Fish Commission By 1948, Oregon’s clamming regulations spilled over into fifty-one different sections of administrative rules. They were “cumbersome” at best. The previous legislative session had repealed many outdated laws but kept them in effect until the Fish Commission could study the issue and propose new regulations. The Commission had been studying the matter for a little more than a year in Tillamook, Yaquina and Coos bays and in this document gives its first recommendations, primarily focusing on the gaper, or “horse,” clam fishery.

  Citation × Citation Citation Abstract Copy Title: Horseclam condition studies Author: Marriage, Lowell D., Oregon. Fish Commission The first regulations restricting clamming in Oregon were put into effect in 1948. Initial rules barred clamming from January 1 through June 30; clammers objected that this was too restrictive and lobbied for more time to take shellfish. This 1949 document examines the fat gaper or horseclam, to see when its condition was at its best in Oregon, in order to determine the best times for open clamming seasons. The authors concluded that they needed more information about the winter months before they could contemplate a change. This document gives a good example of earlier natural resource management and decision-making. Includes charts and hand-drawn illustrations of clams.

Fish Commission, Demory, Darrell This report is an update of shellfish investigations from April 1961-March 1962. It includes a summary of observations of clam conditions, and discusses a Netarts Bay clam mortality, which drove the Fish Commission to ask the Tillamook County Court to inform them of any future construction projects involving estuaries. It brings up a potential Highway 101 reroute across two clam beds, and the research that was to be done on those beds. The final significant subjects discussed are personal-use and commercial clam fisheries, including number of diggers, and general information on clams dug.
