| Introduction : Growth and survival are the life-history traits of the most interest for oyster production since they determine biomass output (growth x survival). This study aimed to investigate whether there is genetic basis for growth, survival and their plasticity to know if a selection program is conceivable for these traits. Material and Methods : Nested half-sibs mating design was used to produce families of oysters: 5 males were each mated to three females producing 5 half-sibs families, each containing 3 full-sib families. At 15 months of age (May 1999), each full-sibs family was randomly split into five groups which were given different treatments. Two groups were placed in a constant environment: one with low food resources and another with high... |
