1 Ecosystem Monitoring Project 2014 Fish Sampling Update Lyndal Johnson, Sean Sol, Dan Lomax, Paul Chittaro, David Teel, and Gina Ylitalo NOAA Fisheries Northwest Fisheries Science Center, Seattle, WA, USA Lower Columbia Estuary Partnership Science Workgroup Meeting October 28, 2014

2 2014 Update 2014 Field sampling Fish habitat occurrence and salmon health at four of six trends sites (limited sampling at Ilwaco Slough and Secret River) Restricted seasonal sampling (February through July) Additional data from 2013 Chinook salmon stock composition Bonus data Baseline PAH exposure for USGS coal train study in the Columbia Gorge

18 Summary of Findings Consistent patterns for fish community characteristics and salmon occurrence at Welch Island, Whites Island, and Campbell Slough Low species diversity, few non-native species at Welch and Whites Island; more at Campbell Slough Higher Chinook salmon density, more fry, more unmarked fish at Welch Island and Whites Island than at Campbell Slough More interior Columbia Chinook salmon stocks at Campbell Slough than at Welch Island or Whites Island Franz Lake highly variable trends difficult to evaluate because of limited access/sampling No chum and few coho in 2014 Increasing number of sockeye salmon in catches
