Samenvatting

The cultivation of oysters is one of the oldest forms of aquaculture and accounts for more than 50% of the global seafood supply. With a growing world population, the demand will most likely increase. New and improved techniques will be necessary to keep up with the rising demands and threats that surround the cultivation of oysters. Oysters have been cultivated in the Netherlands since the mid19th century using on-bottom techniques. Worldwide another technique is more regularly and successfully used, namely the off-bottom technique which makes sure the oysters are suspended in the water column. However, this technique is hardly being used in the Netherlands.
