Estimates based on models

Preferred temperature (Ref. 115969): 3.5 - 5.4, mean 4.7 (based on 22 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00550 (0.00273 - 0.01106), b=3.10 (2.93 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.5 ±0.37 se; based on food items.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).

Insentiraja subtilispinosa (Stehmann, 1989)
