Sharks are among the most threatened marine species in the Mediterranean, with populations declining rapidly due to overfishing, bycatch, and habitat degradation. In Tunisia, a leading producer of elasmobranchs in the region, there is a critical lack of data on the distribution, behaviour, and conservation status of shark species, particularly the great white shark (Carcharodon carcharias) and the shortfin mako shark (Isurus oxyrinchus). Both species are classified as critically endangered by the IUCN, yet their ecological roles and population dynamics remain poorly understood. This project aims to address these gaps by conducting comprehensive scientific analyses, including morphometric and genetic studies, to assess the presence and distribution of these sharks in Tunisian waters. The project will also identify critical habitats and work with local stakeholders to promote sustainable fishing practices and raise awareness about the importance of shark conservation.
The project focuses on several key objectives:
- Conducting morphometric and genetic analyses to study the population structure, genetic diversity, and distribution patterns of great white and shortfin mako sharks.
- Identifying and mapping critical habitats for these species, particularly in areas with high elasmobranch landings, such as the Gulf of Hammamet and Monastir Bay.
- Engaging local fishermen, fisheries committees, and NGOs to collect data on shark interactions with fishing gear and promote sustainable fishing practices.
- Organising capacity-building workshops for fishing guards, port reporters, and fishers to improve species identification, data collection, and conservation practices.
- Raising awareness among local communities and stakeholders about the ecological importance of sharks through educational campaigns and media engagement.
By combining scientific research with community engagement, this project aims to contribute to the long-term conservation of these vulnerable shark species in Tunisia, while fostering sustainable marine resource management practices. The findings will be shared through scientific publications, conferences, and technical reports, ensuring that the data informs both local and international conservation efforts.
