ABSTRACT

Southern bluefin tuna (SBT) are a long-lived late-maturing and highly migratory tuna found throughout the southern temperate oceans except for the more easterly regions of the South Pacific. There is considerable international concern, controversy and scientific debate on the current state and future prospects for tuna stocks worldwide, and what constitute effective policy and management measures for rebuilding stocks which are heavily depleted. In contrast management procedure (MP) for setting the catch limit represents a default recommendation that is automatically adjusted in response to monitored indicators of stock status. The suite of robustness tests included both more optimistic and more pessimistic stock status outlooks, relative to the reference OM. Proposed alternatives to current fisheries management measures include commercial catch moratoria and large-scale marine protected areas.
