During three cruises in the Mid Atlantic Ridge area in 2016 and 2017, we collected samples of mesopelagic species down to a depth of 600 m. We studied fish behaviour and identified and quantified the species composition of the catches using HD videos (60 frames/s). For species identification and the estimation of the number of siphonophores/m³ we analysed the videos frame by frame using the tool VLC media player. ...
