Overview
Row
While a formal Management Strategy Evaluation (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 by 2029 (Rec. 24‑09). A set of initial
operational magement objectives to guide MSE design was
provided.
Rec. 24‑09 outlines the initial operational management
objectives to support the development of a MSE for South Atlantic
albacore.

Summary
Row
Operating model (OM) 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 initial operational management objectives (MOs) 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 MOs by Panel 3, in
consultation with the SCRS Albacore Species Group, with final MOs to be
submitted by 2029.
These MOs define a transparent decision-making
framework for OMs and candidate management procedures during the S‑ALB
MSE process.
