The conservation and recovery of native trout Trout breeding in Asturian rivers has become a priority for various fishing associations and local governments. In recent weeks of June, several initiatives have focused on restocking the main riverbeds with tens of thousands of this species of fry, in order to preserve biodiversity and combat threats to their survival.

In different councils of Asturias Mass releases of trout have been carried out, such as in the municipality of Colunga, where the El Esmerillón Fishermen's Society, accompanied by the Mayor José Ángel Toyos and environmental agents of the Principality, released 15.000 brown trout fingerlings. This action, which is being repeated for the fourth consecutive year, reinforces the local commitment to the sustainable development and the protection of aquatic resources.
Promotion of fishermen's associations and institutional support
The El Esmerillón Fishermen's Society, based in Cangas de Onís, manages its own fish farm in Parres and is actively involved in the breeding and subsequent release of native trout to restore the balance of river ecosystems. The repopulations not only do they have municipal support, but also with the collaboration and supervision of environmental agents responsible for controlling and recording repopulated areas, ensuring traceability of the activity.
The releases are not exclusive to eastern Asturias. In the municipality of Quirós, the Royal Asturian River Fishing Association recently carried out a similar operation, restocking the Lindes, Ricabo, and Quirós rivers and the Bermiego stream with 35.000 fingerlings raised in its own laboratory. The initiative included the participation of the association's board of directors, a biologist from the Ministry of Rural Environment and Agricultural Policy, and rangers from the Las Ubiñas-La Mesa natural area, demonstrating the importance of collaboration between different groups for the project's success.
Environmental education and challenges for native trout
Despite efforts, there are serious threats to native trout, such as the emergence of invasive species. Fishermen warn of the growing presence of the river bogue, which competes with trout for habitat and food, hindering their regeneration in certain stretches of the Nalón River. In addition, the proliferation of hybrids such as "escayos," a mixture of carp and crucian carp, is reported, further complicating the situation.

Commitment to the environment and future prospects
Local administrations, with the support of associations, are promoting active measures to protection and restoration of riversThese actions include restocking native trout, environmental education campaigns, and cleanup of river environments. All of this contributes to improving biodiversity, strengthening the community, and promoting a sustainable rural development.
The continued efforts of fishermen, environmental groups, and government authorities reflect a strong commitment to protecting native trout and river resources. Although challenges related to invasive species and habitat pressure persist, local coordination and commitment are essential to ensuring the survival of the species and the ecological richness of Asturias.
