Contribution à la description de l'habitat des loups de mer (Anarhichas spp.) près de la péninsule gaspésienne par vidéo remorquée et relevés acoustiques multifaisceaux.

This report presents the results of several initiatives that examine the potential habitat of wolffish (Anarhichas spp.) in the Gulf of St. Lawrence and in particular near the Gaspé peninsula. The habitat features were examined at different spatial scales: by towed video, multibeam acoustic surveys and an examination of historical catch data. High-resolution bathymetry and backscatter coupled with information extracted from video allowed for a detailed description of environments known to be used by wolfish. Features believed to be favourable to wolfish were identified on both survey sites, including shelters and glacial scours. The resulting information is presented within the attached multimedia DVD-ROM. The complimentary nature of these methods and the management implications for a species at risk are discussed.
