"October 1, 1979 to September 30, 1980." "We continued our studies on the clam resources in Oregon's estuaries. Our objectives were: (1) to monitor the commercial harvest of subtidal clams in Yaquina and Coos bays and evaluate the effects of mechanical harvest on subtidal clam populations and habitat; (2) to...
"Annual report : October 1, 1980 to September 30, 1981" "During the year we continued our studies on the clam resources in Oregon's estuaries. Our objectives were: to collect data for developing a scientifically sound clam management database and to refine techniques for assessing the potential for a commercial clam...
"Completion report : October 1, 1979 to December 31, 1981" "We completed Our assessment of commercial clam harvest potential in Tillamook, Yaquina and Coos bays. All three bays contained commercial quantities of clams. Detailed studies in Yaquina Bay in 1981 revealed a biomass estimate of 2.6 million pounds (1,179.1 mt)...
"We continued our studies of the distribution of bay clams in Oregon's estuaries, Maps showing the distribution of clams and vegetation type in Umpqua and Coos bays are presented. . . We continued to monitor the growth of laboratory produced clams planted in Netarts and Yaquina bays." (from the Abstract)...
