Skildring:CRIMAC survey with G.O.Sars, 2022.11.27-2022.12.03. From Tromsø and Kvænangen to Lofoten, Vestrålen and Myre. We test new ideas and methods in using scientific echosounders and sonars to study fish. We study herring in Kvænangen fjord with broadband echosounders pointing downwards and sideways to port and starboard. We test and measure the size of fish directly from echosounder data. We test various aspects of broadband echosounder use on fish aggregations. We travel to Lofoten/Vestrålen to aid

Skildring:Echogram of station 364 (38 kHz) with depth profile and predictions of blue whiting (blue), herring (red), mackerel (green), and mesopelagic fishes (orange). Images at top are from the positions indicated along the trawl’s path and show the bounding boxes calculated by the object detection model. The size of the bubbles in the centre panel are proportional to the number of fish predicted per minute. The stacked histogram at bottom similarly shows the number of each fish species per minute but av
