Remotely operated vehicle surveys of rockfish conservation areas in British Columbia, February 2009–July 2011 / by D.R. Haggarty ... [et al.]. : Fs97-6/3189E-PDF

“As part of an overall Rockfish Conservation Strategy in British Columbia (BC), Canada, new spatial management measures were designated, the later referred to as Rockfish Conservation Areas (RCAs), which prohibited most recreational and commercial fishing within their boundaries. Between 2002 and 2007, 164 RCAs were implemented throughout the BC coast. Non-intrusive visual surveys were then developed to study fish communities and assess stock status and habitat of inshore rockfish. Between 2009 and 2011, seven visual surveys were conducted at 47 RCAs and adjacent fished areas in southern BC using a Deep Ocean Engineering Phantom HD2+2 remotely operated vehicle (ROV). In total, 424 transects were completed in a paired sampling design over similar rockfish habitat both inside and adjacent to the RCAs. This technical report provides a summary of the visual surveys used to initially assess RCAs in BC and details the methods used to plan the visual survey transects, collect visual data, analyze recorded video, process the transect track lines, and manage the database"--Abstract, p. vi.
