Geoduck tubes do more than just shield cultured geoducks from predators. They also create an oasis for native clams, such as cockles (Clinocardium nuttallii, pictured here), to settle and grow. Cockles are becoming harder to find on several beaches in Puget Sound. The protection of mesh tubes may provide a new twist for cockle conservation. Researchers are partnering with geoduck farmers and tribes to explore the extent that cockles populate cultured beaches, whether cockle presence impacts geoduck, and how cockles could be transplanted to non-cultured beaches to restore populations and tribal harvest of this important traditional food.
