Estimates based on models

Preferred temperature (Ref. 123201): 11.1 - 22.7, mean 17.9 °C (based on 65 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00442 - 0.02595), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.3 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (43 of 100).
