Description

Abstract: This report summarizes the results of our bay clam studies in 1996. Activities summarized include recreational and commercial clam fisheries. The tables and figures included give an historical overview of clam harvesting activities and are presented in a manner to allow future analysis to show trends of changes in stock status and fishing activities. Recreational clam digger interviews were conducted annually on each of the major clam harvesting tideflats of the Tillamook, Yaquina, and Alsea estuaries. Also, the lower Umpqua triangle was added for 1991. Recreational clam digger interviews for 1992 were totally eliminated due to budgetary restraints for the first time since 1976. We decided to initiate a volunteer recreational clam use survey for selected estuaries in 1993. Volunteers conducted 1,902 interviews in 1996 during selected low tides from April through July at key locations in Tillamook, Yaquina, and Alsea bays. Volunteers examined 25,267 clams and gathered valuable data concerning catch per effort, species composition, digger origin, and peak use. Prior to the recent volunteer program, staff effort averaged about 1,200 interviews each year at a relatively high cost of staff time and money, compared to the volunteer program. We hope to expand this volunteer program to cover other estuaries for 1997. These data are presented in Tables 1-9, and Table 10 shows peak counts of clam diggers taken at low tide for each of the surveyed tideflats.
