Bizerte Lagoon is connected to the Mediterranean sea and is under strong marine influence (Photograph by Prof. Nejla Aloui-Bejaoui). 
The technique used is suspended Oyster culture ; Crassostrea gigas is attached to fiber ropes. Oysters are off-bottom and permantly suspended in nets, in deep water (4 -7m). (Photograph by Prof. Nejla Aloui-Bejaoui).

Oyster exploited in Tunisian farms is Crassostrea gigas. This species has been exploited since 1963 in Bizerte Lagoon (North Tunisia) which is until today the only site of Oyster culture in Tunisia. (Photograph by Prof. Nejla Aloui-Bejaoui).

The oyster Aquaculture started in Tunisia in the 1967, where there was import of spat from Japan in the first time then from France. Crassostrea gigas can not reproduce naturally in the Tunisian waters, so that and in order to develop this activity, there was a project of collaboration (2009-2011) between my Institute and the National Fisheries Research and Development Institute of Korea (NFRDI) and KOICA to make artificial seedling production of Crassostrea gigas. A pilot hatchery was created and we succeeded producing oyster spat. Actually, we produce spats for the benefit of 10 private farms (ongrowing) located in Bizerte Lagoon. (Dr. Chalghaf Mohamed)
