Estimates based on models

Preferred temperature (Ref. 115969): 7.5 - 14.8, mean 11.3 (based on 125 cells).

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

Bayesian length-weight: a=0.00457 (0.00219 - 0.00954), b=3.13 (2.93 - 3.33), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.1 se; based on diet studies.

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

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

Price category (Ref. 80766): Low.
