Clams dug by razor clam diggers were sampled from March through September. The sampling day and area were selected randomly according to a method suggested by our statistician. The number of clam digger trips and the number and age of the clams were noted for the personal use and commercial...
Personal-use razor clam diggers were sampled on alternate minus tides from April to September. The number of diggers and the number and age composition of clams dug were noted. Wastage was sampled each tide series.
This report discusses public interaction with personal-use fisheries. It also discusses reasons for razor clam violations and means taken to try and decrease them. Finally, it gives the total harvest and age composition data, and contains the results of a survey of clam diggers on Clatsop County beaches for 1965.
The personal-use razor clam fishery was sampled from April to September 1964 for number and age composition of clams dug and number and distribution of diggers. A wastage estimate was also determined.
In 1960, the Army Corps of Engineers was planning to extend the jetties and to deepen the channel at Yaquina Bay. The Corps proposed to dump its dredging spoils in Sally's Bend, a highly productive part of the bay. In response to this request, in the summer of 1960, Fish...

"The Oregon fishery for Dungeness crab has a long history. Catch records have been kept for this fishery since 1889. The management strategy for Dungeness crab is derived from these records and from our knowledge of crab biology. Management of a single species fishery such as this should be a...
Dungeness crab migration along the coast and movement in and out of bays and estuaries has been studied by Cleaver (1949) in Washington, Waldron (1958), and Snow and Wagner (1965) in Oregon. Tagged crabs were recovered up to 133 miles from the point of release and a free interchange between...
"The sport/commercial interaction concerning Dungeness crab in our estuaries is heating up again. The shellfish staff has discussed this at length and agrees.that the interaction is an indication that our bay crab regulations need to be reviewed. There are currently two issues that need to be resolved: 1) The sport/commercial...
"As the human population has grown, the recreational and commercial use in our estuaries has increased as well. Many people have more leisure time while others facing economic pressures have turned to natural resources to supplement their food needs and/or income. The increased demand has resulted in conflicts of philosophy...
