Marine aquaculture is a success story in Greece. Starting in the early 1980s, the first hatcheries supplied the first fingerlings for on-growing in cage farms. Cage farming technology was known from the salmon industry and easily adopted in the Mediterranean conditions. As the European Union (EU) imports of fishery products are much higher than its exports, aquaculture was always in the priorities of the EU strategy. Therefore, major EU funding programs and a few entrepreneurial individuals that have undertaken the challenge and the risks has led to a rapid increase in production and Greece became, and still is, the largest producer of sea bass (Dicentrarchus labrax) and sea bream (Sparus aurata) in the world. From 100 tons of ready product and 12 fish farms in operation in 1985, in just two decades the production had been increased at 1000% and fish farms exceeded 320. Greece has reached a pick in 2008 by producing more than 450 million fingerlings and 120.000 tones, but this production has reduced in order to restore satisfactory prices.
