Production and marketing trends of the cultured Mediterranean mussel Mytilus galloprovincialis Lamarck 1819, in Greece

Bivalve production in Greece pertains to a vast extent of mussel farming and a few other species of fishery products. Mussel farming in Greece covers 375.5 ha primarily located in the northern part of the country. About 523 farms have been licensed since 1976, of which 218 are using the single long-line floating technique for a nominal production capacity of about 100 t/ha and a farming area of 1-2 ha on average. The total annual production (gross pergolari weight) increased to 36,000 t in 2008. Currently, there is a trend for further expansion by licensing new farming sites. Eighty percent of the farmed mussels are exported fresh and intact, primarily to Italy. One major problem seems to be the increasing number of harmful algal bloom incidents during the past decade. The future of the industry depends on the industrialization of production methods and the development of scale to suppress the production cost. Support of product branding and development of a quality scheme would further strengthen the sector
