Book excerpt: The U.S. Army Engineer District, Seattle is currently involved in a decision making process regarding the designation of open water dredged material disposal sites in Puget Sound and adjacent waters. In 1985 a joint effort was initiated to examine long term requirements and strategies for open-water disposal of dredged materials. The quality of benthic habitats at proposed disposal sites was identified as a major topic of interest in the PSDDA study because of potential impacts to demersal fish feeding habitat. One aspect of benthic habitat quality is the relative amount of trophic support that a given benthic habitat provides demersal bottom-feeding fishes. analytical procedures have been developed to estimate this aspect of benthic habitat quality. These procedures are collectively called the Benthic Resources Assessment Technique, or BRAT. The BRAT analysis involves the collection of two data sets; one which describes benthic biomass in terms of size and vertical distribution in sediments at selected sites, and a second which describes the foraging depth and prey size exploitation pattern of demersal fishes at those sites. The BRAT then estimates that portion of the total benthic infaunal biomass that is both available and vulnerable to predation by target fishes. (KT).

This book was released on 1986 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This evaluation, based on samples taken in June and July, 1986 at 4 study areas (Commencement Bay, Elliott Bay, Port Gardner, and Saratoga Passage), provides comparative assessments of benthic habitat quality at the study areas in terms of potential trophic support for bottom-feeding fishes. The results of this study are particularly relevant to use of the proposed sites by Dover and English soles. Study findings include: 1) Taxonomic composition (at the Order level) of the benthos was essentially similar among all study sites. 2) With regard to total benthic biomass, Alternative sites at Commencement Bay, Elliott Bay, and Port Gardner had consistently higher standing crops of benthos than the respective Primary Sites (although the absolute differences were not striking). 3) Vertical distribution of benethic biomass in the sediment column down to 15 cm was quite similar among all Commencement Bay, Elliott Bay, and Port Gardner sites. Relatively high biomass values were found for the uppermost(0-2 cm) sediment depth zone at both the Elliott Bay and Port Gardner Alternative Disposal Sites. 4) estimates of trophic support potential generally corresponded with total benthic biomass measurements at the various study sites.
