The pearl oysters, Pinctada maxima and P margaritifera, respond in different ways to culture in dissimilar environments
Growth, Condition Index (CI) and survival of the pearl oysters, Pinctada maxima and R margaritifera, were measured in three size groups of oysters over 14 months at two dissimilar environments in the Great Barrier Reef lagoon. These were the Australian Institute of Marine Science (AIMS) in a mainlan...
