Species Overview

Atlantic Cod

The Atlantic cod is one of the most historically important commercial fish species. Its mild, flaky white flesh has been a staple food in Europe for centuries. Overfishing caused the collapse of the Grand Banks fishery in 1992.

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.
