Geoduck farmers plan to sell the bivalves to China and Japan , where prices are as hefty as the clam itself. Farmed geoducks may bring even higher prices because they're uniform in size and tend to have white siphons, which Asian buyers prefer. The siphons, which taste something like octopus, are sliced for sushi. They've got a texture like a cucumber. The rest of the animal tastes akin to abalone, and can be fried or boiled.
Geoducks have a life cycle similar to that of many clams.
Adults release eggs and sperm into the water and the fertilized eggs develop into microscopic, free-floating larva that drift on the currents. After 23 to 28 days the larva grow shells and settle to the sea floor. The life cycle presents several challenges for growers. First, male geoducks look just like female geoducks. When selecting broodstock, farmers can only hope that they've got enough of both sexes.
