Hydroacoustic monitoring of anadromous fishes in the Roanoke River

July 2007 - June 2013


Participating Agencies

  • North Carolina Wildlife Resources Commission

Anadromous fishes spend the majority of their adult lives in the ocean and make yearly migrations (runs) into coastal rivers to spawn. These species are targeted by commercial and recreational fisheries both in the ocean-estuarine environment and during their runs into coastal rivers. Information on abundance of these important species is needed in order to properly regulate harvests and to assess the effectiveness of rebuilding efforts. The primary objective of this study is to estimate the size of spawning runs of American shad, striped bass, and other anadromous species. A related objective is to gain a detailed understanding of migratory behavior in order to design an effective monitoring program and interpret the hydroacoustics data.
