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 its type locality, Madagascar.
Environment / Climate / Range
Freshwater; brackish; pelagic. Tropical, preferred ?; 11°S - 26°S, 42°E - 50°E (Ref. 188)
Africa: endemic to Madagascar.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 49.7 cm SL (female)
soft rays: 17 - 19;
Vertebrae: 41 - 43. Body a little compressed, belly rounded, without pre-pelvic scutes, but a pelvic scute present with slender vertical arms. Gill rakers probably few. Last two anal fin rays not separate from others (cf. Spratellomorpha bianalis). Distinguished from other non-scuted clupeids in area (Spratelloides, Dussumieria, Etrumeus) by presence of normal pelvic scute (cf. W-shaped) (Ref. 188). Body depth 15.8-21.1% SL. Snout 26.2-33.7% HL (Ref. 33664). Scales are cycloid and easily shed (Ref. 56161). Two color forms, yellow and red or orange, have been noted in Sauvagella madagascariensis (Ref. 56161).
Occurs in fresh and brackish water habitats in mid and lower reaches of eastern coastal rivers and Pangalanes Canal network (Ref. 33664).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00409 - 0.02131), b=3.07 (2.87 - 3.27), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (45 of 100) .
