Species Overview
Pirarucu
The arapaima is one of the largest freshwater fish in the world, reaching up to 4.5 meters. An obligate air-breather, it must surface every 10-20 minutes to gulp air. Its tongue is bony and used to crush prey against the roof of its mouth.
Truite de mer
The brown trout is native to European rivers and has been introduced worldwide. Renowned for its wariness and intelligence, it is the ultimate quarry for fly fishers. Larger specimens become nocturnal, feeding primarily on smaller fish.
