Many diners who like Japanese food know that there is a very popular eel rice in Japanese food. Although the price of eel is not cheap, it does not affect its sales. However, the output of Japanese eel has been declining in recent years, so the eel breeding market needs more female eels to increase the output. In order to achieve this goal, Aichi Fisheries Experimental Field in Japan began to carry out technical research and development for this purpose, trying to improve the decline of output through technology.
The principle of this technology is actually to change the sex of eels by feeding them. Soybean isoflavone? . ? Soybean isoflavone? Also known as? Phytoestrogen? , a secondary metabolite contained in soybean, is extracted from soybean. This component is similar to estrogen in structure. Because eel is different from other aquatic products, its sex is not formed at birth. The sex of newborn eel fry is uncertain, and it needs to be cultivated to reach more than 30 cm in length to form sex. So, eel fry have been fed since birth? Soybean isoflavone? Can you ensure feeding? Soybean isoflavone? Our little eel will grow into a female eel.
Japan Aichi fishery experimental field claims to rely on feeding love? Soybean isoflavone? The grown-up Monopterus albus is technically restricted to be a female Monopterus albus, but it will not cause any other harm to Monopterus albus. In other words, it will not indirectly cause food safety problems, and humans can safely eat eels fed by this technology.
