European Sea Sturgeon

Acipenser sturio

The European Sea Sturgeon, scientifically known as Acipenser sturio, is a critically endangered species of sturgeon found primarily in the coastal waters and rivers of Western Europe. Recognized for its prehistoric appearance, this majestic fish can grow up to 3.5 meters in length and weigh as much as 400 kilograms. Its body is elongated with an armor of bony scutes lining its sides and back, giving it a unique rugged look. The coloration varies from blue-gray to olive-brown on its dorsal side, with a lighter belly, providing excellent camouflage in its natural habitat.

European Sea Sturgeons are anadromous, migrating from marine environments to freshwater rivers for spawning. Historically widespread, their populations have dwindled due to overfishing, habitat loss, and pollution, leading to their critical status today. They are known for their longevity, with lifespans that can exceed 100 years, and their late maturity, making population recovery efforts challenging. Conservation initiatives are underway to protect habitats and reduce human impact, fostering hopes for this ancient species' survival and potential restoration across its former range.
