Overview
Row
While a formal MSE process has not yet been launched for South Atlantic
albacore, the ICCAT Commission recommended starting MSE process for
Southern Albacore and adopting a candidate Management Procedure (MP) by
2029 (Rec. 24‑09). A set of tentative operational objectives to guide
MSE design was provided.
Rec. 24‑09 outlines the initial
operational management objectives to support the development of a
Management Strategy Evaluation (MSE) for South Atlantic albacore.

Summary
Row
Operating model development is anticipated in coordination with updated
assessments by the SCRS Albacore Species Group
Performance metrics
and stakeholder engagement will follow SCRS guidelines.
A set of
operational objectives to guide MSE design (Rec. 24‑09):
Stock
status: ≥ 60% probability of remaining in the green quadrant of the Kobe
plot over a 30-year projection.
Safety: ≤ 15% probability of falling
below BLIM at any point in the projection period.
Yield: Maximize
overall catch levels.
Stability: TAC changes between management
periods should not exceed ±20%.
A proposed 3‑year management cycle
for initial implementation.
A provision for revising these objectives
by Panel 3, in consultation with the SCRS Albacore Species Group, with
final objectives to be submitted by 2029.
These objectives define a
transparent decision-making framework for operating models and candidate
MPs during the S‑ALB MSE process.
