Casal2 is an open-source age or length structured population dynamics modelling package. The Casal2 software implements generalised age- or length-structured population models that allow for a great deal of choice in specifying the population dynamics, parameter estimation, and model outputs. Casal2 is designed for flexibility. It can implement an age- or length-structured models for a single population or multiple populations using user-defined categories such as area, sex, and maturity. These structural elements are generic and not predefined, and are easily constructed. Casal2 models can be used for a single population with a single anthropogenic event (in a fish population model this would be a single fishery), or for multiple species and populations, areas, and/or anthropogenic or exploitation methods, and including predator-prey interactions.

This repository is a clone of Casal2 of https://github.com/CASAL2. It is intended to have additional bug fixes and enhancements for potential inclusion into the main Casal2 codebase.
The most recent development version of Casal2 from this repository is available from https://github.com/alistairdunn1/CASAL2. The most recent official version of Casal2 is available from https://github.com/CASAL2, but that may not contain all of the bug-fixes and enhancements found in this version.
An R package that will read and write Casal2 model input and output files can be installed using
devtools::install_github("https://github.com/alistairdunn1/CASAL2/", subdir = "R-libraries/casal2")The r4Casal2 R package adds helper and access functions for R to assist with postprocessing Casal2 output. It can be found here (r4Casal2) and installed using
devtools::install_github("https://github.com/alistairdunn1/r4Casal2/", subdir = "r4Casal2")r4Casal2 has a publicly hosted book found here which demonstrates functionality of the r4Casal2 R package.
The r4Casal2 package is a update of r4Casal2 from https://github.com/NIWAFisheriesModelling/r4Casal2.
