Virus suspected in fish die-offs along island shores

Alarming numbers of dead groupers and other fish have been found along the southern coast of Crete, Andros, Tinos and Syros since early September.

Investigations led by the Hellenic Center for Marine Research (HCMR) point to a viral culprit, Betanodavirus, which is known to affect species like dusky groupers (Epinephelus marginatus) but is harmless to humans.
