Etymology: Chrysichthys: Greek, chrysos = golden + Greek, ichthys = fish (Ref. 45335); turkana: The species name is alluding to the type locality and predominant tribe in northwestern Kenya (Ref. 78586).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
Africa: restricted to Lake Turkana, Kenya (Ref. 78586).

Morphology | Morphometrics
soft rays: 10 - 11. Tooth bands of the premaxillae forming a broad arc of uniform width with squared ends and a shallow notch anteromedially (Ref. 78586). Prevomerine tooth patches separated at the midline and accessory tooth plates narrowing posteriorly to a sharp point along a smooth curve (Ref. 78586). Postcleithral process well developed and projecting sharply posteriad (Ref. 78586). Horizontal eye diameter contained 2.7-3.1 times in head length and interorbital width contained 3.8-7.7 times in head length (Ref. 78586).
Demersal during the day; locally abundant between 10 and 25 m depth zones; migrates closer to shore at dusk to feed on chironomid larvae and ostracods; onset of maturity at rather small size (60-70 mm) and extended reproductive period (Ref. 78586).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00368 - 0.01970), b=3.02 (2.84 - 3.20), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
