Pacific oysters were introduced from Japan in the early 1900’s and are now widely farmed in estuaries along the US West coast.

With a few exceptions, Pacific oysters are mostly cultured in intertidal areas of US west coast estuaries where they are either spread directly on the sediment or suspended above bottom on long-lines or in bags or cages.

Pacific Shellfish Research Unit scientists are currently implementing a new breeding program using genomic selection to develop disease resistant/tolerant strains.

Pacific Shellfish Research Unit scientists are investigating the interaction between oysters and eelgrass. Both eelgrass and oysters provide estuarine habitat for crab and fish.

Burrowing shrimp dig extensive burrows and cause oysters to be buried in the sediment.  Scientists continue to monitor shrimp populations and  search for effective and sustainable control measures for these shrimp.
