NOAA Photo Library Image - fish7941

Bottom view of a hydraulic jet dredge developed to harvest surf clams and ocean quahogs previously unutilized. The dredge is towed on the seafloor at depths of 30 to 100 feet, and clams are washed out of sand and gravel by high-pressure jets of water. A v-shaped knife scoops up the clams; other jets are positioned to push the clams into the "cage" of the dredge for bringing to surface.
