摘要：

The relationship between larval setting order and subsequent spat growth in the American oyster was analyzed. Four separate full-sib families were examined. In all cases, spat that metamorphosed during the first 3 days of the setting period were significantly (P < 0.05) larger at 29 weeks post-setting than spat that metamorphosed later during the setting period. Data from one family, measured at two different time intervals post-setting, indicate that differences in size among the spat become more pronounced as the oysters get older. Hatchery selection of larvae that set earliest should, therefore, produce faster growing juvenile oysters. © 1979.
