Species Overview

Atlantic Salmon

The Atlantic salmon is an anadromous species that migrates from the ocean to freshwater rivers to spawn. Renowned among fly fishers, it is also one of the most important farmed fish species globally.

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.
