Increase in red king crab (Paralithodes camtschaticus). Insights and key research questions derived from assessing scientific background information using an IEBM lens

Scenario 2. Increase in red king crab (Paralithodes camtschaticus) biomass and distribution
Background information	Reference
The red king crab benefits from increased water temperatures in the Arctic	Stoner et al. (2010)
The red king crab is an economically important species	Hjelstedt (2012)
Red king crabs predate capelin larvae	Mikkelsen (2013)
Capelin is a key food species for other economically important fish species, e.g. cod	Søreide et al. (2008)

IEBM lens
Insights	An increase in the biomass of red king crabs, due to increased water temperature, can potentially reduce capelin production and thus also impact on the production of other fish species e.g. cod and herring
Key research questions	What are the implications of a potential increase and spread of red king crab in the Arctic for capelin production? What are the implications of a potential decrease in capelin production on the production of other economically important fish species like cod? What are the potential economic implications for the fisheries sector of cod and capelin? What are the implications for the co-management strategies of the cod and capelin fisheries? How does this affect local livelihoods, indigenous peoples and the local fisheries industries? Are those activities resilient to such change and could they seize the opportunity to produce King Crab instead? Are there potential global repercussions?
