Costs of induced defenses dissipate by maturity for diploid and triploid oysters

These data include oyster morphological characteristics of diploid and triploid oysters cultured as "single seed". Oysters were nursed with and without predator cues (caged blue crabs, controls of no cues) for one month before being raised at Auburn University's experimental farm in Grand Bay AL following standard aquaculture procedures. Subsets of oysters were assessed periodically until maturity for shell strength, shell size, shell dry weight and soft tissue dry weight using a Kistler force sensor and drying oven. Oyster somatic tissue mass, reproductive tissue mass, and gonadosomatic index were also measured at maturity and shortly prior to maturity.
