Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 13-17; Épines anales 0; Rayons mous anaux: 17 - 19; Vertèbres: 41 - 43. Diagnosis: Body elongate, a little compressed; belly rounded, without pre-pelvic scutes, but a pelvic scute present with slender lateral arms; gillrakers few, 17-20 gillrakers on lower limb of first arch; pelvic fin with 1 unbranched and 7 branched finrays, a little anterior to dorsal fin origin; last two anal finrays not separate from others (Ref. 188, 33664). It is distinguished from other non-scuted clupeids of Spratelloides, Dussumieria and Etrumeus by presence of a normal pelvic scute vs. W-shaped (Ref. 188). It is distinguished from Sauvagella robusta by a higher vertebral number, 41-43 vs. 38-40; a shallower body, 15.8-21.1% of standard length vs. 20.8-27.4%; a longer snout, 26.2-33.7% of head length vs. 18.5-26.6%; and a higher anal fin ray count, 17-19 vs. 13-17 (Ref. 33664).

Biologie     Glossaire (ex. epibenthic)

Found in freshwaters, possibly tolerating brackish water (Ref. 188); from sea level to about 450m, mostly in smaller rivers and streams and usually in forested areas (Ref. 56161). Probably planktivorous (Ref. 56161).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00365 - 0.02081), b=3.02 (2.81 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.1   ±0.3 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
