Climate change, oceanographic variability and the artisinal fisheries in the South West Atlantic

The document outlines a project assessing how oceanographic variability, such as wind and currents, affects pink shrimp harvests in Brazil's Patos Lagoon. It highlights the interaction between environmental stressors and inadequate policy frameworks, such as fixed fishing seasons and easy credit, which exacerbate the vulnerability of artisanal fisheries.

• Pink shrimp harvests in the Patos Lagoon are driven by wind and ocean currents; landward currents caused by southwesterly winds and low river runoff lead to successful catch seasons, while large river outflows block larvae influx and decrease catches. El Niño (ENSO) may further reinforce these trends by shifting the distribution of migratory species.
• Environmental impacts are perceived as more severe when combined with poor policy decisions, specifically the use of fixed fishing seasons and easy access to credit that encourages unsustainable fleet expansion and overcapacity.
