Pacific oyster outplants and benthic surveys on intertidal aquaculture beds (Washington state, USA)
Hypothesis: Pacific oyster (Magallana = Crassostrea gigas) performance and yield differ between ground culture and off-bottom culture methods and depending on the level of co-occurring eelgrass (Zostera marina).Benthic surveys were carried out on aquaculture beds at 10 sites around Washington state,...

Relative to ground culture, off-bottom culture produced higher densities of oysters per footprint of area and/or increased yield due to shorter crop cycles.
