2.1. Oysters, processing and storage
Pacific oysters were harvested from a commercial oyster farm in the Coffin Bay harvesting region (−34° 33′ S, 135° 21′ E) in South Australia on 30th May 2012. Oysters were of a consistent size grade (mean shell length 6.6 cm (sd = 0.26)). The live oysters were packed in Styrofoam packaging and shipped overnight by refrigerated road transport (∼8 °C) as per standard industry practice for Pacific oysters. Oysters were processed immediately upon receipt. Sydney rock oysters were harvested from a commercial oyster farm in the Camden Haven harvesting region (−31° 39′ S, 159° 42′ E) in New South Wales, Australia on 19th June 2012. Oysters were of a consistent size grade (mean shell length 6.8 cm (sd = 0.53)). The live oysters were packed in Styrofoam packaging and shipped by road transport (∼12 °C for 48 h). Once received, oysters were stored overnight at 10 °C (as per standard industry practice for Sydney rock oysters) before processing.
