The technique for rearing the crayfish seedling has beneficial effects that: the quality of crayfishes can be improved, and popularization of the intergrowth of the crayfishes and paddies can be realized.
Description
Technical field
The present invention relates to the raising fish and shrimp field, be specifically related to the cultivation technology of cray seedling.
Background technology
Known fishes and shrimps are all lived in waters such as rivers, Hu Hai, pond, and wherein fresh water shrimp is lived in waters such as rivers, pond, ditch more, its growth, breeding, all be spontaneous, from numerous.
In recent decades, be seated in the Qianjiang administrative region of a city of Jianghan Plain central area, Hubei Province, the peasant cultures a kind of fresh water shrimp in the rice field, and the locals is called cray, can in simple rice field, grow, breed, and forms a kind of ecological circulation of shrimp rice symbiosis of uniqueness.Since support shrimp with plant rice can symbiosis, and foster shrimp not only do not influence the output of paddy, also supports shrimp for vast farmers in a large number in the rice field and opened up the wide new way of getting rich.The nearly more than ten years; Wide-spread; The food nutrition of making is abundant, delicious nice; Very fiery with cray as restaurant, the restaurant of Speciality Foods on the dining table; Thereby to the demand of cray seedling supply falls short of demand; Its raising of cultivating technology is more and more outstanding; And general peasant household takes the rice field both coarse slow from being conigenous numerous type of rearing; Not only can not improve the quality of seedling; Also can't satisfy the demand of vast rice field zone peasant, this drawback never had the good technical scheme solve the cray seedling.
Summary of the invention
The cultivation technology of cray seedling of the present invention; Solved above-mentioned drawback well; Its purpose just provides a kind of cultivation technology of cray seedling of science of standard; To promoting zone, rice field peasant the demand of rice shrimp symbiosis seedling has been played huge impetus; Its technology has solved cray distant relative mating, outbreeding, scientific culture, the foster rapid-result cultivating management technology of speed well; For a large amount of shrimp rice symbiosis, promote seedling rapidly, the technical scheme of Yi Xueyi meeting is provided.
Be the purpose of the cultivation technology that reaches cray seedling of the present invention, the inventor successfully sums up the cultivation technology of seven science through for many years breed, research, analysis:
One, choosing is built and is cultivated the place
1. selection is ecological good, and periphery is quiet, closes on the water source, water yield abundance, and irrigation and drainage are convenient, free of contamination cultivation place, water source.
2. build 2000-3000 square metre cement pit, dark 1.5 meters of pond, above 0.5 meter inwall smooth, prevent the lobster flight.The ridge, the pond ratio of slope is 1: 2.5～3, and is smooth at the bottom of the pond, builds up into, pumping equipment.
3. after cement pit is built up, irritate 0.2 meter water earlier, at the bottom of pool wall and pond, splash, reach the effect of thorough disinfection with the Eusol of 10 mg/litre concentration.
4. go out the water-based plant what some was transplanted or thrown in to cement pit; Supply cray to climb when perching as the sheltered situation with shell; Some pasture and water can also be as the bait of cray; The capacity 5%-35% that accounts for water is advisable; And put some net sheets, plastic barrel, tile etc., increase that cray perches, shell and hidden place.
5. water quality is pure and fresh, putting will intake before the shrimp reach 1.4 meters dark, intake with screen filtration at water inlet, prevent that harmful animals such as insect, small fish and frog's egg from getting in the ponds.Water temperature is at 24 ℃～28 ℃, and it is steady in a long-term that water temperature is wanted.
Two, the science mating is bred
1. in the temperate zone or the natural waters of subtropical zone, the cray sexual maturity is before and after October, and body length is at 10-15 centimetre, per kilogram 25-40 tail, the breeding season May in every year to September.Cray become pregnant, lay eggs, breed multiple factor affecting such as being subjected to water temperature, water quality, spring, summer, Qiu Sanji all have the cray phenomenon of laying eggs, so, just have the cray of plurality of specifications individual in natural waters.
2. in order to guarantee the quality of cray seedling, in breeding, must select the seed shrimp of body length, body weight basically identical, its bodily form will normally not have deformity, the complete N/D of podomere, and shrimp body gloss is distinct, and meat is full, and is rapidly movable; The annual wild shrimp and the tame shrimp mating of raising in the pond that will in rivers, lake, fish for some keeps the steady quality of shrimp species.
3. the seed shrimp pond must be built separately, and female seed shrimp 24-48 kilogram should be thrown in 1000 squares of ponds, public seed shrimp 12-24 kilogram, and female-male proportion is 2: 1.
4. before and after public seed shrimp and the female seed shrimp mating, cray can be burrowed in the bed mud soil of pond, and female seed shrimp lays eggs and accomplishes in the cave with the incubating oosperm process is many.Female seed shrimp 300-500 grain of can laying eggs, water quality factors such as its fertilized egg hatching and water temperature, water-soluble oxygen amount and transparency have direct relation, and water temperature is in the time of 22 ℃～29 ℃, and cray hatches juvenile prawn and leaves the about 30-40 of parent days from laying eggs.The young shrimp that female seed shrimp hatches must be attached in the body oogenesis chamber and live about 20 days, when developing into juvenile prawn, just can leave parent and live on one's own life.
5. when juvenile prawn leaves parent and occurs in a large number, must fish for juvenile prawn, drop in the juvenile prawn pond in batches and raise with the cage net; Also right in batches fishing for shrimp on public affairs are long-pending and female seed shrimp rendered in the other seed shrimp pond.
Three, science is put juvenile prawn in a suitable place to breed
1. the juvenile prawn density of putting in a suitable place to breed is generally at every square metre 500～800 tail.
2. juvenile prawn put in a suitable place to breed should be in lower morning of temperature or at dusk, mouthful shallow water pasture and water district input of being in the wind.Action wants light during input, slowly drag dress shrimp instrument submerged backward juvenile prawn is put into water.
3. the juvenile prawn specification in the same pond is consistent basically, and individual difference can not be too big.
Four, science is raised juvenile prawn
1. after juvenile prawn went into the pond, the beginning manual work was thrown something and fed.The last week, the bait of throwing something and feeding has Rice & peanut milk, the soya-bean milk that grinds, and every day, feeding volume was about 0.1 kilogram of bait of per ten thousand tail juvenile prawns.Threw something and fed at full pool spilling head with about 5 o'clock at dusk about 10 o'clock every mornings.Concrete feeding volume also will be grasped according to the situation of ingesting of weather, water quality and shrimp flexibly.
2. the bait sunny day is thrown foot, sultry day, overcast and rainy few the throwing.Water transparency was thrown in time more than 30 centimetres more, and after throwing something and feeding several days, water transparency obviously reduces, and it is out of condition to illustrate that juvenile prawn ingests, and should reduce feeding volume.
3. after the week, use small fish and shrimp, earthworm, spiral shell freshwater mussel meat, fish meal etc. instead and sneak into corn, wheat and be broken into the pasty state material repeatedly and throw something and feed.The throwing amount is 10% of a shrimp body weight, simultaneously, and alternately throw something and feed fresh bean dregs and soaked grouts.In addition, when throwing something and feeding animal bait, in order to guarantee comprehensive nutrition, the green forages such as some browses, dish leaf of can throwing something and feeding on a small quantity every day; Juvenile prawn was raised after one month, and the shrimp body is healthy and strong, can put into rice field and paddy symbiosis.
Five, water quality management is important
1. in the juvenile prawn cultivating process, the water in juvenile prawn pond must keep water quality pure and fresh, and dissolved oxygen is sufficient, and the dissolved oxygen content in the water remains on more than 5 mg/litre.
2. Chi Shui will keep totally, and dirt, residual bait will in time be removed in the pond, refreshes the water periodically, blowdown, oxygenation, keeps good water quality.
Six, prevention harmful animal poisoning
1. the nurturing period, often look the pond, the active situation of juvenile prawn every day is carried out record, and the variation of water quality in the claire at any time.To the harmful organisms that occurs in the pond,, in time catch or knock out like snake, mouse, frog, fish, birds etc.
2. prevent the inflow of agricultural chemicals, particularly pyrethrins or pyrethroid pesticide.Therefore, the periphery in the shrimp pond forbids to use high poison, persistent pesticide such as decis, speed are killed, cypermethrin organic phosphor.
Seven, prevention diagnose and treat diseases
1. often remove mud too much in the pond, in the pond in the mud organic matter too much, when water temperature raise, organic matter can rot to produce harmful substances such as toxic gas such as a large amount of hydrogen sulphide, methane and organic acid, ammonia, nitrogen, poisons cray.
2. the pond middle water level is too shallow, can cause the sudden change of water temperature, juvenile prawn can not be adapted to and ill, causes death when serious, notices that water often keeps high-order in the pond.
3. can not in the pond, inject sewage, sewage can be brought a large amount of pathogenic germ harm juvenile prawns into.
4. juvenile prawn likes eating fresh bait, as the bait unclean or that rot of throwing something and feeding, and can make water quality deterioration grow germ, causes the cray morbidity.
5. carry out the sterilization of cleaning up the pond, the sterilization of the shrimp body when throwing in seed and daily water body disinfection.
6. disease that juvenile prawn takes a disease,, crayfish pestilence unsuccessful like soft-shell disease, sick, the black gill disease of mashed shell, balantidiasis, hemorrhage, saprolegniasis, shell etc. all will be suited the remedy to the case.
The quality of the useful cray of present technique improves and the large tracts of land of shrimp rice symbiosis is promoted.

Four, science is raised juvenile prawn
1. after juvenile prawn went into the pond, the beginning manual work was thrown something and fed.The last week, the bait of throwing something and feeding has Rice & peanut milk, the soya-bean milk that grinds, and every day, feeding volume was about 0.1 kilogram of bait of per ten thousand tail juvenile prawns.Threw something and fed at full pool spilling head with about 5 o'clock at dusk about 10 o'clock every mornings.Concrete feeding volume also will be grasped according to the situation of ingesting of weather, water quality and shrimp flexibly.
2. the bait sunny day is thrown foot, sultry day, overcast and rainy few the throwing.Water transparency was thrown in time more than 30 centimetres more, and after throwing something and feeding several days, water transparency obviously reduces, and it is out of condition to illustrate that juvenile prawn ingests, and should reduce feeding volume.
3. after the week, use small fish and shrimp, earthworm, spiral shell freshwater mussel meat, fish meal etc. instead and sneak into corn, wheat and be broken into the pasty state material repeatedly and throw something and feed.The throwing amount is 10% of a shrimp body weight, simultaneously, and alternately throw something and feed fresh bean dregs and soaked grouts.In addition, when throwing something and feeding animal bait, in order to guarantee comprehensive nutrition, the green forages such as some browses, dish leaf of can throwing something and feeding on a small quantity every day; Juvenile prawn was raised after one month, and the shrimp body is healthy and strong, can put into rice field and paddy symbiosis.
Five, water quality management is important
1. in the juvenile prawn cultivating process, the water in juvenile prawn pond must keep water quality pure and fresh, and dissolved oxygen is sufficient, and the dissolved oxygen content in the water remains on more than 5 mg/litre.
2. Chi Shui will keep totally, and dirt, residual bait will in time be removed in the pond, refreshes the water periodically, blowdown, oxygenation, keeps good water quality.
Six, prevention harmful animal poisoning
1. the nurturing period, often look the pond, the active situation of juvenile prawn every day is carried out record, and the variation of water quality in the claire at any time.To the harmful organisms that occurs in the pond,, in time catch or knock out like snake, mouse, frog, fish, birds etc.
2. prevent the inflow of agricultural chemicals, particularly pyrethrins or pyrethroid pesticide.Therefore, the periphery in the shrimp pond forbids to use high poison, persistent pesticide such as decis, speed are killed, cypermethrin organic phosphor.
Seven, prevention diagnose and treat diseases
1. often remove mud too much in the pond, in the pond in the mud organic matter too much, when water temperature raise, organic matter can rot to produce harmful substances such as toxic gas such as a large amount of hydrogen sulphide, methane and organic acid, ammonia, nitrogen, poisons cray.
2. the pond middle water level is too shallow, can cause the sudden change of water temperature, juvenile prawn can not be adapted to and ill, causes death when serious, notices that water often keeps high-order in the pond.
3. can not in the pond, inject sewage, sewage can be brought a large amount of pathogenic germ harm juvenile prawns into.
4. juvenile prawn likes eating fresh bait, as the bait unclean or that rot of throwing something and feeding, and can make water quality deterioration grow germ, causes children's morbidity.
5. carry out the sterilization of cleaning up the pond, the sterilization of the shrimp body when throwing in seed and daily water body disinfection.
6. disease that juvenile prawn takes a disease,, crayfish pestilence unsuccessful like soft-shell disease, sick, the black gill disease of mashed shell, balantidiasis, hemorrhage, saprolegniasis, shell etc. all will be suited the remedy to the case.
