12 What did the study explore? How has marine aquaculture in Tunisia evolved spatially and over time?

Using historical satellite imagery, Sentinel-2 data and administrative records, the study mapped how marine aquaculture in Tunisia has evolved spatially and over time between 2004 and 2026.

Key findings:

  • 70 authorized aquaculture sites were mapped and analyzed.
  • More than half of the concessions remained active, while a significant share did not achieve sustained production.
  • Finfish farming expanded, with a shift toward larger cages and more standardized and complex farm configurations.
  • A gradual movement toward deeper offshore waters was observed.
  • The study distinguishes between authorized sites and sites with visible aquaculture infrastructure, providing a clearer picture of actual spatial occupation.

Why does it matter?
By combining satellite imagery and geospatial analysis, this study provides a valuable baseline for Marine Spatial Planning, Integrated Coastal Zone Management and evidence-based coastal governance in Tunisia.
