Authorities in the Argentine provinces of Corrientes and Chaco have implemented extraordinary fishing bans on specific stretches of the Paraná River, specifically between kilometers 1109 and 1150. The measures were triggered by the detection of exceptionally large schools of fish, including dorado, which increased the risk of overfishing and vulnerability for the species.

The bans prohibit all forms of fishing, including commercial, sport, and subsistence activities. To ensure effective conservation, the regulations include a dynamic protection scheme: if the fish concentrations move outside the initially defined boundaries, the ban will follow the school to its new location. Enforcement involves continuous patrols by environmental brigades, with violators facing significant fines and disqualification from natural resource-related activities.
