catchMSYModel: Age-structured Catch-MSY model

In smartell/CatchMSY: Catch-MSY method for estimating MSY-based reference points

Description

An age-structured assessment model paramterized using MSY and FMSY as the leading parameters, and the instantaneous natural mortality rate. This function generates biomass estimates, estimates of fishing mortality rates, and stock depletion. It also returns statistical criterion depending on the available data, and non-statistical criterion based on satisfying user specified constraints.

Usage

catchMSYModel(sID, nlSearch = FALSE, selex = FALSE)

Arguments

sID	Stock ID object Set to TRUE when including the prior on sel1 (sel50)
nlSearch	Boolean flag to turn off non-statistical criterion for non-linear search. Set to TRUE when using non-linear search routines.
selex	Boolean flag to turn off search across sel1 (sel50) parameter.

Details

The age-structured model is conditioned on the historical catch data (in weight). The catch equation assumes that both fishing mortality and natural mortality are occuring simultaneously, and the instantaneous fishing mortality rate is found by solving the Baranov catch equation C = F/Z*(1-exp(-Z))*B, for F.
