ML2D {MSEtool}

Depletion and F estimation from mean length of catches

Description

A highly dubious means of getting very uncertain estimates of current stock biomass and (equilibrium) fishing mortality rate from growth, natural mortality rate, recruitment and fishing selectivity.

Usage

ML2D(OM, ML, nsim = 100, ploty = T, Dlim = c(0.05, 0.6))

Arguments

OM

An object of class 'OM'

ML

A estimate of current mean length of catches

nsim

Number of simulations

ploty

Produce a plot of depletion and F

Dlim

Limits on the depletion that is returned as a fraction of unfished biomass.

Value

An object of class 'OM' with 'D' slot populated
