Patagonian toothfish spawn in deep water around 1, m during the austral winter, producing pelagic eggs and larvae. To minimise the risk of long-term adverse effects on target species, bycatch species, and marine ecosystems, CCAMLR uses a number of compliance systems to monitor fishing activities in the convention area.

This measure, combined with additional surveillance by member nations’ catch documentation schemes has played a significant part in the reduction of IUU fishing for toothfish. In the late s to early s, IUU fishing for toothfish nearly collapsed some fisheries in the Southern Ocean. Patagonian toothfish is caught off the coasts of Chile, Argentina, Peru, Elegginoides, Patagonia, and around sub-Antarctic islands and seamounts.
