dc.description.abstractSpecimens of Protothaca staninea (Conrad), the littleneck clam, were collected by transecting three beaches in Galena Bay, Prince William Sound, Alaska, during the summer months of 1971 for a study of recruitment, growth and distribution. The average size of Protothaca in Galena Bay at the end of the first growing season is approximately 2 mm in length. At any age, Galena Bay littlenecks are smaller than those from British Columbia. In Galena Bay, eight years are needed for P. staminea to reach a length of 30 mm as compared to three years for individuals from British Columbia. In Galena Bay, the intertidal distribution of P. staminea generally follows a bell-shaped curve with upper and lower extremes occurring between the tidal heights of +0.73 and -0.76 meters. Young-of-the-year are essentially epifaunal, and the majority of the specimens of all age classes are found within 4 cm of the sediment surface. The number of individuals surviving annual recruitment into the populations studied was variable.en_US
