Japan gives male eels a sex change to cater to market preferences, why is there even a different market demand for the sex of fish these days?

By mentioning the eel, we all know a bit about this creature. Many people think that this creature is capable of discharging electricity, but in fact it does not. This does not prevent people from pursuing it, after all, the eel's spine is less flavorful, loved by everyone. And Japan is also very fond of eels, and their eels are basically produced in the waters of the Western Pacific.

But it didn't occur to me that on November 27th a Japanese aquaculture center published a report that caused an uproar. The farm had developed a technique for turning male eels into female eels, and they were in the process of patenting the technology. The news caused a lot of controversy when it broke, with many people saying that it turned out that there was a market demand even for the sex of the fish.

In fact, it can be seen that the demand for the sex of the animal exists in Japan, as early as the male crabs are more expensive than the female crabs. And this time it is the female eel that will be more expensive than the male eel. The main reason for this is still because female and male animals, they taste different and have different flavors. So Japan goes for the tastier ones, and again the female eel is a bit bigger and its meat is a bit tastier and more tender.

But the female eels that are farmed are very few, mostly male eels. And naturally, the Japanese breeding centers are not willing to do anything about this phenomenon, which is why they are trying to come up with a lot of techniques to solve this problem. However, there are clear regulations in Japan that prohibit the use of hormones in food fish. So the various breeding centers even racked their brains, and finally one breeding center came up with soy isoflavones, and they were successful.

Of course, they also took advantage of one of the eel's natural attributes to operate, that is, the eel is not at all sure of its sex until it grows to 30 centimeters after it is born. Soy isoflavones, on the other hand, are a type of phytoestrogen. But is a fish raised this way harmful to humans or not? Still, time will have to decide.
