Dusky grouper massive die-off in a Mediterranean marine reserve

The dusky grouper Epinephelus marginatus (Lowe, 1834) is a key predator in shallow Mediterranean rocky habitats. Due to fishing pressure and slow population dynamics, dusky grouper populations are declining across their distribution range. Here we document a massive die-off of E. marginatus in the C...

Due to fishing pressure and slow population dynamics, dusky grouper populations are declining across their distribution range. Here we document a massive die-off of E. marginatus in the Columbretes Islands Marine Reserve (NW Mediterranean Sea) during the summer and early autumn of 2023.
