For 10 years SRO have been bred in various hatcheries in NSW. They have all encountered some difficulties and supplies of juvenile spat has been inconsistent. Pacific Oysters (C.  gigas) and Flat Oysters ( O.angasi) are easier to breed intensively.

The advantage with Hatchery bred stock is that over time it has been bred for disease resistance ( the two major diseases affecting SRO’s are Q X Disease and Winter Mortality) and the stock has been selected for fast growth and shape.

We have both types of SRO as some markets or customers have different preferences. In any one season we try to purchase or breed ourselves 1 million SRO and 300 -500,000 flat oysters. This does not include our wild caught stock. Hatchery oysters are integral to our future and I also feel the whole NSW Oyster Industry. The development of successful  commercial hatcheries underpins  modern and progressive oyster industries, as is the case in USA, Canada, France, UK ,Japan and Korea.
