Simple Stock Synthesis code and examples

Simple Stock Synthesis

Simple Stock Synthesis (SSS) is an assessment method for application to data-limited stocks that estimates catch limits. It is an age-structured version of other catch-only methods such as DBSRA and CMSY.

The "background literature" folder contains papers on the methods origin and development.

An GUI version of SSS is available using the SS-DL tool (https://github.com/shcaba/SS-DL-tool). The SS-DL tool incorporates the SSS approach into a suite of methods ranging from data-limited to data-rich methods all in one framework/package.

Installation

install.packages("devtools")
library(devtools)

devtools::install_github("shcaba/SSS", build_vignettes = TRUE)

Note: devtools may give this message: "WARNING: Rtools is required to build R packages, but is not currently installed." However, Rtools is NOT required for installing sss via devtools, so ignore the warning.

Once you have installed the sss package, it can be loaded using:

library(sss)

A vignette is not yet available but is being created and will be available using:

vignette(sss)

Once installed, the SSS approach can be run through the sss() function, or using the SS-DL tool GUI (https://github.com/shcaba/SS-DL-tool).
