The State Police in Astoria informed the Fish Commission on October 12, 1970, that some 100 crab pots were in the ocean in 3-10 fathoms of water near Cannon Beach. This is about 23 miles south of the Columbia River within the 3-mile limit. According to one local crab fisherman,...
This is an Oregon Dept. of Fish and Wildlife exhibit for a meeting of the Oregon State Fish and Wildlife Commission. "Problem: Oregon crab fishermen are concerned that 4-3/8" escape ports in crab pots allow too many legal male crabs to escape. Requests have been made to determine whether or...
Oregon Fishermen in Ocean Observing Research (OrFIOOR) is a cooperative research program between ocean scientists and fishermen in the Pacific Northwest. Dungeness crab fishermen attach sensor packages (temperature and dissolved oxygen) to crab pots. The pots serve as platforms of opportunity for ocean observing. This study examines three principle questions...
"This report concerns one aspect of the marina permit evaluation process: water quality impacts related to marina circulation and flushing efficiency. These physical properties vary with the wind, tide range, water density and physical dimensions of a marina. Water quality is affected by the degree of flushing, and sediment redistribution...
An innovative attempt to fish for crabs with helicopters in early 1977 upset some traditional crab fishers, who "claimed that prolonged flight at high speeds would cause delayed mortalities in crabs that were returned to the water. A study was done November 3-December 1 to provide insight into that claim....
"Prepared for the State/Federal Dungeness Crab Management Program, Policy Committee Meeting, April 1974." "At the present time most traps used in the Dungeness crab fishery have at least one escape port for the purpose of allowing small crabs to escape. The problem is that there is considerable variation in the...
This is an exhibit made by the Oregon Department of Fish and Wildlife before a meeting of the Oregon Fish and Wildlife Commission. The report addresses the need for a "destruct device" to stop lost crab pots from continuing to fish. Today, Oregon crab pots must use biodegradable twine in...
"Prepared for the State/Federal Dungeness Crab Management Program. May 1974." "One of the initial objectives of the State/Federal Dungeness Crab Management Program is to evaluate crab mortality caused by certain fishery practices. The areas of most concern include mortality caused by trawling, handling of softshell and sublegal crabs, lost pots...
Coastal foredunes protect lives, infrastructure, and ecosystems during severe winter storms. In the U.S. Pacific Northwest (PNW), coastal foredune geomorphology is determined by both physical and ecological mechanisms. Before the 1900's, the native plant Elymus mollis was the dominant dune grass and dune morphology was largely determined by sediment supply...
