From the 1st to the 4th of September 2025, the 22nd International Conference on Diseases of Fish and Shellfish, organized by the European Association of Fish Pathologists (EAFP), was held in Heraklion, Greece. Within this international context, a dedicated workshop entitled “Nodavirus in wild fish: addressing the Mediterranean grouper mortality crisis” took place on the 3rd of September. This workshop represented the first coordinated scientific initiative focused entirely on understanding the increasing mortality events associated with Betanodavirus infection in wild groupers across the Mediterranean Sea, where unprecedented mortality levels have been recorded in Spain, Italy and Greece during the past two years.
Toffan et al. (2026) studied this question.
