Seed from Northern and Southern (hereafter called local) hatcheries was procured in May 2000. Oysters delivered by the Northern hatchery were on time and of the desired size ~3mm). Seed from the local hatchery, however, arrived several days later and were too small to go into field nursery containers and were subsequently held in upwellers and then transferred to the field nursery gear. Figure 1 shows growth as measured by mean shell height (mm) for both strains. Note that the local seed took N20 days longer to reach grow-out size (indicated by first sieve).
