Description
Technical field
The utility model relates to aquaculture fields, and in particular to a kind of cray batch production spawning and hatching device.
Background technique
Cray, scientific name Procambius clarkii (Procambarus clarkii), also known as red marsh crayfish, cray or
Lead and cadnium originates in northern Mexico and southern US, and Crustachia, Decapoda, Astacidae, original are subordinate in Zootaxy
Astacus, live in freshet, lake, reservoir, pond, streams, marsh, in irrigation canals and ditches.It is transplanted within 1918 Honshu of Japan,
Nanjing is about introduced by Japan in phase later 1930s, starts to multiply in Nanjing and its suburbs and counties under the jurisdiction of a large city later；Due to the shrimp
Wide adaptability, vitality and reproductive capacity are strong, not high to water quality requirement, quickly throughout each corner of the Yangtze river basin.It is complete at present
The small cultivation of the small dragon of state is a piece of red as fire, and national cultured area in 2016 is more than 9,000,000 mu, and 85.23 ten thousand tons of cultured output, the output value
564.10 hundred million yuan, the economic gross output value 1466.10 hundred million, complete nearly 5,000,000 people of industrial chain practitioner, for the life of the world's largest cray
Produce state.In recent years, China cray is constantly in the state that supply falls short of demand.
In cray aquaculture industry chain, breeding shrimp seedling link is the most important thing.The modes of reproduction of cray has it certainly
The particularity of body, it may be assumed that dig a hole, a female or two female one male inhabitations want oogenesis, the young is still without departing from mother after hatching after oviposition
Body, female shrimp is without departing from cave during breeding.There are mainly three types of the modes for obtaining cray seed at present: first is that natural pond is numerous
It grows.The breeding of natural pond refers in the pond of cultivation cray, allows its nature under conditions of not increasing any artificial measures
Breeding, to achieve the purpose that cray is proliferated.Its method is: being leveled before close shrimp is launched to pond, except wild, disinfection is applied
Fertilizer, plantation water plant, then launch close shrimp, close shrimp are allowed to burrow, into hole in voluntarily breed；To March in next year, cray is just had
Cave is left, ingests out, activity, starts to feed and catch into shrimp at this time.This propagation method is suitable for small lakes, marsh
The biggish pond of ground, area and low-lying rice field；It can also be used for the biggish intensive fish pond of area；For plant-type lake, seed shrimp is put into
Grass and fertilising need not be then planted afterwards.Natural pond breed the shortcomings that be: low output, can only this pond use, it is impossible to be used in Seedling production.
Second is that half-manual breeding.Half-manual breeding refers to be controlled by artificial part, to achieve the purpose that cray breeds.Its method
It is: puts in a suitable place to breed and first breeding pool leveled before close shrimp, sterilized, except open country, then launches the close shrimp by selecting.Keep good
Water quality, periodically fills new water, feeds the water plants such as the higher bait of some animal protein contents and water hyacinth more, can build
The greenhouse of sunshade promotes mating the parent shrimps, oviposition by Factors such as manual control temperature, illumination, water quality, water levels.It is this numerous
Mode is grown suitable for pond culture.The shortcomings that half-manual breeding is: low output is unable to meet production demand.Third is that full artificial breeding
It grows.Refer to that breeding overall process all reaches predetermined purpose by artificially controlling.This reproductive modes controllability and operability are stronger,
It is substantially carried out in cement pit indoors, has many advantages, such as that density is big, yield is high, high survival rate.Its method is: cement water
Body is 80 centimetres or so deep, the settable a large amount of artificial nest in bottom, such as finger stone, tile, hangs a small amount of water plant such as water calabash
Reed, water peanut, bog pondweed, hydrilla verticillata etc. induce small dragon by a series of control illumination, the measure of water temperature, water quality, water level
Shrimp mating the parent shrimps, oviposition.But the seedling raising manners of this complete artificial batch production are only being tested currently without being succeeded
Stage.Its major defect is: environmental condition and natural environmental condition great disparity are too big, and the spawning and hatching rate of cray is all lower.
Utility model content
In view of the drawbacks of the prior art, the utility model provides a kind of cray batch production spawning and hatching device, basis
The special modes of reproduction of cray simulates nature cave, artificial to manufacture more perfect, comfortable, reliable artificial cray oviposition
Hatching house provides advantageous environmental condition for the breeding of cray, increases substantially the spawning and hatching rate of cray.
The technical solution of the utility model is: including workshop and the cray spawning and hatching pond being laid in inside workshop, small
Lobster spawning and hatching room；Cray spawning and hatching pond is used equipped with water inlet pipe, drainpipe and the cement pit for being oxygenated pipe, pond
Bottom, pool wall cover two layers of mesh adhered to and climbed convenient for cray, put suitable water plant, the top of pool wall in a suitable place to breed in water body
Anti-escape shading cloth equipped with certain altitude；Cray spawning and hatching room is set in cray spawning and hatching pond, and cray produces
Egg hatching room uses plastic tube, and plastic tube is disposed vertically in cray spawning and hatching pond bottom of pond or in the ad hoc platform in the top of bottom of pond
It places, the both ends of plastic tube are smooth and port is vertical with pipe shaft, and pipe shaft is equipped with several apertures for water body exchange, plastic tube
Inner wall is with one or two layers convenient for the mesh of cray disengaging climbing, and the bottom end of plastic tube is closed with mesh, same seat
The height of cray spawning and hatching room in cray hatchery is consistent, the top certain distance dew of cray spawning and hatching room
The water surface out, cray spawning and hatching room accumulation regions top are equipped with the inclined climbing slope surface for facilitating cray to pass in and out into water, climb
Bait platform is arranged in the middle part in climbing face.
Above-mentioned technical proposal can advanced optimize are as follows:
Cray spawning and hatching pond is additionally provided with heater.
The cray spawning and hatching tank depth 100cm；The height 60-90 cm of cray spawning and hatching room, wherein being located at
The 20-30 cm on top exposes the surface.
Anti-escape shading cloth height above cray spawning and hatching pond is 20cm, and material uses plastic cloth.
The kind of the water plant uses water peanut, waterweed and water hyacinth；The area of water plant covering accounts for the 2/3 of the water surface.
The mesh uses screen of screen window or bolting silk net.
Cray spawning and hatching room is set as several rows, be distributed in the one side in cray spawning and hatching pond, two sides, three faces,
Surrounding or centre, distribution area account for the 1/3 of cray spawning and hatching pond internal area.
The plastic tube uses PVC plastic pipe.
The internal diameter of the plastic tube is 63-75mm.
The utility model has the following beneficial effects:
1. using simulation design, cray spawning and hatching room places oneself in the midst of cray seemingly naturally like natural cave
In environment, one female one male or two female one male requirements, it is latent can to give full play to cray breeding when meeting cray spawning and hatching
Power, it is ensured that cray realizes good spawning and hatching rate.
2. it is structurally reasonable, it is easy to operate.
3. materials are easy, cost is relatively low.
4. it is practical, there is important demonstration and promotional value.
