Estimates based on models

Preferred temperature (Ref. 123201): 23.1 - 28.1, mean 27.3 °C (based on 111 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00458 - 0.01258), b=3.09 (2.94 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 4.0 ±0.61 se; based on food items.

Generation time: 3.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (K=0.36; tm=2; tmax=6).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).
