Conservation of Krill Stocks

In order to reduce the detrimental effects observed on surrounding dependent organisms, within both marine and terrestrial ecosystems, quota systems, as well as no-take-zones, have been put into action in the more vulnerable areas (Georgia Seas); as well as certain regions enforcing ‘no fishing’ regulations during the breeding seasons of many species. Nevertheless, even with the quotas in place, Antarctic krill was regularly being harvested at approximately 100,000 tonnes per annum (Nicol & Foster, 2003); though in recent years this figure has increased and continues to do so (Figure 15).
