Japanese eels are facing the risk of exhaustion due to over-fishing which is why Japanese companies have started importing Vietnamese catfish and making the cheaper unreal Japanese eel. Eel made from catfish is now the top-rated item at AEON supermarket. In order to be sold, it must meet quality and hygiene standards as well as packaging requirements.
