ISEMP - Idaho & Oregon: Snake River Tributaries

Biomark, with support from the Nez Perce Tribe and Idaho Department of Fish and Game, installed 22 PIT-tag detection systems in rivers and streams throughout Idaho and Oregon from 2009 through 2013.  The systems, funded by Bonneville Power Administration, detect PIT-tagged anadromous salmon and steelhead as part of NOAA Fisheries Integrated Status and Effectiveness Monitoring Program (ISEMP) http://www.nwfsc.noaa.gov/research/divisions/cbd/mathbio/isemp/index.cfm.  ISEMP is a collaborative effort to evaluate populations and habitat in several major sub-basins of the Columbia River.  The data collected from Biomark PIT-tag detection systems provide valuable information about salmon and steelhead abundance.
