Species Overview

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.

Discus

The discus is often called the 'King of the Aquarium' for its disc-shaped body and stunning color patterns. Native to the Amazon floodplains, it requires warm, soft, acidic water and feeds its fry with a mucus secretion from its skin.
