La Escala de Salmones de San Tirso de Abres es una infraestructura ecológica situada en la Vía Verde del Ferrocarril del Eo, en el concejo de San Tirso de Abres, Asturias. Esta estructura permite a los salmones superar las barreras físicas impuestas por las presas en su ruta migratoria hacia las zonas altas del río Eo, donde se reproducen. Consiste en una serie de escalones interconectados que facilitan el ascenso de los peces, contribuyendo a la conservación de la biodiversidad fluvial.
Además de su función ecológica, la escala de salmones es un punto de interés en la Vía Verde del Eo, una ruta de senderismo y cicloturismo que sigue el trazado de un antiguo ferrocarril minero. A lo largo de este recorrido, los visitantes pueden disfrutar de paisajes naturales y observar la fauna local, como nutrias y aves acuáticas. La escala de salmones destaca como ejemplo de ingeniería ambiental aplicada a la conservación de especies migratorias en el río Eo.
There are remains in the Oscos region that tell us that mining was an activity that was developed in the area since prehistoric times. Before the conquest of the Romans, the inhabitants of this region were already looking for gold nuggets in the river placers. But it was after the arrival of the Romans that this industry was boosted. In the Flavian period, at the beginning of the first century A.D., a first golden age was experienced. The castros (fortified settlements) resurged as a result of the exploitations and the landscape was dotted with small industries of which there are still remains such as: forges, function furnaces and samples of the technology that was used for the exploitation of the deposit.
The town of Vegadeo has the peculiarity of being crossed by two rivers: the Monjardín and the Suarón, which have twelve bridges that cross them (six each). Taking advantage of this circumstance, the idea was that visitors to Vegadeo could get to know the town center by crossing these bridges, and enriching the visit with a sculpture on each of them.
Through different media (audiovisual, photographic and computer) we can learn about the Eo River, the different species that inhabit it or the relationship of man with the river; how humans have taken advantage of the wealth offered by its waters and, above all, the importance that fishing has had in the area.
