The invention discloses a kind of little yellow croaker breeding methods and feedstuff feeding device that ratio of female is high, it is intended to which the little yellow croaker ratio of female for solving the artificial breeding method used acquisition is lower, is easy to sink to bottom of pond after feedstuff feeding, causes the deficiency of the waste of feed.The invention is the following steps are included: a, seed rearing, little yellow croaker open-mouthed bait wheel animalcule carry out fortification after little yellow croaker membrane 5 days with soya-bean milk and pull the wheel animalcule after fortification out and feed in little yellow croaker culture pond, continuously feed 10 days；B, early stage cultivates, and starts to feed yolk after 15 age in days of little yellow croaker；C, mid-term is cultivated, and after 30 age in days of little yellow croaker, culture pond water temperature is controlled at 20-22 degrees Celsius, wherein feeding the fairy shrimp strengthened by soya-bean milk after 30 ages in days to 40 ages in days, feeds artifical compound feed to 90 ages in days after 40 ages in days；D, the later period cultivates, and after 90 age in days of little yellow croaker, culture pond water temperature is restored to normal seawater water temperature, continues to feed artifical compound feed.
Description
Technical field
The present invention relates to a kind of little yellow croaker breeding methods, more specifically, it relates to which a kind of little yellow croaker that ratio of female is high is trained
Educate method and feedstuff feeding device.
Background technique
Currently, little yellow croaker group shows as the phenomenon that male quantity is significantly higher than female under wild and cultivation state, and
Artificial breeding then wishes to obtain more more females to guarantee enough high-quality ovums.But the artificial breeding side used now
The little yellow croaker ratio of female that method obtains is lower, is easy to sink to bottom of pond after feedstuff feeding, causes the waste of feed.
Chinese patent publication No. CN106577382A discloses a kind of building of little yellow croaker family and breeding superior families side
Method, comprising the following steps: 1, the acquisition of little yellow croaker parent population, 2, the building of little yellow croaker family, 3, family standardization cultivation, 4, little yellow croaker man
It is fluorescent marker, 5, the screening of fast-growth family.It can be by constructing little yellow croaker family, using standardization using the above method
Method carries out seed rearing, cultivates the later period to family progress fluorescent marker and carries out mixed breed, can effectively exclude different breeding
The influence that environment grows family can accurately and efficiently filter out the family of fast growing.But this selection can not
The little yellow croaker ratio of female for solving the problems, such as that artificial breeding obtains is lower.
Summary of the invention
The little yellow croaker ratio of female obtained the present invention overcomes the artificial breeding method of use is lower, and it is heavy to be easy after feedstuff feeding
Enter bottom of pond, cause the deficiency of the waste of feed, provides a kind of little yellow croaker breeding method and feedstuff feeding device that ratio of female is high,
The little yellow croaker ratio of female that the breeding method obtains is high, and artificial breeding can obtain more high-quality ovums.Feed is floated to be fed,
Have the function of luring and stimulate to little yellow croaker, convenient for being captured by little yellow croaker, prevents feed from sinking to bottom of pond and cause to waste.
In order to solve the above-mentioned technical problem, the invention adopts the following technical scheme: a kind of little yellow croaker that ratio of female is high is cultivated
Method, comprising the following steps: a, seed rearing, little yellow croaker open-mouthed bait wheel animalcule carry out fortification, little yellow croaker membrane 5 with soya-bean milk
After it, the wheel animalcule after fortification is pulled out and is fed in little yellow croaker culture pond, continuously feeds 10 days, once in the morning and once at night, cultivate
Wheel animalcule is no less than 5/milliliter in pond；B, early stage cultivates, and starts to feed yolk after 15 age in days of little yellow croaker, cooked egg yolk is taken
Out, 80 mesh screens being packed into wash by rubbing with the hands, gained egg yolk suspension is for feeding little yellow croaker, after 20 age in days of little yellow croaker, 60 meshes of yolk
Net is washed by rubbing with the hands, is obtained more large-sized yolk and is fed little yellow croaker 10 days；C, mid-term is cultivated, and after 30 age in days of little yellow croaker, will cultivate water
Temperature control system is at 20-22 degrees Celsius, wherein the fairy shrimp strengthened by soya-bean milk is fed after 30 ages in days to 40 ages in days, the good year in culture pond
Worm is no less than 8/milliliter, feeds artifical compound feed to 90 ages in days after 40 ages in days；D, the later period cultivates, after 90 age in days of little yellow croaker,
Culture pond water temperature is restored to normal seawater water temperature, continues to feed artifical compound feed.
When 90 age in days of little yellow croaker cultivated by this method, sexual gland is taken to carry out paraffin section observation, counts female-male proportion
For 22:8, ratio of female is about 73.33%.Ratio of female 40% compared to Normal group is significantly increased.Contain in soya-bean milk and yolk
There are a large amount of oestrogen-mimickings, can induce fry and break up towards female gonads, and -90 age in days little yellow croakers on the 30th are Celsius in 20-22
It spends low temperature to cultivate, the differentiation for being more conducive to little yellow croaker female gonads occurs.And soya-bean milk and the harmless noresidue of yolk health.This
The little yellow croaker ratio of female that the high little yellow croaker breeding method of kind ratio of female obtains is high, and artificial breeding can obtain more high-quality ovum
Son.
Preferably, when wheel animalcule carries out fortification with soya-bean milk in step a, it is laggard by the immersion of soya bean clear water 10-15 hours
Row juicing, using the screen to filtrate, gained soya-bean milk is uniformly spilled into wheel animalcule growth water body, every 10 tons of water with 80-150 grams of soya bean,
Wheel animalcule density 5-10 × 10 in water body8A/ton, enhanced time 12 hours or more.The fortification that wheel animalcule is carried out using soya-bean milk, is had
Break up conducive to induction fry towards female gonads.
Preferably, 10 yolk are washed by rubbing with the hands with 5 liters of water in step b, it can be used for feeding little yellow croaker 8000-10000 tail, sooner or later
10 yolk are respectively fed, divides equally 3-5 times sooner or later and feeds, are spaced 30 minutes.Yolk is fed sooner or later, and is divided 3-5 times and fed completion 10
A yolk is conducive to egg yolk granule and is sufficiently obtained by little yellow croaker, avoids wasting.
Preferably, artifical compound feed is mixed with soya-bean milk in step c and d, every kilogram of artifical compound feed is with 10-20 grams
Soya-bean milk stirs evenly, and is used further to feed little yellow croaker after air-drying.With being fed again after soya-bean milk and artifical compound feed mixing, favorably
In the ratio of female for improving little yellow croaker.
Preferably, when fairy shrimp carries out fortification with soya-bean milk in step c, after soya bean clear water is impregnated 10-15 hours
It squeezes the juice, using the screen to filtrate, gained soya-bean milk is uniformly spilled into fairy shrimp growth water body, and every 10 tons of water is with 100-200 grams
Soya bean, fairy shrimp density 6-15 × 10 in water body8A/ton, enhanced time 12 hours or more.The battalion of fairy shrimp is carried out using soya-bean milk
It supports and strengthens, be conducive to that fry is induced to break up towards female gonads.
A kind of feedstuff feeding device of the little yellow croaker breeding method high for ratio of female, including be securedly mounted on culture pond
Bracket, liftable adjusting is connected with connecting column on bracket, and several connecting rods are uniformly connected on connecting column, connects boom end
It is fastenedly connected drainage pipe, the arc-shaped structure of drainage pipe, drainage pipe internal diameter is gradually reduced from one end to the other side, drainage tube
