Growth rates and fitness indicators of offshore cultivated oysters (Pacific Oyster Crassostrea gigas, European Oyster Ostrea edulis)
Within this project the suitability of oysters as candidate species in offshore aquaculture shall be valuated. Therefore, two different species of oysters (edible oyster = native European Oyster Ostrea edulis and Pacific Oyster Crassostrea gigas) are cultivated in offshore areas.
To make a statement on the adequacy of offshore oyster cultivation the following parameters are determined at regular intervals:
- growth rates (size, weight)
- condition index (meat/shell ratio)
- fitness (proteins, enzymes, lipids, glycogen, RNA/DNA ratio)
- health (accumulation of toxins)
and compared to oysters originating from an inshore cultivation or wild individuals.
