Species Overview

Saumon de l'Atlantique

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 common pleco is a large armored catfish native to South America. Often purchased as an algae eater, it can outgrow most home aquariums. Its sucker-like mouth allows it to rasp algae from surfaces and anchor itself in fast-flowing currents.
