Species Overview
European Eel
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.
Rainbow Trout
The rainbow trout is native to cold-water tributaries of the Pacific Ocean in Asia and North America. Widely introduced worldwide, it is prized by anglers for its acrobatic leaps and beautiful coloration.
