Global Arctic: Arctic Fisheries in an Uncertain Future

This lecture by Dr. Franz Mueter explores the current state of Arctic fisheries, highlighting the latitudinal gradients in fish species richness and biomass, the large-scale commercial fisheries around the Arctic edges, and the trends in fish biomass by latitude. It also discusses the northward expansion of fish populations, changes in energy flows and food webs, and the potential future scenarios for Arctic fisheries, including the expansion of boreal fish communities into the Arctic and the impact on true Arctic species. Precautionary measures to prevent unregulated fishing, such as the management of Exclusive Economic Zones and the closure of US Arctic waters to commercial fishing, are also addressed.
