Abstract

Nodaviruses affect a large number of fish species, wild and farmed. In the wild it has been isolated in various species, but it had never been associated with clinical processes on the coast of Murcia. In autumn 2017, several specimens of groupers (Epinephelus marginatus and E. costae) were detected in the Cabo de Palos Reserve with clinical symptoms compatible with nodavirus. The infection by nodavirus was confirmed by real time RT-PCR and its subsequent genotyping (RGNNV type). This finding constitutes the first regional evidence of clinical infection by nodavirus in wild fish, with the added relevance that the affected specie, the grouper, is the emblematic specie of the Cabo de Palos Marine Reserve.
