Towfish (sidescan and video) and echo sounder surveys were utilized to examine bottom type and macrophyte cover within the area of two coastal marine finfish aquaculture sites, one in New Brunswick and one in Nova Scotia. Both towfish and echo sounder data could be used independently of one another. However, the towfish data were very useful for ground truthing echo sounder based classifications. All survey data were placed into a GIS which could be used to answer management questions such as the placement of cages at sites, benthic impacts and baseline conditions to determine long term changes.<\/span><\/p><\/div><\/div><\/div>", "mapName": "Exploratory_Video_Sidescan_Echosounder_Survey_Jordans_Bay", "description": "
