“Fish” has been widely used in popular culture abroad. Because males.
The colorful beauty. It also has long ears and large fins than females. Of this type is used.
Fight for sport and gambling. The male is more popular in the culture.
But the study found that the ratio of male and female.
Breeding is one of the first kind to the fish.
Distribution must learn the proper techniques for breeding.
And cost to get the gender that meets the needs of the market.
The use of hormones in sex change in fish production.
Sex of fish. Gaining much attention, however.
This method also has many limitations in terms of price and how to use.
Since most farmers have the knowledge to use.
Low testosterone, so it may be “fish” that do not match.
Needs to be ordered from abroad, causing hormones.
Loss of balance.
The Board of fisheries science. Rajamangala Institute of Technology, Trang “Uraiwan Health Department.”
I do a “study mangosteen extract from the leaves to change the gender of the fish” and ineffective.
The more attractive.
This research is important, “the mangosteen”, both fresh and dried. Were tested in each.
Concentrations that affect the proportion of sex or gender, how much. By the extraction of the tea.
To feed “fish” that can separate sex from birth. To guide the implementation of the hormone.
Natural alternative. If this works it will be useful in bringing out the sexual sterilization of fish or fish
To reduce sexual activity and affect the growth rate. It can be used.
Fish farming industry has.
For the study is divided into three stages.
Extracts were prepared. “The dried fruit” with.
Fish breeding experiment with sex and integrity.
Ready to breed. The ratio of water to water extracts.
“The fruit” is equal to 1 to 1 until the fry are 3-4 days.
Thus, the yolk is cooked at a time at 3-5.
Days later, a red mites and larvae until
In fish, as well as data collection and comparison.
Differences in sex ratio with “Chi-Square test”.
However, when fed “fish” with compost from the “leaves of fresh fruit” at different concentrations.
For 30 days showed that the extract at concentrations of 25 g has the effect of changing the sex of fish.
That is the male equivalent to 76.79%, while females accounted for 23.21% of the extract.
Concentrations of 70 g will affect the way fish are female, accounting for 76.81% of the time.
The male, representing only 23.19% for the extract at concentrations of 50 g did not differ.
The ratio between the genders. However, if the extract concentration of 100 grams will be “fish” is not.
Tolerated, and all died.
However, when the fermentation of fish with water. “The dried fruit” was not found to affect the rate.
Changing the ratio of male to male sex, and whether the concentrations of the extract, 25 g 0 g.
50 g 70 g or 100 g. The fish were fed with 25 g of the substance concentration.
Found that the gender difference is much less common in males and females 42.08% 57.92% so.
Fish fed with the extracts. “The dried fruit” in all treatments have a higher ratio of males and females.
Can not be converted into a male.
By “Uraiwan Health Department” have suggested that the outcome of the research. There should be a trial.
Concentration of the extract did not exceed 25 grams in order to find an appropriate concentrations of.
Change gender, as well as the study of “the mangosteen” to change the sex of fish and other types of economies.
The females are. And should have studied the fermentation of “fish” from a breeder.
To be effective in changing gender
The results of this project were clear that the extract “the fruit fresh” at the concentrations 25.
Grams that have the effect of changing the “fish” as much sex as possible. The good news for both the seller.
The parties will develop a beautiful breed and needs. It will be used.
Technology to alter nature. That might be a little weird. To me somehow.
