The Garrison Bay Project, Stock Assessment and Dynamics of the Littleneck Clam, Protothaca staminea
Garrison Bay is a small bay in Washington State, U.S.A. The marine fauna is diversified, with especially large numbers of soft-substrate benthic organisms such as polychaetes and bivalves (Scherba and Gallucci, 1976). One of the popular recreational activities in the bay is clam digging. During the past five years this harvest has been monitored and data collected on the species harvested, the total weight of each digger’s harvest, the size distribution of each species and the time needed to dig each catch. In addition, a periodic survey by stratified random sampling determines the abundance and size distributions of the unharvested standing stock of each species. These latter sampling data are presented for the littleneck clam, Protothaca staminea, the species most commonly taken.
