A suite of model-based management procedures (MPs) included in the package. Additional MPs, with specific model configurations (e.g., stock-recruit function or fixing certain parameters) or alternative ramped harvest control rules can be created with make_MP and the available Assess and HCR objects with constant TAC between assessment years.

Arguments

x

A position in the Data object.

Numeric, the number of stochastic replicates for the management advice.

diagnostic

Character string describing the assessment diagnostic to save, see make_MP.

Value

An object of class Rec which contains the management recommendation.

Functions

  • SCA_MSY: A statistical catch-at-age model with a TAC recommendation based on fishing at FMSY, and default arguments for configuring SCA.

  • SCA_75MSY: An SCA with a TAC recommendation based on fishing at 75% of FMSY.

  • SCA_4010: An SCA with a 40-10 control rule.

  • DDSS_MSY: A state-space delay difference model with a TAC recommendation based on fishing at FMSY, and default arguments for configuring DD_SS.

  • DDSS_75MSY: A state-space delay difference model with a TAC recommendation based on fishing at 75% of FMSY.

  • DDSS_4010: A state-space delay difference model with a 40-10 control rule.

  • SP_MSY: A surplus production model with a TAC recommendation based on fishing at FMSY, and default arguments for configuring SP.

  • SP_75MSY: A surplus production model with a TAC recommendation based on fishing at 75% of FMSY.

  • SP_4010: A surplus production model with a 40-10 control rule.

  • SSS_MSY: Simple stock synthesis (terminal depletion fixed to 0.4 in SSS) with a TAC recommendation based on fishing at FMSY.

  • SSS_75MSY: Simple stock synthesis (terminal depletion fixed to 0.4) with with a TAC recommendation based on fishing at 75% FMSY.
