Abstract
Catch- and maturity-at-age are two essential input matrices into the West-Atlantic mackerel stock assessment model. Here, we revise both estimation algorithms and provide a comparison with previously presented outcomes. Although the new matrices differed most notably from the old ones for the younger ages (1 and 2), the overall patterns were highly similar and thus resulted in the same perception of the stock’s dynamics. The new methods were however preferred as they guarantee full interannual comparability, and in addition have several other desirable properties (flexibility, transparency, etc.). The 2023 final assessment model was run with the new input data presented in this document.
