Unexpectedly,165438/kloc-0 published a report in a feeding center in Japan on October 27th, which caused an uproar. The farm has developed a technology that can turn male eels into female eels, and they are applying for a patent for this technology. After the news came out, it caused great controversy. Many people say that even the sex of fish has a market demand.
In fact, we can see that Japan has requirements for animals. As early as before, the price of male crabs was higher than that of female crabs. This time, female eels will be more expensive than male eels. The main reason is that female animals and male animals have different tastes and tastes. So Japan will pursue better food. Similarly, the female eel is bigger and the meat is more delicious and tender.
But there are few female eels, and most of them are male eels. However, Japanese breeding centers naturally don't want this phenomenon, so they will think of many technologies to solve this problem. However, there are clear regulations in Japan that prohibit the use of hormones in edible fish. So all the breeding centers racked their brains, and the last breeding center came up with soybean isoflavone, and they also succeeded.
Of course, they also use a natural property of eels to operate, that is, after the eel is born, the sex is not determined at all, and it is not determined until it grows to 30 cm. Soybean isoflavone is a phytoestrogen. But is the fish raised in this way harmful to human beings? It still depends on time to decide.
