Aquatic Disposal Field Investigations, Columbia River Disposal Site, Oregon. Appendix E. Demersal Fish and Decapod Shellfish Studies.

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.
