Etymology: Sauvagella: Because of Sauvage, 1860-1880 and 1875-1891; ichtyologist that studied the Ogowe; author of "Histoire naturelle des poissons de Madagascar"; madagascariensis: Named for the island to which it is endemic, Madagascar (Ref. 33664).

Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais (total) : 13 - 17; Espinhos anais: 0; Raios anais : 17 - 19; Vértebras: 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).

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

Índice de diversidade filogenética (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).

Nível Trófico (Ref. 69278): 3.1 ±0.3 se; based on size and trophs of closest relatives

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
