Fish Assemblages of Rocky Banks of the Pacific Northwest. Final Report. Supplement.

摘要

The general objectives was to obtain information on the fish resources of outer continental shelf rocky banks of the Pacific northwest. The specific goal was to produce a database of fish densities and fish-habitat associations among years and banks for assessing the impacts of future offshore drilling and other mining activities. The limits of that value would depend upon the temporal and spatial scales over which the database was relevant and representative. From 1988 to 1990, the fish assemblages and fish-habitat associations at each of three major banks off Oregon were analyzed. In addition to characterizing the fish assemblages and fish-habitat associations at Stonewall Bank, the first day-night comparisons of fish distributions on a Pacific northwest rocky bank were completed. In September-October 1991 the manned submersible Delta ran visual belt transects at six fixed predetermined stations at Stonewall Bank. The 1991 final report should be referenced for details concerning background, sampling design, methods, and analytical design.
