Geoduck clam farming is growing steadily year-by-year, as it is an extremely profitable enterprise. When they are harvested, the net amount of nitrate in the water is greatly reduced. The clams eat the excess algae and actually store some of this excess nitrate in their bodies. Micro algae grow when there is extra nitrate in the water, and the increase in pollution in our modern society has led to an increase in nitrogen in our waters. In fact, the farming of geoduck clams is actually beneficial to the aquatic environment. This technique does no harm to the environment around the fishery. The farmers spray the area with high-pressure water hoses that liquefy the sediment where the clams are buried. Harvesting techniques are very interesting. The clams are harvested ever four to six years. These pipes prevent predators from reaching the young clams. Geoduck farmers employ special pipes pushed into the sediment in which to raise the clams. The geoduck industry brings in eighty million dollars annually in the US and Canada. Today the United States benefits highly from the Asian countries taste for Geoduck meat.
Soy sauce and wasabi are common condiments served with Geoduck meat. Geoduck clams are usually eaten cooked but sometimes are prepared in the raw sashimi style. In fact, they often sell for as much as thirty US dollars per pound. They are highly prized in Asian cuisine today. The first fishery was built in 1970, but there was not much demand for the clam until recent years. The way a geoduck clam feeds is by siphoning plankton in, filtering out the food, and ejecting the waste. Also, geoduck clams do not do much in order to survive, so their bodies do not have much wear and tear. Only sea otters, dogfish, and starfish are strong enough to open and feed on the clams. First, geoduck clams have very few predators.
In fact, this is one of the longest lifespans of any animal species in existence today! There are several reasons for this longevity. Geoduck clams live extremely long lives, on average about 146 years. The average weight of a geoduck clam is between one and three pounds, but there have been examples found of clams that weighed as much as ten pounds! The geoduck clam is the largest burrowing clam found anywhere in the world. The geoduck clam is a large species of saltwater clam that is native to the Pacific coastal regions.
