This is the reference scenario for Albacore for the 2012 Stock Assessment.

Stock Assessment of Albacore in the south Pacific Ocean Rev 1 (29 July 2012), Hoyle, S, J. Hampton and N Davies, Oceanic Fisheries Programme, Secretariat of the Pacific Community, Noumea, New Caledonia

This working paper presents the current stock assessment of albacore tuna (Thunnus alalunga) in the South Pacific Ocean. The assessment, like the previous assessment (Hoyle 2011), uses the integrated stock assessment model known as MULTIFAN-CL (or MFCL), under the assumption that there is a single stock of albacore tuna in the south Pacific ocean. The model is age (20 age-classes) structured and the catch, effort, size composition and tagging data used in the model are classified by 30 fisheries and quarterly time periods from July 1960 through June 2011. The assessment included a range of model options and sensitivities that were applied to investigate key structural assumptions and sources of uncertainty in the assessment.
