Fish activity and movement information derived from acoustic monitoring of a restored Lake Erie coastal wetland from 2011-2014

These data describe estimates of large-bodied fish activity and their direction of movement with respect to a restored wetland located in Ottawa National Wildlife Refuge, Oak Harbor, Ohio, USA. Acoustic sonar technology was used to monitor fish activity following restoration and reconnection of a hydrologically isolated wetland pool to the wider Lake Erie system. Fish activity was measured during 56 multi-day observational events spanning four years following reconnection (2011-2014). Each hour of acoustic data was processed as an observational unit using a combination of commercial and purpose-built software. The resulting dataset quantifies fish activity and characterizes this movement as immigration into or emigration out of the restored area for 2,022 hours of observation.
