Multi-Stock Assessment.

multiSA

Multi-stock assessment with RTMB

multiSA (Multi-Stock Assessment with Regional Spatiotemporal dynamics) is a multi-stock, spatially-explicit age-structured model.

With explicit seasonal stock availability and movement, multiSA is intended for use in mixed fisheries where stock composition can not be readily identified in fishery data alone, i.e., from catch and age/length composition. Models can also be fitted to genetic data, e.g., stock composition of catches and close-kin pairs.

Funding for development of multiSA is provided by the NOAA Fisheries Bluefin Tuna Research Program (BTRP Grants NA23NMF4720184 and NA24NMFX472C0008-T1-01) in collaboration with the Ocean Foundation.

Atlantic bluefin tuna (Thunnus thynnus) is the first intended case study.
