Reference points

Calculate MSY and Sgen reference points for the operating model. Uses the biological parameters (maturity, natural mortality) in the last year of the projection.

Usage

calc_ref(SOM, rel_F, check = TRUE)

Arguments

SOM

An object of class SOM

rel_F

Numeric length 2, indicates the relative effort in the preterminal and terminal fisheries, with a maximum value of 1. For example, c(1, 0) indicates a yield calculation for only the preterminal fishery. By default, uses the ratio of the harvest rates in the operating model.

check

Logical, whether to check the SOM object using check_SOM()

Value

Matrix of various state variables (catch, exploitation rate, egg production, spawners) at MSY and Sgen by simulation
