Adverse weather and high costs mark a year of decline for fish farming in Rio Grande do Sul.

The state of Rio Grande do Sul registered a decrease in farmed fish production in 2025. The volume was 24,300 tons, a drop of 0.41% compared to the 24,400 tons produced in 2024. Even so, the result represents an increase of 8.95% compared to 2023, when 22,400 tons were produced.

According to data from the Brazilian Aquaculture Yearbook PeixeBR 2026, last year's performance was impacted by a number of factors. Extreme weather events, with droughts and floods at different times, directly affected the activity in several regions of the state. In addition, the increase in production costs — especially for feed and energy — put pressure on producers.

Fish farming remains concentrated on smallholdings, with production primarily geared towards the local market. Tilapia continues to be the most cultivated species, but the state also maintains production of native species.

Despite the challenges, the sector remains relevant to the rural economy of Rio Grande do Sul and shows potential for growth, especially with the adoption of technologies and improvements in production management.
