Abstract
This article describes a framework within which an initial strategy could be developed for managing commercial exploitation of marine living resources of the Southern Ocean, particularly of krill and fish, in accordance with Article II of the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR). Quantitative predictions involving multi–species models are needed to assess any indirect impacts of fish or krill exploitation, and also for management to restore depleted populations. This article recommends research to provide the knowledge necessary for the models (identifying key species, estimating their demographic status, and experimental interference), and suggests interim management action to delimit management areas, agree target levels for stock–size, and monitor stocks. Early efforts to model the fishing operation are particularly recommended.
