Description: An average of approximately 200,000 pounds of bay clams were harvested annually in Oregon for the years 1943-49, inclusive. The commercial harvest of bay clams is composed of the gaper, cockle, and softshell clams. The recreational, or noncommercial, harvest of bay clams is composed mainly of the gaper, cockle, softshell, butter, and littleneck clams, and occasionally the bent-nose, sand, geoduck, and bodega tellen clams. Recreational production is estimated for selected time periods for Yaquina, Netarts, and Tillamook Bays. A description of the common bay clams of Oregon with general information on common names, habitats, relative abundance, and method and place of harvesting is presented. A description of the bay clam producing areas in the Nehalem, Tillamook, Netarts, Nestucca, Salmon, Siletz, Yaquina, Alsea, Siuslaw, Umpqua, Coos, and Coquille Bays is presented. A discussion on the condition of the stocks of the gaper, cockle, and softshell clams is presented.--Summary.
