Hatchery production of Sydney Rock Oysters (SROs, Saccostrea glomerata) is a costly and high risk activity for the breeding program and industry exacerbated by factors such as: reliance on hatchery conditioning, low fertilisation success using strip-spawned gametes, extended larval rearing period...
This report outlines the results of investigations into the feasibility of cost effectively marking or labelling individual oysters and other shellfish for product differentiation and to facilitate rapid and efficient recall of product in the event of a potential public health incident.
A number of...
