This repository provides a detailed specification of the Jack Mackerel Joint Model (the JJM model). This model is recognized and used for Jack Mackerel assessment at the SPRFMO Convention. The document includes:
- Algebraic specifications of the assessment model, including the mathematical equations that model the population dynamics of Jack Mackerel.
- Functions defined in the model code to obtain important quantities such as:
- The Maximum Sustainable Yield (MSY)
- Biological Reference Points (BRPs)
- Catch projections
For this purpose, we have analyzed the model code located at this repository. The document also covers:
- Input data (dat and ctl files) and key parameters for the assessment, including parameters to be estimated.
- Steps to follow for the installation of the resources and running the model.
Finally, a case study is used to illustrate the use of the JJM model
