The WGNAS-SalmoGlob ToolBox supports and promotes Atlantic salmon stock assessment by the ICES Working Group on North Atlantic Salmon (WGNAS). The ToolBox supports the Bayesian integrated life cycle model developed for the stock assessment and provision of multi-year catch advice.

All contents presented are from data and outputs of models from ICES WGNAS 2021 that held 22-31 March 2021, remotely.

Time series of data used is 1971-2020.

Data and outputs presented for Scotland (East and West) are preliminary and non official data that should be updated definitely by the end of May 2021.

. DataCollect - Upload data as .csv files to update the online salmon database. [restricted access only; now inactive; accessible via ID and password later]

. DataVisu - Visualize all inputs used in the Life Cycle Model. [public access]

. Hindcast - Investigate the trends in a selection of variables predicted by the model fitted on the historical series of data (from 1971) and compare them to corresponding observed values when available.

. Forecast - Explore the model predictions under different catch options and quantifies the probability to achieve management objectives. [public access]

. Export - Download all inputs used in the life cycle model as .xlsx templates for the yearly data call for single stock units or fisheries, or directly as Nimble objects (i.e. formatted as R-lists of data inputs with model variable names). [public access]

Here you can download the data currently used by the Life Cycle Assessment regarding your specific juridiction. This constitutes a template that you may fill with the updated data for the next meeting of the ICES Working Group for North Atlantic Salmon Assessment (WGNAS). This template is a .xls file with as many sheets as variables should be informed. Please keep the indexes and column names as they are in the template. To be accepted, the data should be provided up to the year appearing at the bottom of each sheet.

The 'Greenland' file contains all the information relative to the Greenland fisheries on shared stocks, including catch statistics and origin reassignation based on molecular analyses.
