Etymology: Engraulicypris: Greek, eggraulis, -eos = anchovy + Greek, kypris = the name of Aphrodite, proceeding from Kypris, (Cyprus), Greek, kyprinos = carp (Ref. 45335); gariepinus: The species name gariepinus refers to the Gariep, a San name for the Orange River that means 'great water' (Ref. 116496).

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 9 - 10; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 17 - 19; позвонки: 36 - 38. Diagnosis: Caudal fin membrane clear to pale orange towards midline; anal fin extending over three quarters of length of caudal peduncle; caudal peduncle short; operculum entirely, not partially, shiny; body midline silver, not black; iris dark to light grey, not white; head with tubercles along lower jaw and lower head in breeding males; snout rounded, with dense dark spotting on tip; pelvic fin melanophores absent (Ref. 116496).
This shoaling fish favours open, shallow water, normally occurring in slack pools and particularly below riffles; populations found in the lower Orange and Fish Rivers are limited by the Augrabies and Fish River Falls; they are restricted to turbid waters, which provide protection from visual predators (Ref. 116496). They are thought to feed mainly on small autochthonous invertebrates, e.g. planktonic crustaceans or insects, and are caught in large numbers where they occur (Ref. 116496).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.

Trophic level (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
