| Bay Clams |
Oregon estuaries are rich with many species of clams, although only a few of these species are commonly harvested. Gaper, butter, cockle, littleneck, and softshell are primarily harvested due to their abundance, size, and taste. A wide variety of other bivalve species are found in Oregon estuaries, but not commonly harvested due either to their scarcity or lack of palatability.
Successful clamming does require some knowledge and preparation. Before clamming, harvesters should be aware of weather, regulations, closures, responsible harvest, and techniques.

Gaper Clams Tresus capax are found in several Oregon estuaries.They are known by a variety of names including blue, empire, horse and horseneck clams.They are Oregon's largest common clam. Geoducks can grow much larger (as much as 10 pounds!) but are rarely found south of Puget Sound in Washington. There are two species of gaper clams in Oregon. Tresus capax is by far the most common, Tresus nuttalli is found in most estuaries that have gapers but are rarely harvested.

Butter Clams (Saxidomus gigantea) are found throughout Oregon's nearshore areas and larger estuaries. Butter clams are excellent burrowers and are found abundantly in shell, sandstone, and even rocky areas, however due to the ease of digging, butter clams are most often harvested in sand and mud substrates. Butter clams are most often found in large estuarine systems, such as Coos, Tillamook, and Yaquina, because of their higher salinity preference. They are known by a variety of names including Washingtons, Martha Washingtons, Beefsteak, Quahog.

Cockle The most common cockle found in Oregon is the "Heart cockle". This common name relates to its scientific name Clinocardium nuttallii. Translated from Latin this name means "Nutall's sloping heart".
The species name "Nuttallii" comes from the person who first described the species. Thomas Nuttall was a well respected botanist, orinthologist, and explorer of the 19th century. While exploring the Pacific Northwest in an 1830s expedition, the heart cockle was among the specimens he collected and described. Those familiar with taxonomy will likely recognize his surname from several species of flowers and birds.

Softshell (Mya arenaria) Softshell clams occur in almost all of Oregon’s estuaries and their range can extend very high into the estuary. In Coos Bay, for example they are found commonly in places as far as 30 miles from the ocean inlet.
Softshell clams are native to the East coast, where they are an important commercial fishery. They are believed to have been introduced to Oregon in the late 1800s, timed with the attempt to begin a fishery for the eastern oyster.
