| Summary: | An assessment was made of three Pacific oyster ( Crassostrea gig as) growing areas in southern Tasmania (Pitt Water, Pipeclay Lagoon and Little Swanport) with respect to water quality parameters, oyster growth and hydrodynamic characteristics. This was done in an order to explain differences in reported oyster growth rates and hence address the issue of shellfish productivity in each area. Water samples were collected monthly for 13 months from several sites along the length of each area from a marine site to the. upper reaches of the estuary, or coastal embayment. These were analysed for chlorophyll a, nutrients (NOX, P04-P and Si04-Si), and seston quality and quantity (i.e. total particulate matter (TPM) and particulate organic and inorganic matter (POM & PIM)). Temperature, salinity and secchi disk depths were also recorded. Oyster growth and condition were assessed from studies conducted over three consecutive periods at two sites within each area. Hydrodynamic characteristics were calculated from ... |
