Project Description
Recovery of derelict fishing gear and ghost nets from Tunisia's Gulf of Gabès — a Mediterranean biodiversity hotspot. Combines vessel-based net retrieval, side-scan sonar surveys, and benthic habitat restoration. Co-benefits include reef recovery and reduced cetacean entanglement.
