C Appendix C: NuSEDS data dictionary crosswalk

This appendix documents how the updated guidance relates to NuSEDS fields and controlled vocabularies (see docs/context/Data_Dictionary_NuSEDS_EN.csv).

C.1 C.1 Enumeration method values (ENUMERATION_METHODS)

Table C.1: Suggested mapping from NuSEDS enumeration method values to the updated key method families (FS, V, A, S, T, R, P, M).

NuSEDS ENUMERATION_METHODS value	Suggested method family	Notes
Bank Walk	V
Based on Angling Catch	P	Catch-based index; treat as a CPUE-style index unless more detail is provided.
Biologist/Working Group	unknown	Not a method; treat as method-unknown unless a specific field/analysis method is documented elsewhere.
Boat	V
Broodstock Removal	FS
Dead Pitch	V	Carcass-based visual surveys; often paired with peak/cumulative dead estimation methods.
Electronic Counters	FS
Electroshocking	P
Enumeration by Hatchery	FS
Fence	FS
Fixed Wing Aircraft	A
Float	V
Helicopter	A
Hydroacoustic Station	S
Other	unknown	Treat as method-unknown unless a specific field/analysis method is documented elsewhere.
Peak Live and Dead Count	V	Value is analysis-like; prefer capturing peak/cumulative variants under ESTIMATE_METHOD.
Redd Counts	R
Snorkel	V
Spot Checks	V
Stream Walk	V
Strip Counts	V
Tag Recovery	M
Trap	T	If trap is non-spanning or efficiency-corrected, use T; fully constraining traps may behave more like fixed-site counting.
Walk	V

C.2 C.2 Estimate method values (ESTIMATE_METHOD)

Table C.2: Suggested interpretation of NuSEDS estimate method values under the updated guidance. Where ‘depends’ appears, additional method metadata are required to apply the key cleanly.

NuSEDS ESTIMATE_METHOD value	Guidance interpretation	Suggested method family	Notes
Cumulative CPUE	CPUE index	P
Fixed Site Census	Enumeration device/mode (often stored as estimate method)	FS
Cumulative New	NA	NA
Peak Live + Dead	Visual-series estimation (AUC/peak variants and expansions)	V
Area Under the Curve	Visual-series estimation (AUC/peak variants and expansions)	V
Mark & Recapture: Jolly-Seber	Mark-recapture estimation	M
Addition/Subtraction	Math/expansion operations (depends on base method)	depends
Multiplication/Division	Math/expansion operations (depends on base method)	depends
Mark & Recapture: Petersen	Mark-recapture estimation	M
Redd Count	Redd-based estimation (often requires spawners-per-redd conversion)	R
Peak Live + Cumulative Dead	Visual-series estimation (AUC/peak variants and expansions)	V
Lake Expansion	Math/expansion operations (depends on base method)	depends
Insufficient Information	Method unknown/administrative label	unknown
Peak Live * Expansion	Visual-series estimation (AUC/peak variants and expansions)	V
Unknown Estimate Method	Method unknown/administrative label	unknown
Not Applicable	Method unknown/administrative label	unknown
Expert Opinion	Method unknown/administrative label	unknown
Mark & Recapture: Bayesian	Mark-recapture estimation	M
Other Estimate Method	Method unknown/administrative label	unknown
Sonar-DIDSON	Hydroacoustic modelling pipeline	S
Calibrated Time Series	Calibrated time series (requires calibration source + diagnostics)	depends	For interpretability, record calibration source years, diagnostics, and revision history.
Resistivity Counter	Enumeration device/mode (often stored as estimate method)	FS	Enumerated as a device/mode; ensure bypass/coverage/QA metadata are captured to support Type 1/2 eligibility.
Sonar-ARIS	Hydroacoustic modelling pipeline	S
Mark & Recapture: Open Model	Mark-recapture estimation	M
Combined Methods	Combined-method workflow (requires explicit component listing)	depends	Decompose into components (e.g., sonar + visual apportionment; fence + visual during breach) and apply conservative classification.
Video Counter	Enumeration device/mode (often stored as estimate method)	FS	Enumerated as a device/mode; ensure QA review rate and uptime/coverage metadata are captured.
(Peak Live+Cum Dead)*Expansion	Visual-series estimation (AUC/peak variants and expansions)	V
