Section outline

    • Since larvae have weak swimming ability, they are drifted in the ocean currents along the coasts of Japan, South Korea, Taiwan, and China for approximately half a year.

      The larvae that have reached their maximum body length transform to an elongated cylindrical shape, which is the shape of the eels we all know (glass eel).

      This is called “metamorphosis,” and the eels do not eat any food during this period.

      Once they have completed metamorphosis, they recruited in the river mouth area, and their body becomes pigmented as they start eating food (elver).
