find_spat_f: find spatial Fs (fishing mortality rates)

In pdolder/MixFishSim: Mixed Fishery fleet dynamics simulation tool

find spatial Fs (fishing mortality rates)

Description

find_spat_f uses uniroot to find the fishing mortality rate for a population given the catch, biomass and natural mortality using the baranov_f objective function.

Usage

find_spat_f(sim_init = NULL, C = C, B = B, M = M, FUN = baranov_f)

Arguments

sim_init	is the parameterised sim settings, made by init_sim
C	is a Numeric vector detailing the catch at wk_{t}
B	is a Numeric vector of the biomass at wk_{t}
M	is a Numeic vector of the natural mortality rate at wk_{t}
FUN	is the objective function, here the Baranov equation baranov_f

Value

Gives a matrix the spatial fishing mortality estimate F

Examples

find_spat_f(sim_init = sim, C = matrix(1000,3000, nc =2), B =
matrix(12000,10000, ncol = 2), M = 0.2, FUN = baranov_f)
