Korte beschrijving Morfologie | Morfometrie

Dorsale zachte stralen (totaal): 11; Anale zachte stralen: 29 - 31; Wervels: 39 - 41. Can be distinguished by having dark blotch at the humeral region, a character shared only with Acestrocephalus boehlkei and Acestrocephalus stigmatus. Differs from Acestrocephalus stigmatus by having 25-27 anal-fin rays (vs. 29-31), and 7-8 gill-rakers (vs. 5-6). This species has a quite peculiar general structure of the pseudotympanum which differs from that of Acestrocephalus stigmatus and all the other species of Acestrocephalus examined. Acestrocephalus maculosus has very reduced muscular hiatus as a result of the great development of the obliquus superioris muscle covering the anterior portion of the swim bladder. This makes the opening anterior to first pleural rib, this and the second pleural rib as well as the obliquus inferioris muscle not visible (Ref. 75890).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00415 - 0.02411), b=3.08 (2.87 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.6   ±0.5 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 (10 of 100).
