Through stimulating research and sound science, the Atlantic Salmon Trust is the foremost evidence-based salmon conservation charity in the UK. Fighting to halt the dramatic decline in wild Atlantic salmon stocks, the Trust is on a mission to protect this iconic species and safeguard their future. The wild salmon population is in drastic decline. In the mid 1980s, there were between 8 and 10 million salmon leaping around the Atlantic. That number has now plummeted to between 2 and 3 million, revealing a dramatic population free-fall that shows no signs of levelling out. So much so, that the wild Atlantic salmon could become an endangered species in 10 yearsβ time, disappearing from our seas and rivers altogether in just 20 or 30 years. This is a warning we simply cannot ignore. The Atlantic Salmon Trust exists solely for the protection of wild salmon and sea trout. It is our aim to create a positive future for these at-risk species; using scientific research to understand their decline, and using the generous donations from our supporters to put evidence-based solutions into practice. Wild Atlantic salmon are an iconic species with a remarkable history. They are uniquely placed to inform us of the quality of our waters, and form an incredibly important part of the ecosystem of our rivers. We cannot afford to lose themβand thatβs why everything we do at the Trust is designed to put #WildSalmonFirst
