Marine fish farming is the most important type of aquaculture production in Greece with over 30 years of experience. Marine aquaculture experienced rapid growth in Greece the 1980s using floating cages. In 1985 there were 12 farms licensed, producing annually 100 tons. Three decades later the production had increased by 1000%, with more than 300 farms producing more than 100,000 tons. Currently there are 63 companies operating 366 farms throughout Greece. The majority of those companies are family owned businesses and small and medium enterprises. However, there are a few large enterprises that are vertically integrated companies also producing juveniles and feed.

In Greece two species are mainly farmed, namely sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax) while at a much smaller scale some other Mediterranean species are farmed such us Meagre (Argyrosomus regius), Sharpsnout seabream (Diplodus puntazzo), Red porgy (Pagrus pagrus), Turbot, Dentex and Red Seabream.

In 2015, 110,000 tons of sea bream and sea bass were produced. These two species account for 98% of the harvest volume, while all the other Mediterranean species accounted for 2%. In 2015 Greece supplied 61% of the sea bass and sea bream sold in the EU and 31% worldwide.

The most recent and complete statistical data on Mediterranean fish farming (sea bream and sea bass) are from 2015 and provided by the FEAP, FGM and Kontali.
