Ictaluridae (North American freshwater catfishes)
Etymology: Noturus: Greek, noton = back + Greek, oura = tail; refred to the position of the tail over the back (Ref. 45335); stigmosus: stigmosus meaning marked or branded, referring to the two light spots typically present just anterior to the dorsal spine (Ref. 10294).
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; demersal. Temperate; 43°N - 36°N
North America: Lake Erie and Ohio River basins from western Pennsylvania, southern Michigan and eastern Kentucky to Ohio River in western Kentucky, USA; tributaries of Mississippi River in western Tennessee and northern Mississippi, USA.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00250 - 0.01326), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.58 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
