What the guide says about the closed season

🚫 Annual closed season
Every year MADES sets by resolution a closed season for sport and commercial fishing during spawning; the only exemption is subsistence fishing by riverside fishermen holding a commercial licence, from the bank and without a boat. The 2026/27 one is Res. MADES 511/2026, of October 22, 2026: it starts at 00:00 on November 2, 2026 across the country. In waters shared with Argentina: until December 21 (50 days; in 2024/25 and 2025/26 it was until the 20th, in 2023/24 until the 15th). Inland rivers, streams and lagoons follow that same date. In waters shared with Brazil (the Paraguay River from the Río Negro to the Apa, the Apa River and the Paraná from Saltos del Guairá to the Yguazú): until January 31 (2027, the same date as in the last five closed seasons). During the closed season it is also banned to sell or move live bait, and to take or sell tareyí (tararira, wolf fish) and mbusu (swamp eel). Fishing during the closed season: fine of 1 to 20,000 minimum daily wages depending on severity (Decree 1837/2019), today up to Gs. 2,342 million.
