Teleostei (teleosts) > Siluriformes (Catfishes) > Claroteidae (Claroteid catfishes)
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).
Eponymy: These species are named after both Lake Turkana, Kenya, and the Turkana people, who are the predominant tribe in that area. (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal 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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00456 - 0.02402), b=2.98 (2.80 - 3.16), 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. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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