Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 12-15; Anal spines: 0; Anal soft rays: 15 - 22; Vertebrae: 39 - 41. Diagnosis: Body slender, depth about 20-25% of standard length; scutes strongly keeled, beginning just behind base of last pectoral fin ray, about 10-12 + 5-8; snout rather pointed; lower jaw slightly projecting, with small teeth; pre-maxillae with a single row of small teeth; maxilla slender, its blade a little more than 3 times longer than deep, upper edge a little ridged; second supra-maxilla slender, spatulate, with distinct anterior shaft; lower gillrakers 18-20 (Ref. 188, 47399). It resembles small Microthrissa congica, which has a much blunter snout and more anal finrays, 18-21 vs. 16-18 (Ref. 188).

A lacustrine species, but perhaps also in small streams or rivers feeding Lake Mweru (Ref. 188).

Estimates based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00933 (0.00449 - 0.01939), b=3.05 (2.88 - 3.22), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.1 ±0.3 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.).

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

Price category (Ref. 80766): Low.
