1. To establish a functional relationship between stocking density, individual growth rate and yield for Sydney rock and Pacific oysters in an estuarine embayment in the Port Stephens estuary.
2. To generalise this relationship for relevance to other habitats by determining the interactions between available food, the feeding physiology and the growth of these oysters.
3. To use these formal relationships to demonstrate the optimal stocking densities for oyster cultivation in a variety of different environmental conditions.
4. To investigate the influence that feral oysters have upon such optimal density estimates.
5. To relate stocking density to the quality of the marketed oysters and investigate possible economic implications.
