Once widespread in UK rivers, European sturgeon are now critically endangered due to river dams, pollutions and fishing. BLUE is working to restore the UK’s population of this prehistoric fish.
The IUCN considers sturgeon to be the most critically endangered group of species on the planet. However, they were once a common sight in the UK’s river and coastal ecosystems, remaining mostly unchanged for the past 200 million years. Two species are present the UK, the more widespread European sturgeon and its close cousin the Atlantic sturgeon. However, weirs and dams, pollution, exploitation and persecution have almost led to the extinction of the ‘Dinosaur Fish’.
To reverse the decline of the UK’s native sturgeon species, Blue Marine is focusing on habitat restoration (starting in the greater Severn estuary system) and has ambitions to reform current legislation for increased protection. Blue Marine hopes to raise awareness of and increase pride in this great British fish, while exploring ways under the IUCN Reintroduction Protocol to begin actively restoring sturgeon numbers in the future.

In 2020, the UK Sturgeon Alliance was formed between Blue Marine, the Zoological Society of London (ZSL), the Institute of Fisheries Management (IFM), the Severn Rivers Trust and Nature at Work. The Alliance is keeping records of all native sturgeon captures throughout history and hopes to one day see this incredible species return to UK waters.

According to the IUCN, sturgeon are the most critically endangered group of species on the planet.
By working together, we can turn the tide on overfishing and the destruction of biodiversity. By supporting Blue Marine, you can help to create marine reserves around the world.
