Description
Technical field
The present invention relates to a kind of little yellow croaker breeding method, more specifically, it relates to the little yellow croaker training that a kind of ratio of female is high
Educate method and feedstuff feeding device.
Background technology
At present, under wild and cultivation state, little yellow croaker colony shows as the phenomenon that male quantity is significantly higher than female, and
Artificial breeding then wishes to obtain more females to ensure enough high-quality ovums.But the artificial breeding side used now
The little yellow croaker ratio of female that method obtains is relatively low, and bottom of pond is easily sunk to after feedstuff feeding, causes the waste of feed.
Chinese patent publication No. CN106577382A, disclose a kind of little yellow croaker family structure and breeding superior families side
Method, comprise the following steps：1st, little yellow croaker parent population obtains, 2, little yellow croaker family structure, 3, family standardization cultivate, 4, little yellow croaker man
It is fluorescence labeling, 5, the screening of fast-growth family.Can be by building little yellow croaker family, using standardization using the above method
Method carries out seed rearing, cultivates the later stage to family progress fluorescence labeling and carries out mixed breed, can effectively exclude different breeding
The influence that environment grows to family, it can accurately and efficiently filter out the family of fast growing.But this selection can not
Solve the problems, such as that the little yellow croaker ratio of female that artificial breeding obtains is relatively low.
The content of the invention
The little yellow croaker ratio of female obtained instant invention overcomes the artificial breeding method of use is relatively low, is easily sunk after feedstuff feeding
Enter bottom of pond, cause the deficiency of the waste of feed, there is provided a kind of ratio of female high little yellow croaker breeding method and feedstuff feeding device,
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 that to lure and stimulate to little yellow croaker, be easy to be captured by little yellow croaker, prevent feed from sinking to bottom of pond and causing to waste.
In order to solve the above-mentioned technical problem, the present invention uses following technical scheme：A kind of high little yellow croaker of ratio of female is cultivated
Method, comprise 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 fed in little yellow croaker culture pond, continuously feed 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 the age in days of little yellow croaker 15, cooked egg yolk is taken
Going out, load 80 eye mesh screens and wash by rubbing with the hands, gained egg yolk suspension is used to feed little yellow croaker, after the age in days of little yellow croaker 20,60 mesh sieves of yolk
Net is washed by rubbing with the hands, and the yolk for obtaining bigger particle diameter feeds little yellow croaker 10 days；C, mid-term is cultivated, and after the age in days of little yellow croaker 30, 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, and artifical compound feed is fed to 90 ages in days after 40 ages in days；D, the later stage cultivates, after the age in days of little yellow croaker 90,
Culture pond water temperature is recovered to normal seawater water temperature, continues to feed artifical compound feed.
During 90 age in days of little yellow croaker cultivated by this method, take sexual gland to carry out paraffin section observation, count 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
Spend low temperature to cultivate, advantageously occur in the differentiation of little yellow croaker female gonads.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.
