Fish samples in the Labrador Sea and Canadian Arctic (2017-2024)

The dataset is composed of adult fish species captured during the ArcticNet cruise aboard the CCGS Amundsen from 2017 to 2024. Pelagic fish were caught with an Isaacs-Kidd Midwater Trawl (IKMT, 9-m2 rectangular mouth aperture with mesh sizes of 11 mm in the first section and 5 mm in the last section). It was deployed from the surface to depths targeting possible aggregation of fish as recorded by the acoustic echosounder from the ship. Demersal and benthic fish were sampled with a bottom beam trawl (3-m2 rectangular aperture with a headline and a footrope of 4.27 m and a cod-end mesh of 9.5 mm) deployed on the seafloor. The pelagic and bottom trawls were towed at ~3 knots for 10 to 20 min. All fish collected by the trawls were measured and identified at least to the family level before freezing at -20°C. Note: No data was collected from the Arctic during 2020 since there was restricted access due to the COVID-19 pandemic.
