The dusky grouper (Epinephelus marginatus Lowe, 1834) is a fish belonging to the family Serranidae.

One of the largest migratory fish that divers may encounter in the Mediterranean and has been disappeared for many decades couse of spearfishing. For this reason it was essentially vanished from our shores as a result of overfishing. It a hermaphrodite species that changes sex during growth. The underwater fishing has on it a particularly detrimental effect, because the prey most desirable are the large specimens, which, in this species, are almost always male: the effect has been to make the reproduction extremely difficult.

In recent years things have improved and small specimens of groupers have reappeared near the rocky shores even in a few meters of water as we show in this short video.
