Category	Metric	Definition: relative abundance of … (percent)
Composition	Centr.TolTxPct	Centrarchid species (excludes tolerant species)
Composition	Percfm.TolPct	Perciformid individuals (excludes tolerant species)
Composition	SuckerCatPct	Catostomid and Ictalurid individuals
Habitat	LargeRiverPct	Individuals that predominately utilize large river habitats
Habitat	LargeRiverTxPct	Species that predominately utilize large river habitats
Habitat	MorFnotSH20.TolTxPct	Species that prefer moderate or fast current (excludes tolerant species)
Habitat	MorFnotSH20TxPct	Species that prefer moderate or fast current but not slow
Habitat	Wetland.TolTxPct	Species that utilize wetland habitats (excludes tolerant species)
Habitat	WetlandTxPct	Species that utilize wetland habitats
IBI^a	FIBI	Fish-based index of biotic integrity score computed for a given site
IBI^a	FIBI_BCG4	FIBI score normalized to the impairment threshold for the stream class of the site
Life history	LLvdPct	Long-lived individuals
Life history	MgrTxPct	Migratory species
Life history	SLvdTxPct	Short-lived species
Reproductive	CompLithPct	Complex lithophilic individuals
Reproductive	CompLithTxPct	Complex lithophilic species
Reproductive	MA.3TxPct	Species with a female mature age ≥ 3
Reproductive	NestNoLithTxPct	Non-lithophilic, nest-guarding species
Reproductive	PSpnTxPct	Prolific spawning species
Reproductive	SSpnTxPct	Serial spawning species
Tolerance	IntolerantTxPct	Intolerant species
Tolerance	SensitiveTxPct	Sensitive species
Trophic	DetPlnkTxPct	Detritivorous and planktivorous species
Trophic	GenFrimTxPct	Trophic generalist species

Trophic	SdetTxPct	Species where detritus constitutes at least 5 percent of their diet
Trophic	SWCGenTolTxPct	Tolerant species and generalist feeders that feed within the surface water column

^aIBI metric scores are computed using multiple metrics from other categories and are not defined by relative abundance
