YPR_CC: Yield Per Recruit analysis to get FMSY proxy F01 paired to a naive catch curve estimate of recent Z

Description

A simple yield per recruit approximation to FMSY (F01) which is the position of the ascending YPR curve for which dYPR/dF = 0.1(dYPR/d0) A naive catch-curve analysis is used to determine recent Z which given M (Mort) gives F and thus abundance = Ct/(1-exp(-F))

Usage

YPR_CC(x, Data, reps = 100, Fmin=0.005)

Arguments

x

A position in a data-limited methods data object

Data

A data-limited methods data object (class DLM)

reps

The number of samples of the TAC

Fmin

The minimum fishing mortality rate inferred from the catch-curve analysis
