Estimates based on models

Preferred temperature (Ref. 123201): 8.4 - 10.6, mean 9.5 °C (based on 8 cells).

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

Bayesian length-weight: a=0.01000 (0.00495 - 0.02022), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.5 se; Based on size and trophs of closest relatives.

Resilience (Ref. 120179): Very low, minimum population doubling time more than 14 years (tm=15; tmax=85).

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

Price category (Ref. 80766): Medium; Questionable: based on ex-vessel price for species in this genus.
