Guidelines for safe handling and release

We have developed a comprehensive handling and release guide for sharks and rays—created to support both fishermen and scientists in improving survival. A comprehensive guide with practical advice and showcase from rehabilitation clinics and in-vitro incubation. 

Prepared under the framework of UNEP MAP Barcelona Convention (SPA/RAC), Italian Ministry of Environment and Energy Security (MASE) and GEF.
