| Notes | "The objectives of this study were: (1) to continue mapping the distribution of bay clams in Oregon's estuaries, (2) to assess the effects of mechanical harvest on subtidal claws and habitat, and (3) to evaluate the success of planting hatchery produced and released juvenile clams in selected Oregon estuaries." (p.1) Includes maps of clam, shrimp, eelgrass, and algae distribution in Umpqua and Coos Bays, and of areas approved for commercial clam harvesting in Yaquina and Coos bays, Gives biomass estimates for Yaquina Bay. Gives commercial clamming statistics. Discusses sediment changes after clam harvest. Numerous charts and tables. |
