1. Carry out assessments of oyster production in relation to primary productivity and nutrient cycles in five or six coastal areas used for oyster ongrowing and fattening in Tasmania

2. To develop predictive models of the carrying capacities of these areas

3. To utilise these models in the formation of a general model which can be applied with specific minor modifications to existing and potential intensive shellfish farms

4. To apply this general model in the day-to-day shellfish farm management
