment health, duty patrols pond, finds that the state of an illness is treated in time, controls disease and sends out Open up and spread.

(4), catch, carry, when putting in a suitable place to breed should carefulness operation, prevent frog body injured.

(5), strengthen period management of surviving the winter, note water quality and temperature, and shortening is stopped eating the time as far as possible.

(6), the kind that premunition is strong is cultivated.
