"This is the three hundred and twenty second Technical Report of the St. Andrews Biological Station." Includes bibliographical references (p. 6). "Towfish (sidescan and video) and echosounder 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 echosounder data could be used independently of one another. However, the towfish data were very useful for ground truthing echosounder 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”--Abstract, p. v.
