Abstract

Spatial Analysis of Beach Stranding of Juvenile Salmonids by Vessels
Track: Forestry, Wildlife, and Fisheries Management
Authors: Kevin Gabel, Sarah Jenniges

Nearly 1,200 deep draft vessels traverse a 100-mile long section of the Lower Columbia River annually. Recent studies have shown that wakes from a proportion of these passages strand juvenile salmonids, many of which are federally protected under the Endangered Species Act. Stranding is a function of the complex interaction of a number of factors including vessel characteristics, tidal height, fish density in shallow nearshore areas, and channel morphology. The objective of this study was to identify high-risk beaches that are prone to stranding.
