Hydroacoustic Estimates of Abundance and Spatial Distribution of Pelagic Prey Fishes in Western Lake Superior

Lake herring ( Coregonus artedi) and rainbow smelt ( Osmerus mordax) are a valuable prey resource for the recovering lake trout ( Salvelinus namaycush) in Lake Superior. However, prey biomass may be insufficient to support the current predator demand. In August 1997, we assessed the abundance and sp...
