Etymology: Tilapia: Bechuana, African native thiape = fish (Ref. 45335);  pra: The species name pra refers both to the Akan word 'pra' (river) of the Kwa language family spoken in Ghana and to the River Pra, from which drainage the holotype was collected; it refers to the riverine distribution as compared to the lacustrine distribution of its apparent sister taxon Tilapia busumana; a noun in apposition (Ref. 84667).

Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 14 - 16; Rayons mous dorsaux (Total): 11-12; Épines anales 3; Rayons mous anaux: 8 - 10. Diagnosis: Tilapia pra is distinguished from all other Tilapia sensu lato except T. sparrmanii, T. ruweti, T. guinasana, T. baloni, T. brevimanus, T. busumana, Pelmatolapia mariae and Pelmatolapia cabrae, in having bicuspid pharyngeal teeth in the posterior two rows of lower pharyngeal jaw (Ref. 84667). It differs from T. baloni and T. ruweti in having more gill rakers on first ceratobranchial, lower, gill-arch, 10-12 vs. 6-9; from T. guinasana in having a higher number of upper lateral line scales, 18-22 vs. 14-17; and from T. sparrmanii in a combination of a higher number of upper lateral line scales, 18-22 vs. 14-19, a shorter anal fin base, 15.0-18.6% of standard length vs. 18.0-23.8%, and a lower number of vertical stripes, 6-7 vs. 8-9 (Ref. 84667). It further differs from Pelmatolapia mariae and P. cabrae in having fewer scales on the lower lateral line, 8-11 vs. 10-14, and not having spatulate shaped teeth in the outer row of both jaws; from T. brevimanus in having fewer gill rakers on the ceratobranchial gill-arch, 10-12 vs. 12-16, and not having spatulate shaped teeth in the outer row of both jaws; from T. busumana in possessing a longer last dorsal-spine, 16.2-21.3% of standard length vs. 11.6-14.9%, a shorter lower lip length, 8.0-10.7% of standard length vs. 9.6-13.9%, and a shorter lower jaw length, 9.9-13.6% of standard length vs. 10.5-15.2%; in addition, it differs from T. busumana in ground colouration: Tilapia pra possesses a light brown to greyish dorsum and a beige to yellow ventral area vs. a bluish-purple to blackish dorsum and darker on underside of head and body of T. busumana (Ref. 84667).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [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. 93245).
Niveau trophique (Ref. 69278):  2.3   ±0.2 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
