Download FAR 2013/51 An updated stock assessment for Foveaux Strait dredge oysters (Ostrea chilensis) for the 2012 fishing year

This report summarises an update of the stock assessment for Foveaux Strait dredge oysters up to 2012. The model estimates of the state of the Foveaux Strait oyster stock suggest that the exploitation rates have been low, and the stock continues to recover following a dramatic reduction in the vulnerable abundance since the recent outbreak of the Bonamia epizootic. Current estimates from the basic model suggest that spawning stock population in 2012 was about 35% (31–41%) B0.
