Management-procedure components

Management-Procedure Components

This page summarizes the structure described in SCW17/Paper-03. In jmMSE, a management procedure normally has three parts:

flowchart TD
  D["Observed annual data"] --> E["Calculate a stock or index indicator"]
  E --> S["Indicator used by the rule"]
  S --> H["Harvest control rule: hcr"]
  H --> R["Catch recommendation"]
  R --> I["Apply catch limits and allocation rules"]
  I --> A["Implemented catch by fishery or stock"]

Part	Fisheries meaning	Function names used in the code
Indicator calculation (`est`)	Converts observations or assessment results into the indicator used by the rule.	`perfect.sa`, `shortcut.sa`, `cpue.ind`, `cpuescore.ind`, `meta.est`, `spict.sa`
Harvest control rule (`hcr`)	Converts the indicator into a catch or fishing-effort recommendation.	`fixedC.hcr`, `hockeystick.hcr`, `buffer.hcr`, `bufferdelta.hcr`, `meta.hcr`
Catch limits and allocation (`isys`)	Applies annual limits or allocates the recommendation among fisheries or stocks.	`split.is`, `bank_borrow.is`

Family	Typical estimator	Typical HCR	Role at SCW17
Fixed catch reference	Perfect information	Fixed catch	Diagnostic baseline
Shortcut assessment	Depletion estimate	Hockeystick or buffer	Assessment-based comparison
Empirical index	CPUE/index aggregate	Buffer or hockeystick	Main CMP development family
SPiCT assessment	SPiCT biomass/status	Buffer	Model-based candidate
Multi-index/meta	Multiple index scores	Meta-HCR	Exploratory candidate
Banking/borrowing	Existing estimator/HCR	Existing HCR plus modified `isys`	Implementation sensitivity

This is a list of approaches that were considered, not a decision about which procedure should be selected. A complete CMP definition must state the exact calculation methods, parameter values, input data, and catch-allocation rules.
