"Poster" Tests of a Video Lander System as a Survey Tool on Oregon's Nearshore Rocky Reefs

 

Developing stock assessments for demersal fishes living on nearshore rocky reefs in the Pacific Northwest has been hampered by a lack of effective and affordable survey techniques for these habitats. The reefs are mostly untrawlable, frequently extend beyond diveable depths, can have strong currents, and spatially complex habitats that make remotely operated vehicle (ROV) surveys difficult at times. Very low limits on total mortality for some overfished rockfish (Sebastes) species can also restrict conventional survey techniques, like longlining, because research “take” can result in the closure of commercial and recreational fisheries. We report on the design and field testing of a video lander as a potential survey tool for demersal fishes inhabiting Pacific nearshore rocky reef systems.
