Recorded as part of a scientific research project conducted by the Department of Fisheries in collaboration with the University of Western Australia and CSIRO, this project aimed to describe and compare fish assemblages of the upper slope (100-600 m) along the west and north coasts of Western Australia. The footage was collected from two research surveys in March and November 2010, onboard the Research Vessel Naturaliste. A total 150 stereo-Baited Remote Underwater Videos were deployed, recording a total of 1358 fish from 78 different species. The number of species and total numbers of individual fish decreased with depth. Fish assemblages at 200 m were very different from fish assemblages at 400 and 500 m which were more alike. As depth increased the fish assemblage was made up of a variety of different sharks and rays.
