Abstract
Organic aquaculture has recently attracted attention from both researchers and industry. Organically produced aquatic products are increasingly available to consumers and, in particular, sea bass and sea bream from certified farms in Greece have been exported and also channelled to large retail markets in Greece since 2008. The current paper briefly reviews issues pertaining to global organic aquaculture and national organic and conventional aquaculture production with a special focus on organic sea bass and sea bream production. Finally, future prospects and challenges are discussed in a wider context with regard to environmental sustainability, markets and further development of organic aquaculture.
