Invasive Crabs in the Barents Sea

Abstract

The recent invasions of the red king crab (RKC) and the snow crab
(SC) in the Barents Sea represent the sorts of integrated ecological
and economic shifts we may expect as climate change affects arctic
seas. Economic incentives and ecological unknowns have combined
to change the current and potentially future productivity and
profitability of the Barents ecosystem in complex and interacting
ways.
We examine potential ecological-economic trajectories for these
crabs’ continued expansions in the Arctic and how the profitability,
the joint and national management structures in Norway and Russia,
and the uncertainties regarding ecological impacts, co-determine the
potential paths. We use these results and tenets of environmental and
resource economics to suggest improved management strategies that
better integrate the ecological unknowns into management in order to
increase social welfare in the long run.
We compare differences in the ecology and economics of the
two species to enhance understanding of the trade-offs inherent in
managing these economically profitable yet risky invaders. We then
expand the application by using these ongoing invasions to illustrate
the anticipated disruptions (with potentially both positive and
negative impacts) from other introductions or range expansions of
commercial species and the management steps that should be taken at
earlier stages, including monitoring and preventive measures, in the
changing ecological processes to minimize negative impacts.
