Etymology: Bathyraja: Greek, bathys = deep + Latin, raja, -ae = a ray (Raja sp) (Ref. 45335); andriashevi: Named in honor of the Soviet ichthyologist, Anatoly Petrovich Andriashev (Ref. 31387).
Eponymy: Professor Dr Anatoly Petrovich Andriyashev (1910–2009) was a Russian marine biologist. [...] (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 2.5 - 3.8, mean 3 °C (based on 58 cells).

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

Bayesian length-weight: a=0.00550 (0.00291 - 0.01038), b=3.13 (2.97 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.7 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): High vulnerability (63 of 100).
