Estimates based on models

Preferred temperature (Ref. 123201): 2.3 - 13, mean 9.9 °C (based on 221 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00138 (0.00083 - 0.00229), b=3.22 (3.07 - 3.37), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.30 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).

Hymenogadus gracilis (Gilbert & Hubbs, 1920)
