Abstract
The invention discloses a fast soft-shelled turtle breeding technology. The technology comprises the following steps of fast breeding soft-shelled turtle breeding, intensified antenatal breeding soft-shelled turtle breeding and soft-shelled turtle egg incubating. The fast soft-shelled turtle breeding technology has the advantages of being high in practicality, easy and convenient to operate and high in breeding benefit, the best advantage is that the breeding time from young soft-shelled turtles to spawning starting of the breeding soft-shelled turtle is shortened by about 1.5 years, the time when the breeding soft-shelled turtle lays eggs is earlier than that of convention by 20 days, and therefore the breeding process is accelerated, and the young soft-shelled turtle yield and benefits are improved.
Description
Technical field
The present invention relates to a kind of soft-shelled turtle fast breeding technical matters.
Background technology
The sexual maturity of soft-shelled turtle generally needed for four years, planted the spawning period of soft-shelled turtle at 5-6, and annual spawning season is the 5-9 month, and the busy season of wherein laying eggs is in early June-mid-August.At present, for the cultivation of kind of soft-shelled turtle, be all to carry out under nature, the cycle of production is long, and benefit is lower.For extending kind of a time for soft-shelled turtle spawning period, accelerate kind of a soft-shelled turtle and breed, improve culture benefit, must be to the cultivation technical matters of kind of soft-shelled turtle, carry out scientific and reasonable improvement.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of soft-shelled turtle fast breeding technical matters is provided, there is the feature practical, easy and simple to handle, culture benefit is high.
For achieving the above object, technical scheme of the present invention is: a kind of soft-shelled turtle fast breeding technical matters, 1) plant soft-shelled turtle and be bred as fast technology, 2) plant the antenatal reinforced cultivating technology of soft-shelled turtle, 3) soft-shelled turtle ovum hatching technique, described kind of soft-shelled turtle is bred as the aquaculture model that technology mainly adopts " greenhouse+outer pool " fast, this aquaculture model used for 2.5 years, can be by body weight 5g left and right soft-shelled turtle seedling, cultivate the kind soft-shelled turtle specification to body weight 1000g, the described kind of antenatal reinforced cultivating technology of soft-shelled turtle is mainly by improving cultivating pool water temperature to the transformation in pond, shorten the time of kind of soft-shelled turtle hibernation or half hibernation, kind of soft-shelled turtle is ingested in advance to recover physique and strengthens prenatal nutrition, for laying eggs, lay the foundation, described soft-shelled turtle ovum hatching technique comprises the preparation before laying eggs, the collection of soft-shelled turtle ovum, selecting and daily hatching management of fertilized egg, the matrix of hatching in described daily hatching management is particle diameter 0.5 ㎜～1 ㎜ vermiculite power, vermiculite bisque water content is controlled at 7%～8%, hatching house's relative air humidity is controlled at 75%～85%, 30 ± 2 ℃ of incubation temperatures, approximately 3600 ℃ of h of hatching accumulated temperature of fertilized egg, hatching lasts 40 days, during hatching, adopt pine to make the incubator box of 60 ㎝ * 12, ㎝ * 40 ㎝, case subdrilling treatment hole, first at the bottom of case, spread the wet vermiculite power of 2 ㎝～3 ㎝, fertilized egg is arranged on it, ovum spacing 1 ㎝ left and right, while putting ovum by animal pole upward, conventionally can arrange 2～3 layers, and then spread 3 ㎝～4 ㎝ vermiculite powers.
Described kind of soft-shelled turtle incubation technology fast adopts " greenhouse+outer pool " aquaculture model, the young soft-shelled turtle of selection body weight 5g left and right is put in a suitable place to breed in greenhouse and cultivates, cultivated for 1 year, until 5-6 month in next year is transferred to the outer pool and cultivates, cultivated for 1.5 years, body weight reaches 1000g and can be used as kind of soft-shelled turtle for laying eggs, than the time shorten 1.5 years of cultivating kind of soft-shelled turtle under natural conditions.
The described kind of antenatal reinforced cultivating technology of soft-shelled turtle comprises: (a) pond overlay film: build steel pipe arched roof on kind of soft-shelled turtle pond, play by the end of March every year covered with plastic film, to mid-May, throw off film, because cover film improves pond water temperature, impel kind of a soft-shelled turtle to ingest ahead of time, lay eggs; (b) prenatal nutrition: at the beginning of 4 months, plant in 15 days that soft-shelled turtle starts to ingest, take to throw and raise fresh fish feed as main, manufactured feed is auxiliary, to increase feed nutrition, improves kind of a soft-shelled turtle physique, lays eggs ahead of time.
Preparation before described laying eggs comprises the work of leveling of carrying out spawning ground, and scarifying vermiculite bisque, weeds a garden, and dredging drainage ditch, supplements vermiculite power, and the dry trickle of vermiculite power, makes it to keep moistening.
The collection of described soft-shelled turtle ovum comprises: check vermiculite bisque early morning every day, the discovery vestige of laying eggs, with bamboo let, carry out mark, the mark of root Ju the previous day on next day is adopted ovum, while adopting ovum, with finger, carefully pushs vermiculite power aside, takes out soft-shelled turtle ovum, and the animal pole of fertilized egg (circular white point) is emitted on upward and is adopted in ovum case, receive that ovum is complete has rearranged vermiculite bisque, if weather arid appropriate trickle, in order to close soft-shelled turtle again row lay eggs.
Selecting of described fertilized egg comprises: select fertilization sign obviously, ovum appearance is complete without damaged, the ovum that animal pole is clear or embryonic development is good.
The invention has the beneficial effects as follows: adopt " greenhouse+outer pool " aquaculture model to carry out parent culture, by build roof insulating above pond, in 3-4 month (days) and 9-10 month (end of the year) pond, temperature, water temperature can remain on more than 25 ℃, make parent in advance in normal production status, so not only shifted to an earlier date oviposition period, and prolongation laying period, thereby improve, produce seedling quantity, reduce parent's injures and deaths, and do not affect parent's merit, after parent is bred as, puts in a suitable place to breed in Wai Tang and cultivate and seed breeding, practical, easy and simple to handle, culture benefit is high.
