The two photos show two methods of oyster farming that are namely cement and long line methods. The  3-4 cm; (3-4 months age)  Crassostrea belcheri  oysters are either stick on a cement  pole or stick on a rope using cement and then after, they are placed in the chosen rearing ground in natural waters. The harvesting takes place after 7-8 months whereas the average size reaches about 10-15 cm. Restaurants represent the principal market for the harvested oysters while small quantities are marketed in local fish markets..

Note: We decided not to watermark the photos in order not to upset its clarity. However, we trust you will notify us if you wish to use a picture or more. This is expected and will be appreciated.
