ML2D: 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

A table of nsim rows and 2 columns (depletion, fishing mortality rate)
