Title: Aquatic Disposal Field Investigations, Columbia River Disposal Site, Oregon. Appendix E. Demersal Fish and Decapod Shellfish Studies.
Abstract: Abstract : Information is provided on 51 finfish and 13 decapod shellfish found at five sites off the Columbia River mouth. The effects of a controlled sediment release by hopper dredges on these indigenous species were studied between October 1974 and April 1976. An initial nine-month phase provided biological information at four sites with a fifth site included in July 1975, as an experimental deposition area. The dredges HARDING and BIDDLE released 548,519 m(3) of sediment between July 9 and August 26, 1975. Sampling continued during and after sediment release until april 1976.
