Abstract
The invention discloses the abductive approach that Dai-ju stock Pseudosciaena crocea is feminized, with estradiol 40 45 age in days Pseudosciaena crocea Fries are carried out with the induction production of hybrid seeds 42 days, it can be obtained by transformation system function raun, such method induction fish, which feminize, to be had many advantages, such as that female conversion ratio and survival rate are high, operate that easy, dosage is few, processing time is short and not aberration inducing.Basis and preposition technology can be provided for Larimichthys crocea and the nearlyer Sciaenidae unisexuality breeding of other affiliations.
Description
Technical field
The present invention relates to the breeding techniques of Larimichthys crocea, and in particular to the abductive approach that Dai-ju stock Pseudosciaena crocea is feminized.
Background technology
Larimichthys crocea (Larimichthys crocea), Perciformes, Sciaenidae, yellow croaker category are belonged in classification, is that cluster is whirled
The warm warm nature near sea fishes of trip, are mainly distributed on the marine sites such as China's the East China Sea, the Taiwan Straits and the South Sea.Cultivation at present
Larimichthys crocea mainly has 2 groups, and respectively Dai-ju stock Pseudosciaena crocea and east Guangdong Larimichthys crocea, Dai-ju stock Pseudosciaena crocea is distributed in because of it
The Dai Quyang and Lv Siyang of Zhoushan Fishing Ground and gain the name, have compared with east Guangdong Larimichthys crocea in the market body colour is yellow, build is good,
The features such as meat is excellent, popular with consumers, commodity value is high.With the gradually subdivision of Larimichthys crocea consumption market and secondary industry,
The presented trend for having moved towards different market channels of the Larimichthys crocea of different sexes, this is not only due to Larimichthys crocea male build more
It is good, directly as high-end gift fish and food and drink good merchantable brand, female individuals can utilize roe to develop deep processed product, more with consumer couple
The history sincerity of Wild Rhubarb fish and consumer form directly related.Rheum officinale fish culture and process mating industry have been equipped with carrying out
The Industry Foundation and the market demand of Larimichthys crocea monosex cultivation.At present, fish breeding has started based on fish sex and has determined that pattern is opened
The production of hybrid seeds of bill fish and breeding cultivation, receive the concern of aquatic products circle.But its production of hybrid seeds work originates in the induction of physiology Dot Blots Sex,
The large-scale production of unisexuality breeding could be realized by only realizing artificial sex induction.The research converted with hormone induction fish property
It starts from after estradiol is successfully synthesized and puts into production soon;According to display is had been reported, China is in Tilapia mossambica, yellow forehead
Sex induction research experiment is carried out in the cultured fishes such as fish, C. lazera, since kind is different, development time is different, processing
Method is different, and integrated conduct method is there are great difference, and induced efficiency is also significantly different.
Invention content
The technical problems to be solved by the invention are to provide the abductive approach that a kind of Dai-ju stock Pseudosciaena crocea is feminized, the induction
Method has many advantages, such as that female conversion ratio and survival rate are higher, processing time is short and not aberration inducing.
Technical solution is used by the present invention solves above-mentioned technical problem:The induction side that Dai-ju stock Pseudosciaena crocea is feminized
Method, its step are as follows:
A, estradiol with scrod feed is uniformly mixed, is configured to the pharmaceutical chemistry that estradiol content is 80~120mg/kg;
B, will hatching after 40~45 ages in days, body long size be 18~20mm, the above-mentioned pharmaceutical chemistry of the undifferentiated Pseudosciaena crocea Fry of sexual gland
It is fed 42 days instead of scrod feed, 22~25 DEG C of water temperature, salinity 22~24,1000~1500lx of illumination, pharmaceutical chemistry stop during feeding
Normal feeding management is carried out after feeding, you can obtains transformation system function raun.
Compared with prior art, the advantage of the invention is that the abductive approach that Dai-ju stock Pseudosciaena crocea is feminized, uses estradiol
40~45 age in days Pseudosciaena crocea Fries are carried out with the induction production of hybrid seeds 42 days, with regard to Ke to obtain transformation system function raun, such method induces
Fish feminize with female conversion ratio and survival rate be high, operation easily, dosage is few, processing time is short and aberration inducing etc. is not excellent
Point.Basis and preposition technology can be provided for Larimichthys crocea and the nearlyer Sciaenidae unisexuality breeding of other affiliations.
Specific embodiment
The present invention is described in further detail with reference to embodiments.
Embodiment 1
120mg estradiol is added to after the dissolving of 10ml ethyl alcohol as hormone working solution in 50ml ultra-pure waters, then weigh 1kg childrens
Fish meal is put in pallet, and the hormone working solution dissolved with estradiol is uniformly sprayed scrod feed, makes its final concentration of
The pharmaceutical chemistry of 120mg/kg is placed in 37 DEG C of drying 2h in baking oven, until ethyl alcohol volatilization packs refrigeration completely, after pharmaceutical chemistry drying.It chooses
The Dai-ju stock Pseudosciaena crocea fry of 40 ages in days 10000 feeds feed with pharmaceutical chemistry, and the time fed daily is 7:00、11:00、
15:00、20:00 point, feeding volume, which was subject in half an hour, to be eaten up, and it is primary respectively to change water sooner or later, quantity of exchanged water 50%-80%, continuous days
42 days.Daily management during nursery carries out without exception according to the method for Larimichthys crocea artificial propagation.Fry is shifted after induction
It is formed to marine net cage, chow diet is fed during forming, once in the morning and once at night, day feeding volume is the 3% of fish body weight.To big
The identification of yellow croaker gender mainly takes sexual gland to be determined with Histological method, and the property for feeding 150 days or so is taken to turn 31 tail of Pseudosciaena crocea Fry
(Body grows 14.00 ~ 23.5cm), it transports laboratory back and is dissected, gonadal tissue is taken to carry out microexamination, distinguishes male and female for the first time, it is female
Property rate be 96.77%.Quadratic search physiological raun genetic sex takes muscle of back tissue to carry out molecular specificity verification, specifically
Including DNA extractions-PCR amplification-agarose electrophoresis, as a result androgenetic individual ratio is 56.67% in physiological raun.
Embodiment 2
It is substantially the same manner as Example 1, the pharmaceutical chemistry of different only final concentration of 80mg/kg, selection be 45 ages in days Dai Qu
Race's Pseudosciaena crocea Fry.
Embodiment 3
It is substantially the same manner as Example 1, the pharmaceutical chemistry of different only final concentration of 100mg/kg, selection be 42 ages in days Dai Qu
Race's Pseudosciaena crocea Fry.
