SPRFMO Jack Mackerel Candidate Management Procedures
This site distinguishes test candidates, shortlisted candidates, and adopted management procedures. Inclusion in the registry does not imply endorsement or adoption.
Purpose
This site describes the candidate management procedures (CMPs) being evaluated for South Pacific jack mackerel. It draws mainly on the current jmMSE analysis and brings together:
- the focal HS-20 (MP43) and PR-20 (MP44) candidate definitions;
- the earlier HS+20 (MP29) and PR+20 (MP32) specifications retained as sensitivity cases, plus four other annual-limit comparison cases;
- the full management strategy evaluation (MSE) process;
- results from tuning, trade-off, and robustness comparisons; and
- instructions for applying a selected procedure when new annual data become available.
SCW17 Papers 03, 04, 08, and 09 provide historical context and documentation structure, but they do not define the current candidate registry.
The MSE calculations remain in SPRFMO/jmMSE. This site records what each CMP is, why it remains under consideration, how it would be applied, and which analysis supports it.
Start here
- CMP registry: focal, sensitivity, and comparison cases with stable legacy identifiers and current HS/PR labels.
- MP43 and MP44: focal-case controls, rules, and current analytical results.
- MP29 and MP32: the earlier +20 sensitivity specifications and annual calculation details; the registry and SC14 report give the focal MP43/MP44 controls.
- Annual application: steps from receiving new data to producing advice.
- Slick explorer: compare the eight SC14 MSE cases interactively.
- How the MSE work fits together: where CMPs fit within the assessment and simulation system.
- Background and results: current
jmMSEresults with SCW17 development context. - Sources and record of changes: sources, review status, and a record of changes.
- Checks of agreement among the SC14 files: named release, run list, file list, and automatic numerical comparisons.
Governing principle
The approved CMP specification is separate from background explanations and MSE results. New scientific results may change whether a candidate is retained, but they do not automatically change its data inputs, harvest control rule, parameter values, catch-allocation method, or exceptional-circumstances rules.
Terms used on this site
| Term | Meaning |
|---|---|
| CMP | Candidate management procedure: the complete rule for turning agreed data into management advice. |
| HCR | Harvest control rule: the part of a CMP that converts a stock or index indicator into a catch or fishing-effort recommendation. |
| Operating model (OM) | A simulated description of the stock and fishery used to test a CMP. Alternative OMs represent different plausible assumptions. |
| Performance measure | A quantity used to compare CMPs, such as catch, spawning biomass, biological risk, or year-to-year catch variation. |
| IACC | Interannual catch change: a measure of how much catch changes from one year to the next. |
