The annual average farm-gate value of clam culture in Canada was $ 9.2 million in the last five years (2011-2015). There are numerous commercially important clam species within the United States, though the one most recognized and utilized in shellfish aquaculture operations on the East coast is the quahog or hard clam (Mercenaria mercenaria). As culture methods improve for these species the clam aquaculture industry will likely continue to grow and diversify. “At Sunnybrae we were finding around 20 clams per square metre of lake bed,” said Sue Davies, Aquatic Coordinator for the Columbia Shuswap Invasive Species Society. Oregon clams include the much-prized razor clam, as well as bay clams -- a catch-all term that includes several different species of clams. As the clams grow and reach a “field plant” size they are most often planted and allowed to dig into the sediment of runs covered by mesh or net, or they can be placed in mesh bags on the bottom for grow out.
Larger mechanized equipment such as hydraulic dredges may be available for harvesting larger areas of cultured clams. They could hitchhike in the smallest amount of water in your watercraft and survive to populate another lake. For example, Venerupis philippinarum or Manila clam, which has been introduced . Species Information. It is important to remember that Freshwater Clams will not tolerate any copper-based medications and can be adversely affected by even small levels of copper present in the water. Clams need steady water flow in order to bring them in contact with food items that they can then filter from the water currents. Bay clams are widely distributed on the coast, while razor clams are concentrated on the north coast beaches in Clatsop county. It, too, is fine table fare. Freshwater Clams are filter feeders who sift small organisms, detritus, decaying plant matter and small foodstuffs from the water column. The names themselves are similar in the literature (e.g. One of the interesting things about the clam market is that they are most valuable when harvested and sold at the smaller end of marketable size range, most often called little necks (about 1” in shell height and less than 2” in length). "The larvae of this species are microscopic. Two species may be present in some introduced populations: C. fluminea and C. fluminalis. This is an important measure for all watercraft: boats of all kinds, kayaks and canoes, paddleboards, and inflatables.
Clam is a common name for several kinds of bivalve molluscs.The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds.Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. Since small clams are the most vulnerable to the many predators of the marine environment, a nursery system is usually employed to start.

C. fluminea is often confused with Corbicula fluminalis due to the two species' similar color and texture. Freshwater Clams help keep uneaten food, detritus and decaying plant matter out of the water column, which help maintain water quality and lower nitrate levels.
