A new study conducted by the Fisheries and Marine Institute of Memorial University of Newfoundland, in collaboration with the Arctic Fishery Alliance, provides the first data on the local and regional abundance estimates of the Greenland shark — one of the most elusive and largest living species of shark. The findings from the study are the first step toward fulfilling a major knowledge gap that is currently preventing assessment of population status needed for the management of the species.
Between July-September of 2015 and 2016, a total of 31 baited remote underwater video (BRUV) camera deployments were conducted in the deep waters of Nunavut in the eastern Canadian Arctic, aboard the Arctic Fishery Alliance vessel Kivivq I. The BRUV was equipped with SubC’s 1Cam and Aquorea LED mounted on a weighted aluminum frame that was tethered to a surface buoy.
The successful deployment demonstrates how minimally-invasive technologies can be used to estimate deep-water populations.
