Etymology: Microthrissa: Grek, mikros = small + Greek, thrissa, -es = shad (Ref. 45335).
Environment / Climate / Range
Freshwater; pelagic. Tropical; 10°N - 10°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.0 cm SL male/unsexed; (Ref. 188)
soft rays: 16 - 27. Body slender; scutes strongly keeled, beginning under pectoral fin base, 20 to 22 total; snout blunt or acute; lower jaw not or slightly projecting, included in upper when mouth closed, with small teeth; pre-maxillae with a single row of small teeth; maxilla blade more than 3 times as long as deep, upper edge quite strongly ridged; second supra-maxilla slender, spatulate, with distinct anterior shaft (Ref. 188).
Africa: widely distributed in the Congo River basin, from the lower Congo near its estuary up to the upper Lualaba, but excluding the Luapula-Moero (Ref. 47399).
Occurs in rivers and lakes, apparently in both still and running water; seems to occur in rather acid waters.

Phylogenetic diversity index (Ref. 82805
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00456 - 0.02002), b=3.05 (2.88 - 3.22), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.1 ±0.41 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
