Species Overview

Brown Trout

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.

Zebra Danio

The zebrafish is a small cyprinid native to South Asia's freshwater streams. Its distinctive blue-and-gold horizontal stripes and hardy nature make it a popular aquarium fish. It is also the most widely used vertebrate model organism in genetic research.
