Estimates based on models

Preferred temperature (Ref. 123201): 25.1 - 29.2, mean 27.3 °C (based on 528 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5664 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00363 (0.00147 - 0.00899), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.6 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec is assumed to be <10).

Fishing Vulnerability (Ref. 59153): High vulnerability (65 of 100).

Paragaleus longicaudatus (Bessednov, 1966)
