Species Overview
ヨーロッパウナギ
The European eel undertakes one of nature's most remarkable migrations, traveling 5,000 km from European rivers to the Sargasso Sea to spawn and die. Despite centuries of study, its breeding grounds were only recently confirmed.
Nile Tilapia
The Nile tilapia is the most widely farmed fish species in the world, cultivated in over 120 countries. Originally from Africa, it is a hardy, fast-growing mouth-brooder that thrives in a wide range of environmental conditions.
