Sturgeon

About

How sturgeon lives

Sturgeons are ancient large fish that migrate through rivers and coastal waters to reproduce. Some sturgeon lineages have changed relatively little for more than 100 million years. River species are shaped by changing water levels, flowing currents, and narrow migration paths.

Conservation

Status and habitat pressure

Critically threatened species often survive in fragmented populations, making every breeding group important. Protecting sturgeon also depends on keeping rivers, coast habitats healthy and connected.

Critically threatened species often have little room for delay because every remaining population matters.

Things to notice

• Some sturgeon lineages have changed relatively little for more than 100 million years.
• Fish body shapes often reflect how they move, feed, and avoid predators in different waters.
• River species are shaped by changing water levels, flowing currents, and narrow migration paths.
• Critically threatened species often survive in fragmented populations, making every breeding group important.
