"In response to uncertainties regarding the nature of bottom sediments in a mixed fisheries area, an imagery survey was undertaken north of Grosse-Île (Îles-de-la-Madeleine, Quebec) as ground-truthing for existing multibeam acoustic data. Digital stills from video cameras were used to establish bottom types in contentious areas, and the resulting classification was the basis for recommendations that allowed the coexistence of a lobster fishery and mobile-gear-based flatfish and mollusc fisheries. The project demonstrates how low-cost bottom imagery surveys can be used to validate data collected using other methods"--Abstract, p. v.
