Abstract
The present invention relates to a gender artificial-control technique of the cultivated fish, in particular to a gender control technique of the all-female-orientation of the salmon and bulltrout. Using the estrogen hormone to feed the normal fry transforms the male fry to be a fake-male fish with the female shape feature and the male physiological feature; using the sperm of the fake-male fish to fertilize the normal egg can realize that all offspring are female. When the fries of the salmon and bulltrout start to take food, the fries are fed with the feed containing methyl testosterone for three to six months and then the fries are fed with normal feed until the sex maturation. Selecting the fake-male fish with a female external morphological feature and a sex gland of the spermarium, taking out the spermarium, grinding the spermarium with a mortar, diluting the spermarium powder with the conventional sperm dilution, nursing the solution inside a refrigerator in four cent degrees for two to four hours, and then mating with the male fish to produce the all-female salmon and bulltrout. All fish output by the present invention are female; when in maturation, the ovary of the fish contains a plurality of fish roes that can be make into a featured dish or processed into the caviar, thereby improving the cultivation benefit.
Description
Technical field
The present invention relates to the sex Artificial Control method, particularly salmon trout class of cultured fishes, comprise rainbow trout, golden trout, Atlantic salmon and brook trout.Utilize the method for the full feminisation of salmon trout, producing all is female fish.Ovary in the female belly left and right sides contains bigger and more fish-egg when ripe, can make speciality as raw material, or be processed into caviar, improves culture benefit.
Background technology
Present salmon trout class of culturing, female and male sex ratio is 1: 1, or near 1: 1.Just in the marketable fish of culturing, have half or closely half quantity be male fish, the 5-15% of the spermary percentage of liveweight of adult fish owing to there is not value, then goes out of use, and has wasted the means of production.The full feminisation technology of existing salmon trout is to the fry female sex hormone of throwing something and feeding, and under functions of hormones, makes male fish that sex reversal take place, and becomes female fish.This technology has been prohibited aborning and has been used.The method of the full feminisation of salmon trout of our invention, at first cultivating genotype and be female, phenotype is male " false milter ", takes out the seminal fluid of " false milter " then, with normal female mating, offspring's sex of producing all is female.
Summary of the invention
When salmon trout seedling began to ingest, throwing something and feeding was doped with the feed of Methyltestosterone, continue to raise 3-6 month after, mix Methyltestosterone no longer in the feed transfers normal the raising to sexual maturity to.Selecting external form, to be characterized as female, sexual gland be spermary " false milter ", takes out spermary, grinds spermary with mortar, through the dilution of general spermatozoa diluent, in refrigerator under 4 ℃ of conditions child care 2-4 hour, discharge sperm, with female mating, produce complete female salmon trout then.
Embodiment
Consumption with 5-10ppm takes by weighing Methyltestosterone, is dissolve with ethanol more than 95% with purity, and Methyltestosterone and feed after the dissolving mix, and dry in the shade in the ventilation.
When salmon trout seedling had just begun to ingest, this feed that contains Methyltestosterone of throwing something and feeding continued to feed 3-6 month.Stop to feed Methyltestosterone then, change normal the raising into to sexual maturity.
In sexually matured individuality, select on form: lower jaw is longer than the upper jaw slightly, and the lower jaw front end is to upper process, and kiss is sharp; On physiology: " the false milter " of tool spermary.
Take out the spermary of " false milter ", grind spermary with mortar, (common prescription is NaCl 7.6g, KCl 2.98g, CaCl through general spermatozoa diluent
2.2H
2O 0.37g, MgCl
2.6H
2O 0.37g, NaHCO
30.21g adding distil water is to 1000ml) dilution, in refrigerator under 4 ℃ of conditions child care 2-4 hour.
Taking-up contains the dilution of sperm, and with ovum fertilization, the fish that hatches all is female.
Claims (3)
1. the method for the full feminisation of salmon trout is characterized in that adopting the Methyltestosterone of the 5-10ppm consumption salmon trout seedling of throwing something and feeding, and continues to raise 3-6 month, makes the normal female fry that sex reversal take place, and it is female becoming genotype, and phenotype is male " false milter ".
2. " the false milter " cultivated by claim 1 is characterized in that being longer than the upper jaw slightly for lower jaw on the form, and the lower jaw front end is to upper process, and kiss is sharp; Then be that the ovary reverse is spermary on the physiology.
3. " the false milter " picked out by claim 2, the feature of producing full raun method are to utilize " false milter " that sperm is provided, and the normal female fish provides ovum, produce whole female fishes behind sperm and the ovum fertilization.
