Stable Isotope Analyses of Arctic Coast 2021/2022 Samples

Fisheries and Oceans Canada (DFO) has been conducting an ecosystem baseline sampling survey among communities of Hudson Bay, and the Beaufort Sea. Fishes will be collected, sampled and muscle and liver will be removed in order to identify prey items of coastal fishes. Tissues will provide a synthesis of fish diet over the course of a 50 day period, which will then be used for the progress of a master’s thesis and for subsequent monitoring in the Hudson Strait area. Additionally, invertebrates and sediment collected in the same region will be collected and will be analysed for stable isotopes (δ¹³C, δ¹⁵N, δ³⁴S) in order to compliment the information gathered among coastal fishes.
