Description and trends of the marine aquaculture sector of Greece 1985-1998

摘要

Mediterranean aquaculture production is characterized by the dominance of two species, European sea bass (Dicentrarchus labrax) and gilthead sea bream (Sparus aurata), which represent 48 percent and 50 percent of total production and about 10 otherspecies, all of For sea bass and sea bream, the production cycles for which are totally controlled at all life stages, so the majority of fry are produced in hatcheries. For the other species, where the biological cycle is not yet totally controlled, fryare obtained from wild fishing, followed by adaptation to captivity. The extended length and complex morphology of the Greek coastline, forming a large number of sheltered areas and gulfs, as well as the existence of numerous islands and the mild climate, provide the ideal conditions for all forms of mariculture. The majority of culturists use intensive rearing methods in floating cages or in concrete raceways. However, semi-intensive techniques in earthen ponds with supplemented feeding as well as extensive forms in lagoons and earthen ponds can be found. Sea bream, sea bass and mullet are all grown in extensive, semi-intensive and intensive systems, though the use of intensive systems for mullet is in the early stages of development.
