Base map and data from OpenStreetMap and OpenStreetMap Foundation

In Arctic seas, polar cod (Boreogadus Saida) is the primary forage fish, and is the main source of food for ringed seals and the belugas. This dataset describes the taxonomic identification of Boreogadus Saida captured with the deployment of horizontal nets.

Method Summary

Ichthyoplankton nets were cast from the surface to depths varying from 10 to 100 m, corresponding to the epipelagic layer where age-0 polar cod typically make up >90% of the fish assemblage.

Nets were deployed from 25/05/2018 to 13/07/2018.

Method Summary Hatch dates were determined by otolith age reading. Hatch locations and surface salinity at hatch locations was determined through lagrangian particle modelling. Strontium-88 concentration in the otolith was determined through laser-ablation mass spectrometry.
Laboratory Louis Fortier's lab
Comments A sub-sample of the total zooplankton caught in one net is taken, the species in this sub-sample are all identified and counted. The counts are then raised to estimate the total abundance of zooplankton species in the net.
Variables Measured Fish Taxonomy, Organisms, Presence/absence; count
