Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 17 - 19; Raggi dorsali molli (totale) : 8 - 9; Spine anali: 3; Raggi anali molli: 7 - 8. Diagnosis: Absence of a dark submarginal band in the dorsal fin distinguishes Petrotilapia flaviventris from males of P. microgalana, P. genalutea, P. nigra, P. chrysos, P. mumboensis, and P. pyroscelos, which have such a band (Ref. 87181). Adult males of P. flaviventris are yellow on ventral and mid flank with scales outlined in blue; the dorsal one-third is blue to gray with yellow and orange highlights; cheeks and throat are yellow to orange; males of P. tridentiger are light blue with dark blue bars; while those of P. xanthos are yellow; adult male, and female, P. palingnathos have distinctly retrognathous jaws and can thus be distinguished from those of P. flaviventris (Ref. 87181). Females of P. flaviventris are yellow brown with interrupted black horizontal stripes and with a background colouration fading to dark brown dorsally, which distinguishes them from those of P. tridentiger, which are brown, and from P. chrysos and P. microgalana, which are golden yellow; females of P. flaviventris are further distinguished from those of P. xanthos, which are light brown (Ref. 87181).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [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).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

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