Estimates based on models

Preferred temperature (Ref. 123201): 7.7 - 21.8, mean 17.9 °C (based on 89 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00575 (0.00362 - 0.00916), b=3.03 (2.90 - 3.16), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.50 se; based on food items.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).

Price category (Ref. 80766): Medium.
