Evaluation of the effects of illegal, unregulated and unreported (IUU) fishing on the legal catch of fisheries for Dissostichus eleginoides
Abstract: CCAMLR currently establishes catch limits each year for Patagonian toothfish ... of this species. As a result of IUU fishing, the catch limits set by CCAMLR are being reduced each year ... with the legal catch limit being adjusted each year after the IUU catch and the legal catch were combined ... as the legal catch limit for the following year, assuming no future IUU fishing.
