An illustrative management procedure for exploring dynamic feedback in krill catch limit allocations among small-scale management units
average krill catches per SSMU associated with each MP. The key assumption made here is that data will be ... modified if, for example, no krill abundance indices are available. Given that “future” data are required ... subdivision of the precautionary catch limit for krill among 15 small-scale management units (SSMUs) in the ... subdivide the krill catch between SSMUs. Different MPs are then simulation tested with their performances ...
