Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 0; Anale stekels: 0. Scutes apparent along belly. Upper jaw with distinct median notch. Pectoral fin tip short of pelvic fin base by width of 3 to 7 scales; pelvic fin with oblique and almost straight hind margin. Pre-dorsal scales modified; scales on back and above base of anal fin not markedly smaller than rest. A black spot behind gill opening, but none along flank.

Forms schools (Ref. 188). The morphological characteristics observed and the composition of the trophic spectrum indicate that this species is a filter-feeder, consuming mainly phytoplankton (Ref. 34154).

Estimates based on models

Preferred temperature (Ref. 115969): 12.6 - 22.8, mean 16.8 (based on 104 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00794 (0.00471 - 0.01341), b=3.06 (2.92 - 3.20), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 2.8 ±0.31 se; based on food items.

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Assuming tm=1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (24 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (79 of 100).
