Japan performs sex change on male eels to cater to market preferences. How does it do that?

They added some substances such as soy isoflavones that have similar ingredients to estrogen into the bait. As long as the male eels eat this kind of feed for a long time, the estrogen in the male eels' bodies will become more and more over time, and they will eventually turn from male eels into female eels.

Recently, Kyodo News of Japan released a report that attracted the attention of netizens. It was that in an aquaculture fiber-aquaculture test site in Aichi Prefecture, Japan, they conducted a special experiment, which was to prepare to turn male farmed eels into female eels. This technology was developed after many years of research, and they are also applying for some patents for this technology to protect this self-cultivation technology. The main reason why they want to conduct this experiment locally is that the yield of eels caught in some wild sea areas has been getting lower and lower, and the number of eels near the Sea of ​​Japan is also decreasing year by year. At the same time, the demand for eels in the Japanese market has not decreased, but has been increasing year by year.

In particular, the demand for female eels is increasing, so relevant Japanese agencies came up with the idea and planned to turn some male eels in the farms into female eels through some technical operations. However, some Japanese laws have clearly stipulated that the use of estrogen for edible fish is not allowed, but there are no restrictions on soy isoflavones, so local experimental institutions began to plan to feed soy isoflavones to male eels. The basic composition of this material is very similar to that of estrogen, and it can also achieve the same effect.

However, some netizens expressed their concerns after seeing such news, thinking that they dare not eat such eels, and they are worried that such farmed eels may have a certain impact on their bodies, and they cannot get over this psychological barrier. According to this experimental combination and split field, after a period of experiment, it was found that if these farmed eels are fed with soy isoflavones, basically after a period of feeding, more than 90% of the male eels in the farm will become female.

Some institutions in Japan are preparing to use some technical operations on male eels in farms to turn them into female eels. Many netizens saw this news and said that they would never eat these eels again because they are worried that it will cause bad danger to their bodies.

According to a report by Kyodo News on the 27th, the Aichi Prefecture Fisheries Experiment Station in Japan recently announced that the test station has developed a technology that can turn male farmed eels into females, that is, mixing "soy isoflavones", an ingredient similar to estrogen, into the bait, and is applying for a patent for this technology. In recent years, the catch of eels has decreased and the production has decreased, so the market demand for female eels has become greater. Although Japan's "Pharmaceuticals and Medical Devices Law" prohibits the sale of estrogen to edible fish, it is said that there is no problem with adding soy isoflavones to fish.

In order to cater to market preferences, Japan has changed the sex of male eels. Japan has added a lot of soy isoflavones to these baits, and then fed these male eels for a long time. After a long time, the estrogen in their bodies has increased, and then they have become female eels.

They will gradually add orange and soy isoflavones to the bait, which has the same ingredients as estrogen. Over time, if the male eels often eat this bait, they will slowly turn into female eels.

What is the market prospect of eel farming and how to increase sales?

The eel market is large and has good economic benefits

Eel is a high-end economic fish species with high economic value. The meat of eel is very tender, delicious, rich in fat and protein, and has very high nutritional value. At present, eels in my country are basically cultivated artificially. Eel is the largest export aquatic product in my country, bringing 6-8 US dollars in foreign exchange income to the country every year. The main consumption place of eels in the world is Japan, and 90% of my country's eel products are sold to Japan. Due to the good economic benefits of eel farming, my country's eel farming industry has developed rapidly in recent years.

Domestic sales are low

Compared with the export volume, the sales volume of eels in my country is relatively small, only 40,000 to 50,000 tons per year, and the consumption form is single, basically live fish sales. In addition to live eels, the exported eels also include a large number of roasted eels. There are many roasted eel companies in China, but their production mainly depends on the demand of the foreign market. If there is no foreign order, the roasted eel factory is basically in a state of suspension. Therefore, it greatly restricts the development of the domestic eel industry. So why don't domestic roasted eel companies produce roasted eels for the domestic market?

High domestic risk

The domestic problem is that some grilled eel factories are afraid to take risks, mainly because our seasonings have not yet passed the test. Basically, the seasonings and soy sauces exported from Japan are imported from Japan. They are imported from Japan and are formulated according to Japanese tastes. There is still a blank in China. It should be said that China is a huge potential eel consumption market, but many companies are not aware of this and only focus on the international market, so they are caught off guard when eel exports are blocked.

Ways to increase sales

I think we should strengthen the research on condiments, because the tastes of people in the north and south of China are very different. Some people like spicy food, some like sweet food, and some like sour food. If we develop grilled eels with different flavors, the market will be opened up. Experts suggest that if the eel farming business wants to develop, it is necessary to improve the quality of eels, expand exports, increase the development of the domestic eel consumer market, do a good job in deep processing of eels, and produce eel products suitable for domestic consumers. Expand the domestic market.

Eels like to live in clean, unpolluted waters. They are the purest aquatic creatures in the world. In many Japanese restaurants, eels have always been a main dish. Due to the tender and smooth taste of eels, they are often seen on people's tables. However, eels are a marine fish and have not been widely cultivated artificially, so the prospects for cultivation are still relatively broad. To increase sales, we must first increase domestic market demand and popularize the benefits of eels.

The prospects of the eel farming market are still very good. I think farming this is a good idea.

The breeding prospect is very good. Eels have two main value areas: food and medicine. Artificial eels are cultivated in Zhengsui ponds. This warm-water fish has high nutritional value. Now the intensity and scale of artificial breeding are getting bigger and bigger. In order to meet all market demands, more farmers have joined eel farming.
