Population studies of the Pacific razor clam Siliqua patula were conducted on the eastside beaches of Cook Inlet during the summer of 1992. Aerial surveys revealed that the two most popular beaches, Clam Gulch and Ninilchik, received 25% and 59%, respectively, of the overall digger effort during 1992. Age-4 clams provided the largest proportion of the harvest on both Clam Gulch and Ninilchik beaches (30% and 67%, respectively). Abundance of clams at Clam Gulch, estimated by catch-at-age analysis, declined during the late 1970s to a low of 2.0 million in 1981. The population has increased since then to an estimated 8.8 million clams in 1991. Recent-year population estimates from catch-at- age analysis are considered unreliable, and this last estimate will likely decrease with additional data. Estimated total abundance of clams on the Ninilchik Beach study area from onsite sampling was 3,051,291. Estimated exploitation of clams on this beach during 1991 was 18%.
