Greek aquaculture boomed over the last two decades, mainly due to massive production increases in sea bass and sea bream. Technological developments, favourable natural conditions and available national and EU funds for production infrastructure investments drove this intensification in production. The paper provides an extensive overview of the regulatory framework of the aquaculture sector, including legislation for licences, environmental protection, coastal zone development and the regulation of competition over land and water resources. It also specifies the role that public funding played in terms of increasing production volumes and product promotion.
