Researchers of IMARES leading the Dutch part of this year's North Sea herring acoustic survey and report from research vessel the Tridens. During the past few hauls they were trialling a GoPro camera in the net. The aim of this was to get a better picture of "what is entering the net at what depth and time".

The researchers will be on board the Dutch Fisheries Research Vessel Tridens to survey the area on a systematic, predefined cruise track. The combined internationally coordinated effort will deliver an estimate of the herring stock size in the North Sea.
