CalcMPDynamics_MF: Calculate population dynamics from MP recommendation for multi-fleet operating models

Description

An internal function to calculate the population dynamics for the next time step based on the recent MP recommendation. First uses .CalcMPDynamics_SelRetDisc to update selectivity, retention, and discarding parameters for individual fleets, then calculates F from effort or catch recommendations simultaneously across all fleets.

Usage

CalcMPDynamics_MF(
  MPRecs_f,
  y,
  nyears,
  proyears,
  nsim,
  LastTAE,
  histTAE,
  LastSpatial,
  LastAllocat,
  LastTAC,
  TACused,
  maxF,
  Effort_pot,
  StockPars,
  FleetPars_f,
  ImpPars_f,
  checks = FALSE,
  control = list()
)

Value

A nested list by fleet with updated population dynamics

Arguments

MPRecs_f

A nested list first by fleet (length nf), then the various MP recommendations (MPRecs, see CalcMPDynamics()).

y

The projection year

nyears

The number of historical years

proyears

The number of projection years

nsim

The number of simulations

LastTAE

A matrix [nsim, nf] with the most recent TAE

LastSpatial

An array [nareas, nsim, nf] with the most recent spatial management arrangements

LastAllocat

A matrix [nsim, nf] with the most recent allocation

LastTAC

A matrix [nsim, nf] with the most recent TAC

TACused

A matrix [nsim, nf] with the most recent TAC

maxF

A numeric value with maximum allowed F. From OM@maxF

Effort_pot

A matrix [nsim, nf] of potential effort

StockPars

A list of stock parameters

FleetPars_f

A nested list first by fleet, then each containing the respective fleet parameters

ImpPars_f

A nested list first by fleet, then each containing the respective implementation error parameters

checks

Logical. Run internal checks? Currently not used.

control

List of control parameters used internally.
