In Blue-Matter/MSEtool: Management Strategy Evaluation Toolkit

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()
)

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.

Value

A nested list by fleet with updated population dynamics
