This measure was intended to boost tourism in the cordillera region. The regulation required a “mandatory return of all captured specimens” to ensure sustainable resource management. By late October, fishing regulations expanded in other regions. In Tierra del Fuego, Argentina, the sports fishing season was scheduled to run from October 30, 2026, to May 2, 2027, featuring specific permit fees and a mandatory catch-and-release policy starting in March 2027.

Concurrently, Chile declared a preventive emergency due to the threat of Harmful Algal Blooms (red tide) across 15 coastal regions, effective from November 1, 2026, to June 30, 2027.
