Dorsale stekels (totaal) : 14 - 17; Dorsale zachte stralen (totaal) : 9 - 12; Anale stekels: 3; Anale zachte stralen: 8 - 9. Diagnosis: 12-17 rakers on lower limb of first arch; 27-30 scales in lateral line; generally with black spots and blotches on head and body (Ref. 81260).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Estuarine species, preferring brackish water but found in freshwater during low tide (Ref. 68431). Male mouthbrooder (Ref. 41581). No marked sexual dichromatism when sexually active; forms temporary pair-bonds during reproduction (Ref. 81260).

Levenscyclus en paargedrag Maturities | Voortplanting | Spawnings | Egg(s) | Fecundities | Larven

Males carry eggs (Ref. 41581). Males of Sarotherodon nigripinnis dolloi construct nest and incubate eggs (Ref. 55074). Incubatory period lasts about 14 days; female retrieves newly released young in mouth (Ref. 72506). Juveniles become independant after about 4 weeks (Ref. 55074).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00827 - 0.04391), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  2.3   ±0.2 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (12 of 100).
