Biological data of Arctic cod larvae and juveniles in the Canadian Arctic: ArcticNet 2005-2021

Larval and juvenile Arctic cod were sampled in the Beaufort Sea, Baffin Bay, Hudson Bay and in the Canadian Archipelago through ArcticNet surveys 2005-2021 onboard the NGCC Amundsen. The sampler consisted of a rectangular metal frame carrying side by side two 6-m long, 1-m2 mouth aperture, square-conical nets with 500 & 750 um mesh. It was deployed in an oblique tow down to a depth of ~90 m, at a ship speed of 1 m s-1 (2 knots) and a cable angle of 60º on the horizon. All fish larvae and juveniles were sorted from the samples and preserved in 95% ethanol. The datasets include morphometric measurements (standard length and width), hatch date, growth rates and diet of Arctic cod larvae and juveniles (4-62 mm). Note: No data was collected uring 2020 since there was restricted access due to the COVID-19 pandemic.
