| According to the Oregon Division of Fish and Wildlife, this clam is present in nearly every Oregon estuary (http://www.dfw.state.or.us/mrp/shellfish/bayclams/dig_softshell.asp). In Washington, they are less popular than Butter Clams (Saxidomus giganteus) or Littlenecks (Leukoma staminea- Pacific Littleneck; Venerupis philippinarum- Japanese Littleneck). However, commercial culture is taking place on private grounds in Skagit Bay and Port Susan (Washington Department of Fish and Wildlife 2012, http://wdfw.wa.gov/fishing/shellfish/clams/eastern_softshell.html). | ||
