Etymology: Stemonosudis: Greek, stemon, -onos = warp, weft + Latin, sudis = esox, fish of the Rhine, cited by Plinius 9.15; it also means "stake" (Ref. 45335); fumea: Name 'fumea' from the Latin word meaning 'smoky', in reference to the grayish coloration of large adults of the new species.

Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00186 (0.00077 - 0.00449), b=3.13 (2.92 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.8 ±0.6 se; based on size and trophs of closest relatives |
|
Resilience (Ref. 120179) |
High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.). |
|
Fishing Vulnerability (Ref. 59153) |
Low to moderate vulnerability (28 of 100). 🛈 |
