TRANSITIONS AND RESILIENCE IN THE FROZEN COMMONS : LINKING AQUACULTURE, KRILL FISHERY, GOVERNANCE AND ECOSYSTEM CHANGE IN THE SCOTIA SEA, SOUTHERN OCEAN
The Antarctic krill (Euphausia superba) is a forage fish species that is increasing inimportance for Southern Ocean fisheries and world aquaculture production. However, thisspecies also has a fundamental role in the Scotia Sea food-web and is the main conservationtarget for the region’s natural reso...

The Antarctic krill (Euphausia superba) is a forage fish species that is increasing inimportance for Southern Ocean fisheries and world aquaculture production. However, thisspecies also has a fundamental role in the Scotia Sea food-web and is the main conservationtarget for the region’s natural resource management organization - the Commission for theConservation of Antarctic Marine Living Resources (CCAMLR). The aim of this thesis istherefore to examine the inter-relationship between CCAMLR, krill fishery and the Scotia Seaecosystem in the Southern Ocean, as well as broader socio-economical and ecological settingssince 1970s and measure system resilience. The premise here is that the current krill-regime inthe Scotia Sea must be understood as a complex adaptive system (CAS) of social, ecologicaland economical attributes that operates over different temporal and spatial scales.
