Length-Based Spawning Potential Ratio (LBSPR)

Build Status AppVeyor Build Status CRAN_Status_Badge

The LBSPR package contains functions to run the Length-Based Spawning Potential Ratio (LBSPR) method. The LBSPR package can be used in two ways: 1) simulating the expected length composition, growth curve, and SPR and yield curves using the LBSPR model and 2) fitting to empirical length data to provide an estimate of the spawning potential ratio (SPR).

The LBSPR method has been developed for data-limited fisheries, where few data are available other than a representative sample of the size structure of the vulnerable portion of the population (e.g., the catch) and an understanding of the life history of the species.

Installing

The LBSPR package can be installed from CRAN:

install.packages("LBSPR")

The development version of the package can be installed from GitHub using the devtools package:

# install.packages("devtools")
devtools::install_github("adrianhordyk/LBSPR")
