Description

The earthen pond breeding method of Procambius clarkii
Technical field
The invention belongs to technical field of aquaculture, more specifically relate to the earthen pond breeding method of a kind of Procambius clarkii,
Background technology
Procambius clarkii (Procambarus clarkii), English name Red swampcrayfish is commonly called as lobster, cray etc., is the economic freshwater shrimps, because of the meat flavour deliciousness extensively popular to people.The market price constantly rises, and particularly these 2 years, wholesale price is the highest to reach 30 yuan of per kilograms, and supply falls short of demand.And also there is the problem (there is supply the 4-10 month) in the tangible period of slack sales in market.Thought in the past that this seed shrimp was an adventive, do not cause domestic research institution and promote the attention of office, therefore this shrimp is begun to specialize in to the whole process few people of breeding, breed from biology, seed is supply in batches not, culturing does not have regular carrying out, output mainly to rely on open-air the seizure yet, the price height after, natural resources quantity can be fewer and feweri, and the supply in market from now on must solve by breed.
The Ke Shi crayfish all has huge market at home and abroad, spell out in " the national fishery development 11th Five-Year Plan ": regional emphasis: traditional freshwater aquiculture zone of the Changjiang river and Basin of Huaihe River, give priority to that feedstuff feedings such as silver carp bighead, grass carp, megalobrama amblycephala are few, the filter food or the herbivorous fishes of stable yield, cultural technique maturation culture; Ominivore-fish breed such as carp are given priority in traditional freshwater aquiculture zone of the Huanghe valley, make up freshwater aquiculture product main producing region; Middle and lower reach of Yangtze River advantage is cultured the area, give prominence to production, the processing base construction of strong freshwater aquiculture kind such as the international competitive advantage of doing a good job of it river crab, eel, channel catfish, pearl freshwater mussel, freshwater crayfish; Big-and-middle-sized lake, the area that reservoir is intensive will utilize functional planning according to the waters, promote the three-dimensional culture of integrated ecosystem, carry out the comprehensive mode of production such as stock enhancement and cage culture; The area of eutrophication appears in the waters, should actively utilize water plants and filter-feeding aquatile to improve and the improvement water area ecological environment developing ecology repairing type aquatic products crop cultivation and aquaculture; The develop actively rice field fish culture is wanted in the southwest, rationally development reservoir fishery, the mountain area fish culture in running water of appropriateness.Therefore, the breed that we greatly develop the Ke Shi crayfish had now both met national planning, met the needs in market again.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the cultural method of a kind of Procambius clarkii is provided.
For achieving the above object, the present invention has taked following technical scheme:
The cultural method of Procambius clarkii comprises following technical step:
(1) pond transformation and level sterilization;
(2) close shrimp is put preceding preparation in a suitable place to breed;
(3) close shrimp is put in a suitable place to breed;
(4) feedstuff feeding;
(5) daily management;
(6) overwinter management;
(7) seed is cultivated
(8) seed catching;
Below each step in the technique scheme is described in detail:
1. pond transformation and level sterilization;
The preparation of ponds: the pond of raising Procambius clarkii requires to have abundant water resources, and water quality is good, advances draining conveniently, and will there be certain gradient in the pond, and area is advisable with 3-5 mu, depth of water 0.4-1.2m.
The pond of new excavation and the old pool to look feelings in addition at the bottom of the smooth pool, remove mud and shine the pool, make at the bottom of the pond and pool wall has good water retention property, reduce the seepage of Chi Shui as far as possible, preferably have some areas to resemble marshland, deep mixed, account for about the 1/3-1/5 of the pond gross area.Utilize the rice field to be transformed into the ditch that will carry out " well " font or sphere of movements for the elephants shape to the field on the pool, open the field degree of depth at 40-50 centimetre, width is at 3-4 rice, mound on the ridge in the outside, and compacting, require width more than 2 meters, and build the anti-facility of escaping well with materials such as asbestos shingle, plastic plate, films.
The place and the fish of shrimps activity are different, and the place of shrimps activity is to make its water body floor space of adhering to and the pasture and water cauline leaf in the pond, promptly can be big more in the water body for the area that shrimp adheres to, and the quantity that then can put shrimp in a suitable place to breed is many more.Procambius clarkii is liked perching at the cave shady place, and attachment can be placed certain quantity according to the condition of different regions, and we saw with tile and thick bamboo tube and are placed in the pond in the breeding farm of Australia state lobster, also can obtain same effect.
50%-70% left and right area plantation pasture and water are hidden the invasion and attack of harmful animal and perch usefulness for Procambius clarkii at the bottom of the pond when shell.Raise early stage when pasture and water do not grow, available terrestrial plant is bundled into grass being placed on around the pond, from 1.5m place, the ridge, pond, puts a branch ofly every 3-5m, puts 20-30 for every mu and restraints.
The sterilization of cleaning up the pond: the pond sterilization of cleaning up the pond, can effectively kill harmful organisms in the pond such as catfish, loach, snakehead, snake, mouse etc.; Strive wild fishes class such as carp, crucian and the pathogenic bacteria of food.Method commonly used mainly contains:
Lime disinfection: quicklime has the dry method sterilization and is with two kinds of water sterilizations.The dry method sterilization: the pond is stayed about water 10cm, uses quicklime 100-120kg for every mu, and full pool spilling head after shining the pool in 3-5 days, pours into new water again.Band water sterilization, every mu of water surface are with 1 meter calculating of the depth of water, and after usefulness quicklime 125-150 kilogram is soluble in water, evenly splash in full pond.
Bleaching powder is sterilized: after bleaching powder is dissolved fully, evenly splash in full pond.Consumption is every mu of 15-20 kilogram (containing available chlorine 30%), and the bleaching powder consumption reduces by half.
Some is local with the sterilization of cleaning up the pond of tea cake, and effect is also fine.Quicklime preferably is with foster freshwater shrimp, management that river crab is the same.
2. close shrimp is put preceding preparation in a suitable place to breed;
The plantation pasture and water; " shrimp how much, sees pasture and water " supports shrimp, survival rate height in the pond that pasture and water are many.The Procambius clarkii feeding habits are assorted, and the pasture and water that ingest have eel grass, hydrilla verticillata, Eichhornia crassipes, water lettuce and Alternanthera philoxeroides (water peanut), and the careless class of some Lu Sheng etc.Planting pasture and water in the pond, be the desirable place that shrimp provides hidden, perched, also is the good place of shrimp shell.The area of general plantation pasture and water is to be no more than 2/3 of the pond gross area.Also must put spiral shell well before putting in a suitable place to breed, every mu of requirement also needs later on progressively to add more than the 200-300 kilogram, only in this way could guarantee to support good lobster.
Water inlet and fertilising; The water source requires water quality pure and fresh, and the dissolved oxygen abundance is pollution-free.When Xiang Chizhong injects new water, to use 60-80 order filtered through gauze, prevent that wild fishes and fish-egg from entering in the raising pond with current, just finding this year has a large amount of small fish in the shrimp pool, feed all allows small fish eat, influence output, we find to have that to have in the pool, a family be the snakehead fish in a large number in addition, greatly the output of the lobster of influence.Plankton is cultivated in fertilising simultaneously.In the shrimp pond, apply fertilizer, preferably select organic manure for use, as execute the organic manure that fermented.Amount of application is every mu of 300-500 kilogram, makes the certain fertile degree of Chi Shuiyou.Put the initial stage preceding and that put in a suitable place to breed in a suitable place to breed at the shrimp seedling, the water level that Chi Shuiying control is more shallow, water quality is easily grown fat; In the middle and later periods of raising,, progressively increase fertilizing amount along with water level is deepened.Specifically to decide, keep water transparence at 35-40cm on water colour.
3. close shrimp is put in a suitable place to breed;
During close shrimp in this step is put in a suitable place to breed, be to the shrimp species quality requirement of putting in a suitable place to breed:
(a) specification: the shrimp species specification is more than 25 grams.Can put in a suitable place to breed simultaneously, also can put in a suitable place to breed in batches; (b) physique stalwartness, appendage is complete, and anosis nothing is hindered, and vitality is strong.
Put close shrimp in a suitable place to breed and also will pay special attention to the survival rate of shrimp, we have found a lot of problems in practical operation, put down and look at it is alive, can find mortality on the 2nd day.The death what reason causes? reason has good several respects: 1 in transportation dried up overlong time, make lobster be in dewatering state for a long time, be put in the pool that a large amount of suctions of lobster cause abdominal distension and dead.The seed of 2 purchases is put in poison in water body by household of fisher and captures, and putting into the pool can mortality.3 because means of transport is improper, causes the lobster extruding injured, puts Ren Tangzhong and also can cause mortality.
Cleaned up the pond back 7-10 days, pond water drug effect disappears, and just can put close shrimp.Put Miao Qianyao and carry out " trying the water ", if the shrimp of trying the water is movable normal.The no phenomena of mortality illustrate pond water property of medicine complete obiteration, can put in a suitable place to breed.
The time of putting in a suitable place to breed must be chosen in before October 15, in female shrimp maturing stage that is in egg development all of the big specification of this period, used so can be used as close shrimp.
4. feedstuff feeding
Freshwater crayfish feed stuff mainly is based on careless class, feeding habits are very similar to river crab, so planted grass is the key of having cultured lobster, requirement accounts for the above pasture and water of pond area 50-70%, we are to have planted a large amount of eel grass (shoulder pole grass) this year, other careless class is also passable, such as: heavy water and emergent aquactic plants such as hydrilla verticillata, waterweed, and some fluitantes.Also must put spiral shell well before putting in a suitable place to breed, every mu of requirement is more than the 200-300 kilogram, and also needing later on progressively is to add, and only in this way could guarantee to support good lobster.
In the reinforced cultivating process of Procambius clarkii parent shrimp, during the raising in the step was thrown something and fed, shrimp species can add the feed of animal origin reinforcement cultivation of part, the needs that satisfy the lobster breeding and survive the winter with pellet.
5. daily management
In the daily management of step, in the Procambius clarkii earthen pond breeding method very key a bit be the lifting of water level, be to stimulate the Procambius clarkii gonad development and the timely key of ovulation, therefore in daily management, can beat dried pond substantially, add new water then.
In the daily management of Procambius clarkii parent shrimp, adhere to every morning or make an inspection tour 1-2 time at dusk that observe the pond change of water quality, understanding Procambius clarkii food activity situation is done the adjustment of feedstuff feeding amount well; The cleaning breeding environment, unusual circumstance is in time taken measures.Daily management mission mainly concentrates on throws aspects such as feeding tube is managed, the water quality water level is regulated, mend spraying fertilizer, diseases prevention is prevented escaping.
6. overwinter management;
The overwinter management work of step concentrates on the water quality water level and regulates, and winter, water level will be controlled at the pond highest order, prevents from that the pond from freezing lobster in the hole is caused freeze injury, can add the part hay at the side of a pond, spreads out around along the ridge, the pool, plays insulation effect.
7. seed is cultivated
During the seed of the Procambius clarkii of step is cultivated, spring, the Procambius clarkii seedling can progressively break away from parent, at this moment want application in time, cultivate plankton, can throw something and feed soya-bean milk and partial crushing pellet make the shrimp seedling in time obtain prescribing adequate nutrition, can accelerate seed is growth, can early emerge, the production of shrimp seedling after also can not influencing so just can reach high yield and sufficient seedling morning is arranged.
8 seed catchings;
In the fishing for of step, Procambius clarkii seedling growth rate is very fast, and pond feed Procambius clarkii seedling through 1 month raising, becomes the shrimp specification to reach 6-8 when above, can fish for sale or moves the pool and culture into shrimp.
The method that Procambius clarkii is fished for is a lot, available lobster basket, instruments such as cage net, write by hand net catch, also can angle and catch, do the pond at last again and catch.
Seed is adopted lobster basket to rise and catches, and effect is better.
Compared with prior art, the present invention has following beneficial effect:
By testing method of the present invention, have this year a large amount of seeds to produce in our proving ground, on the one hand be we that each link is all held in breeding process is relatively good, we stay many ripe lobsters on the other hand.Though as lobster individual reproduction amount is not very big, survival rate after parent quantity is many, has just guaranteed the quantity of seed than higher.The Procambius clarkii breeding is nonsynchronous, and the seed size in same pond is inconsistent, produces needed seed but can breed, and can satisfy the needs of culturing from now on.Seed has in batches been arranged, and production development has from now on just had guarantee.
