While uncertainty exists in levels of future recruitment and continued B. exitiosa related mortality, projections from the Foveaux Strait oyster stock assessment model indicate that current catch limits are unlikely to have any significant impact on future stock levels.

Patches of commercial densities of oysters within the OYS 7 fishery are largely restricted to Tasman Bay. The stock is likely to be biologically isolated from the Foveaux Strait population on the basis of geographical distance. The population in OYS 7 and OYS 7C are very likely genetically linked because of gene flow between these different stocks.

Oysters in OYS 7C (Cloudy Bay/Clifford Bay) form discrete patches on a predominantly sandy substrate. The stock is likely to be biologically isolated from the Foveaux Strait population on the basis of geographical distance. The populations in OYS 7 and OYS 7C are very likely genetically linked because they share boundaries.
