This document outlines a 5-year plan to study clam fisheries in Oregon. "We have identified four areas of research and education that require attention. These are: 1) Development of a fishery for the Manila clam Tapes japonica. 2) Study the effects of clamming and management practices on clam populations. 3)...
This is a staff statement for a hearing of the Oregon Fish and Wildlife Commission. The document addresses problems associated with commercial clamming. Some commercial diggers were not selling harvests as required by law, were not properly reporting harvests, and were not paying State fees. Some commercial diggers were taking...
Razor clams from Clatsop Beach (Tillamook Head to Columbia River) were sampled regularly from March through September and periodically the rest of the year. Sport and commercial diggers were interviewed to obtain catch location and number and age composition of clams dug. Random age-length data and wastage samples were collected....
