Aquaculture of triploid Crassostrea virginica in the Chesapeake Bay, USA is popular with the majority of growers raising mostly triploids. This choice stems from improved growth and survival relative to diploids. Triploids are made commercially by crossing tetraploid males and diploid females, thus either or both parent could influence the performance of the triploid. We examined the influence of the female (diploid) parent in an experiment comparing nine diploid (2n x 2n) and nine triploid (4n x 2n) crosses across three environments.

Triploid eastern oysters (Crassostrea virginica) are the cornerstone of oyster culture in Virginia, comprising 80% of cultured oysters in 2009. Triploids are produced predominantly by tetraploid x diploid mating. While these animals are pivotal to triploid production, there is little documentation of their characters, including larval culture of tetraploid crosses, relative to that of diploid and triploid C. virginica. To examine variation in larval traits of tetraploid C. virginica four groups of five pair-mated families each were produced from four tetraploid stocks.
